Option A is correct

1) we calculate the volume of the first carton:

volume=length x width x height

volume=3 ft * 2 ft * 2 ft=12 ft³

Therefore:

A machine can fill 12 ft³ in 3 seconds.

2) we calculate the volume of the second carton.

volume=length x width x heigth

volume=4 ft * 5 ft * 6 ft=120 ft³

3) we calculate the time that the machine needs for fill the second carton with packing material by the rule of three.

12 ft³---------------------3 seconds

120 ft³--------------------      x

x=(120 ft³ * 3 seconds) / 12 ft³=30 seconds.

answer: 30 seconds.

Answer:

13<X<17

Step-by-step explanation:

Triangular Inequalities state that a side is always greater than the absolute value of the difference of the other two sides and less than the sum of the other two sides. You use the inequality |a-b|<c<a+b with a, b, and c as the lengths of the sides.

When you plug in the numbers, (X being c, 2 being b, and 15 being a) you get

|15-2|<X<15+2

|13|<X<17

Which brings us to our final answer of:

13<X<17

Step-by-step explanation:

::::::::::::::::

The probability of the number on the upward face is not 4 would be 11/12 or 0.92 by calculating as follows:

Solution:

The possible outcomes for rolling a dodecahedral die, numbered from 1 to 12, once is given below in the term of sample space S:

S = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12}.

Therefore,

n(S) = 12

Event A: Sample space in the case of not having number 4 on the upward face:

A = {1, 2, 3, 5, 6, 7, 8, 9, 10, 11, 12}

therefore,

n(A) = 11

the required probability = \(\dfrac{\text{Number of times event A, occurred}}{\text{Number of times this experiment performed}}\)

then putting the space values here;

 = \(\frac{n(A)}{n(S)}=\frac{11}{12}=0.92\)

Thus, the required probability is 0.92

Hey there! I'm happy to help!

To find the volume of a cube, you simply take whatever the side length is and multiply it by itself 3 times, which is also known as cubing the number!

16×16×16=4096

You can also write it as 16³=4096

This is because the length is 16, the width is 16, and the height is 16, so you multiply them all together!

What is a quadratic equation?

A quadratic equation is a second-order polynomial equation with a single variable such as x, where ax²+bx+c=0. with a ≠ 0 . Given that it is a second-order polynomial equation, the algebraic fundamental theorem ensures that it has at least one solution. Real or complicated solutions are both possible.

(a)

At the beginning when the ball leaves the hand of the child, the horizontal distance was 0, so putting x=0 we can get the height of the ball.

at time zero, t=0, the distance is 5 feet, so the ball is at 5 feet height

(b)

the max occurs at the average of the solutions, which is 28.

or -b/2a = -6/(2*-1/14) = -6/ (-1/7) = 42 ft

-(1/14)*42^2 +6*42 + 5 = 131

so the max height is 131 feet after 42 feet

(c)

(-1/14) x^2 + 6x + 5 =0

x^2 - 84x - 70 = 0 <--- after multiplied by -14

x = 84.825, x = -0.825

the ball will hit the ground at (56 + sqrt(3416)) / 2 = 84.825 ft

I think it is 1 in 12 ft.

Step-by-step explanation:

If the brain volumes (cm³) of 20 brains have a mean of 1085.2 cm³ and a standard deviation of 125.6 cm³. For such data: it is significantly low for a brain because 1386.4 cm³ is less than the upper limit.

Mean = 1085.2 cm³

Standard deviation = 125.6 cm³

Hence,

Lower limit = Mean - 2 x Standard deviation

Lower limit  =1085.2 - 2 x 125.6

Lower limit =1161.2 - 251.2

Lower limit  =910

Upper Limit = Mean + 2 x Standard deviation

Upper Limit = 1161.2 +  2 x 125.6

Upper Limit =1161.2 +251.2

Upper Limit =1412.4

The limit of values is from 910 to 1412.4.

A value below 910 will be is considered low and a value above 1412.4  will be considered high

Therefore 1386.4 cm³ is less than the upper limit. Thus it is significantly low for a brain.

A 95% confidence interval for the mean price for all the TI-84 Plus calculators being sold on Amazon.(91.44, 155.44)

A confidence interval, in statistics is defined as the probability that a population parameter will fall between a set of values for a certain proportion of times. Analysts often use confidence intervals that contain either 95% or 99% of expected observations.

Now, the empirical rule is the formula:

CI = μ ± nσ

Where:

μ is mean

σ is standard deviation

n is number of standard deviations from the mean

A confidence level of 95% is 2 standard deviations from the mean

Thus:

CI = 123.44 ± 2(16)

CI = (91.44, 155.44)

Caludia needs to pay 2917.6128 as a payment of compound interest capital+interest.

What is compound interest?

compound interest is interest on principal + interest and this denotes to the addition of interest to the principal amount of a loan or deposit.

Capital(p) = $6400

Rate of interest(r) = 11%

Years(n) = 3

The general formula of compound interest is \(A= p(1+\frac{r}{100}})^n\).

Now

\(A= 6400(1+\frac{11}{100}})^3\\A=6400 \times \frac{111}{100} \times \frac{111}{100} \times \frac{111}{100}\\A= 8752.8384\)

The entire amount (Capital+interest) is equal to $8752.8384.

If we take 1 year as a period then Claudia needs to pay \(\frac{8752.8384}{3}\\=2917.6128\)

Therefore, Claudia needs to pay 2917.6128 as a payment of compound interest capital+interest.

Answer: 23 1/3

Step-by-step explanation:

y = 1/2x + 1 is the line's equation in slope-intercept form.

The equation of a line in slope intercept form is expressed as y = mx + b where:

m is the slope

b is the y-intercept

Given the following coordinate points (4, 3) and (0, 1), the slope is calculated as:

Slope = 1-3/0-4
Slope = -2/-4
Slope = 1/2

For the y-intercept, it is the point where the x-coordinate is zero, hence the y-intercept if (0, 1)

Determine the required equation
y = mx + b

y = 1/2x + 1

Hence the equation of the line in slope-intercept form is y = 1/2x +1

Answer:

The probability is 0.58992 or simply 0.59

Step-by-step explanation:

We start by getting the z-scores of the diameter

we have this as follows;

Mathematically;

z-score = (x-mean)/SD

mean = 9.0 mm

SD = 1.5 mm

For 8.00 mm, we have

z = (8-9)/1.5 = -0.67

For 10.5 mm, we have

z = (10.5-9)/1.5 = 1

So the probability we want to calculate is;

P( 1 < x < -0.67)

we can calculate this using the standard normal distribution table

We have this as ;

P( x < -0.67) - P( x > 1) = 0.58992
