Answer:
25 chapter books
Step-by-step explanation:
117 - (23×4)
[23×4=92]
.°. 117 - 92 = 25
Step-by-step explanation:
Total Shelf Capacity = Capacity per shelf x Number of Shelves

Find the volume of the given solid. Bounded by the coordinate planes and the plane 9x + 5y + z = 45.
The volume of the given solid that is bounded by the coordinate planes and the plane 9x + 5y + z = 45 is 45 units³.
What is volume?Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected.For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.So, we have: 9x + 5y + z = 45
Let us consider z = 0.
Then we have:
9x + 5y = 45
Now, we obtain:
x = 45/9 - y
OR
y = 45/5 - x
Hence,
45/9 × 45/5
2,025/45
45 units³
Therefore, the volume of the given solid that is bounded by the coordinate planes and the plane 9x + 5y + z = 45 is 45 units³.

B)What weight would represent the 25th percentile?
C)What weight would represent the 75th percentile?
D) What is the interquartile range of male Labrador weights?
E)What proportion of male adult Labrador retrievers weigh above 85 pounds?
F) What proportion of male adult Labrador retrievers weigh between 60 and 80 pounds?
G) What proportion of male adult Labrador retrievers weigh less than 65 pounds?
Answer:the photo is for part A.
B) the weight would be Invnorm(.25,77,6)=72.95
C)the weight would be 81.04 but this is the work invnorm(.75,77,6)=81.04
D)IQR=Q3-Q1

E)9.12 is the answer the work normalcdf(85,1000,77,6)=.0912
F).6892 or 68.92% are the answers the work normalcdf(60,80,77,6)=.6892
G).0227 or 2.27% is the answer and the work normalcdf(0,65,77,6)=.0227
Step-by-step explanation:
Using the normal distribution, we have that:
a) The sketch is given at the end.b) A weight of 72.95 pounds would represent the 25th percentile.c) A weight of 81.05 pounds would represent the 75th percentile.d) The interquartile range is of 8.1 pounds.e) 0.0918 = 9.18% of male adult Labrador retrievers weigh above 85 pounds.f) 0.6892 = 68.92% of male adult Labrador retrievers weigh between 60 and 80 pounds.g) 0.0228 = 2.28% of male adult Labrador retrievers weigh less than 65 pounds.----------------------
Problems of normal distribution can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
----------------------
Mean of 77 means that \(\mu = 77\)Standard deviation of 6 means that \(\sigma = 6\)As for item a, the sketch is given at the end of the question.----------------------
Item b:
The weight is X when Z has a p-value of 0.25, so X when Z = -0.675.\(Z = \frac{X - \mu}{\sigma}\)
\(-0.675 = \frac{X - 77}{6}\)
\(X - 77 = -0.675(6)\)
\(X = 72.95\)
A weight of 72.95 pounds would represent the 25th percentile.
----------------------
Item c:
The weight is X when Z has a p-value of 0.75, so X when Z = 0.675.\(Z = \frac{X - \mu}{\sigma}\)
\(0.675 = \frac{X - 77}{6}\)
\(X - 77 = 0.675(6)\)
\(X = 81.05\)
A weight of 81.05 pounds would represent the 75th percentile.
----------------------
Item d:
The interquartile range is the difference between the 75th and the 25 percentile, thus:
\(81.05 - 72.95 = 8.1\)
The interquartile range is of 8.1 pounds.
----------------------
Item e:
The proportion is 1 subtracted by the p-value of Z when X = 85, thus:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{85 - 77}{6}\)
\(Z = 1.33\)
\(Z = 1.33\) has a p-value of 0.9082.
1 - 0.9082 = 0.0918.
0.0918 = 9.18% of male adult Labrador retrievers weigh above 85 pounds.
----------------------
Item f:
The proportion is the p-value of Z when X = 80 subtracted by the p-value of Z when X = 60, thus:
X = 80:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{80 - 77}{6}\)
\(Z = 0.5\)
\(Z = 0.5\) has a p-value of 0.6915.
X = 60:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{60 - 77}{6}\)
\(Z = -2.83\)
\(Z = -2.83\) has a p-value of 0.0023.
0.6915 - 0.0023 = 0.6892.
0.6892 = 68.92% of male adult Labrador retrievers weigh between 60 and 80 pounds.
----------------------
Item g:
This proportion is the p-value of Z when X = 65, thus:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{65 - 77}{6}\)
\(Z = -2\)
\(Z = -2\) has a p-value of 0.0228.
0.0228 = 2.28% of male adult Labrador retrievers weigh less than 65 pounds.

What are the limitations of using the Fundamental Counting Principle when determining the probability of an outcome??
The limitations of using the Fundamental Counting Principle when determining the probability of an outcome is that it is not simple and it does not apply to non-uniform probability distribution
What is probability?Probability is the likelihood or chance of an event happening or not.
Probability values helps in decision-making in day-to-day activities.
The Fundamental Counting Principle in probability is a way to determine the number of outcomes in a probability problem. It states that if there are p ways to do one thing and q ways to do another, the number of way to do both things is p × q.
However, this principle is limited for non-uniform probability distribution and for larger samples space.
Therefore, the limitations of using the Fundamental Counting Principle when determining the probability of an outcome is that it is not simple and it does not apply to non-uniform probability distribution.

5. A particle P travels in a straight line through a fixed point 0. Its distance s metres,
from O is given by s = t - 98 + 15t + 40, where t is the time in seconds after
motion has begun. Calculate
(a) the distances of P from 0 when its velocity is instantaneously zero,
(b) the values of t when the acceleration has a magnitude of 9 ms ?,
(c) the average speed of P during the first two seconds,
(d) the total distance travelled in the first six seconds.
guys! help me with part (d) please!
answers for part (a), (b) and (c) are: 15 and 47, 4.5, 26 respectively.
(a) The distance of P from O when it is instantaneously at rest is 40 metres. (b) The values of t are 5 and 1 second. (c) The average velocity = 2/2 = 1 m/s. (d) The total distance travelled in the first 6 seconds is -234 meters.
What is the velocity?Velocity is defined as the displacement of the object in a given amount of time and is referred to as velocity.
a) To find the distance of P from O when it is instantaneously at rest, we need to find the value of s when t = 0.
s = t³ - 9t² + 15t + 40
s = 0 - 9(0)² + 15(0) + 40
s = 40
So the distance of P from O when it is instantaneously at rest is 40 metres.
b) To find the values of t when the acceleration has a magnitude of 9 ms, we need to find the roots of equation 3t² - 18t + 15 = 0.
We can solve this equation by factoring or using the quadratic formula.
3t² - 18t + 15 = 0
(t-5)(t-1) = 0
t = 5, 1
So the values of t are 5 and 1 seconds.
c) To find the average velocity of P during the first 2 seconds, we can use the formula for average velocity:
average velocity = (distance travelled)/(time taken)
We can find the distance travelled by finding the value of s at t = 2 and t = 0 and subtracting them.
s = t³ - 9t² + 15t + 40
s(2) = 8 - 36 + 30 + 40 = 42
s(0) = 0 - 9(0)² + 15(0) + 40 = 40
distance = 42 - 40 = 2 metres
time = 2 - 0 = 2 seconds
average velocity = 2/2 = 1 m/s
d) To find the total distance travelled in the first 6 seconds, we can find the value of s at t = 6 and t = 0 and subtract them.
s = t³ - 9t² + 15t + 40
s(6) = 216 - 540 + 90 + 40 = -194
s(0) = 0 - 9(0)^2 + 15(0) + 40 = 40
distance = -194 - 40 = -234 metres
So the total distance travelled in the first 6 seconds is -234 meters.
Note that distance travelled is negative, which means that the particle is moving in the opposite direction of O.

Razi is filling bags with party favors for his birthday party. The table to the right shows the number of bags he still needs to fill after 4, 5, 6, and 7 minutes. If he is working at a constant rate, what was the initial number of party favor bags Razi had to fill?
36
48
52
56
Therefore, the initial number of party favor bags Razi had to fill is 20.
To determine the initial number of party favor bags Razi had to fill, we need to analyze the relationship between the time and the number of bags remaining.
Looking at the table, we can observe that the number of bags remaining decreases by 4 for every additional minute of work. This suggests a constant rate of filling the bags.
From the given data, we can see that at the starting time (4 minutes), Razi had 36 bags remaining. This implies that for each minute of work, 4 bags are filled.
To calculate the initial number of bags, we can subtract the number of bags filled in 4 minutes (4 x 4 = 16) from the number of bags remaining initially (36).

Lester takes a sheet of paper and makes a diagonal cut from one corner to the opposite corner, making two triangles. The cut he makes is 90 centimeters long and the width of the paper is 72 centimeters. What is the paper's length?
101.9 cm is the length of the paper.
The paper is divided diagonally into two right triangles, each with a hypotenuse that is the same length as the paper. Let's call the paper's length "x" for short.
Using the Pythagorean theorem, we know that:
\(x^2 = 72^2 + 72^2\)
Simplifying this equation, we get:
\(x^2 = 2(72^2)\\x = \sqrt{2(72^2)} = 101.9 cm\)
(rounded to one decimal place)
Therefore, the paper's length is approximately 101.9 centimeters.

Milo likes the make fruit soda when he has people over to his house. He has determined that the juice to sparkling water ratio should be 4:3. He estimates that he will want 70 cups in all. How much juice and how much sparkling water will he need for the 70 cups
To make 70 cups of fruit soda with a juice-to-sparkling water ratio of 4:3, Milo will need 40 cups of juice and 30 cups of sparkling water.
If the juice-to-sparkling water ratio is 4:3, then we can write it as 4x:3x, where x is a common factor.
Let's say Milo wants to make a total of 7x cups of fruit soda (since 4x + 3x = 7x). We know that 7x = 70 cups, so x = 10.
Therefore, Milo needs 4x = 40 cups of juice and 3x = 30 cups of sparkling water.
You will therefore need 40 cups of juice and 30 cups of sparkling water to generate 70 cups of fruit soda with a 4:3 juice-to-sparkling water ratio.

Experimental Probability Q/ During archery practise, Tom hits the target on 14 put of 20 tries. What is the experimental probability that he will hit the target on his next try? Write your answer as a fraction, decimal and percentage.
The experimental probability of an event is calculated by dividing the number of successful outcomes (in this case, hitting the target) by the total number of trials. In this scenario, Tom hits the target on 14 out of 20 tries. To find the experimental probability of hitting the target on his next try, we divide 14 by 20. The result can be expressed as a fraction, decimal, and percentage.
The experimental probability of hitting the target on the next try is found by dividing the number of successful outcomes (hitting the target) by the total number of trials. In this case, Tom hits the target on 14 out of 20 tries. Therefore, the experimental probability is:
Experimental probability = Number of successful outcomes / Total number of trials
= 14 / 20
= 7 / 10
The fraction 7/10 represents the experimental probability of hitting the target on the next try.
To express the experimental probability as a decimal, we divide the numerator by the denominator:
Decimal form = 7 / 10
= 0.7
Thus, the experimental probability can be expressed as 0.7.
To convert the decimal into a percentage, we multiply the decimal by 100:
Percentage form = 0.7 * 100
= 70%
Hence, the experimental probability of Tom hitting the target on his next try is 7/10, 0.7, or 70%.
