Step-by-step explanation:

The equation that shows the relationship between r and w is r = w + 12 and 12 + w = r

An equation is an expression that shows the relationship between two or more numbers and variables.

Let r represent the number of minutes Diana runs and w represent the number of minutes she lifts weight.

Since Diana always spends more minutes running than lifting weights. Hence:

r = w + 12

The equation that shows the relationship between r and w is r = w + 12 and 12 + w = r

Answer:

The coins are picked without replacement.

The probability of picking at least one Canadian quarter is 1 minus the probability of picking 6 U.S. quarters:

\(1 - ( \frac{41}{50} )( \frac{40}{49} )( \frac{39}{48} )( \frac{38}{47} )( \frac{37}{46} )( \frac{36}{45} ) \)

\( = 1 - .28296 = .71704\)

So the probability of picking at least one Canadian quarter is about 71.7%.

Answer:

0.733

Step-by-step explanation:

Using a calculator or table:

P(-1.32 < Z < 0.94) = P(Z < 0.94) − P(Z < -1.32)

P(-1.32 < Z < 0.94) = 0.8264 − 0.0934

P(-1.32 < Z < 0.94) = 0.733

Answer:

a = -10

Step-by-step explanation:

Simplifying

7 + 4(2a + 15) = -13

Reorder the terms:

7 + 4(15 + 2a) = -13

7 + (15 * 4 + 2a * 4) = -13

7 + (60 + 8a) = -13

Combine like terms: 7 + 60 = 67

67 + 8a = -13

Solving

67 + 8a = -13

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '-67' to each side of the equation.

67 + -67 + 8a = -13 + -67

Combine like terms: 67 + -67 = 0

0 + 8a = -13 + -67

8a = -13 + -67

Combine like terms: -13 + -67 = -80

8a = -80

Divide each side by '8'.

a = -10

Simplifying

a = -10

Question One:A positive z-score indicates that the raw score is above the mean, while a negative z-score indicates that the raw score is below the mean.

Question Two: , the raw score is relatively lower than the mean.

If a raw score corresponds to a z-score of 1.75, it tells us that the raw score is 1.75 standard deviations above the mean of the distribution. In other words, the raw score is relatively higher than the mean. The z-score provides a standardized measure of how many standard deviations a particular value is from the mean.

A positive z-score indicates that the raw score is above the mean, while a negative z-score indicates that the raw score is below the mean.

Question Two:

If a raw score corresponds to a z-score of -0.85, it tells us that the raw score is 0.85 standard deviations below the mean of the distribution. In other words, the raw score is relatively lower than the mean. The negative sign indicates that the raw score is below the mean.

To understand the meaning of a z-score, it is helpful to consider the concept of standard deviation. The standard deviation measures the average amount of variability or spread in a distribution. A z-score allows us to compare individual data points to the mean in terms of standard deviations.

In the case of a z-score of -0.85, we can conclude that the raw score is located below the mean and is relatively lower compared to the rest of the distribution. The negative z-score indicates that the raw score is below the mean and is within the lower portion of the distribution. This suggests that the raw score is relatively smaller or less than the average value in the distribution.

By using z-scores, we can standardize and compare values across different distributions, allowing us to understand the position of a raw score relative to the mean and the overall distribution.

Answer:

Number of black counters = 5

Step-by-step explanation:

Let,

x be the total number of counters

Number of red counters = \(\frac{1}{3}x\)

Number of black counters = \(\frac{1}{6}x\)

Number of green counters = 15

Now,

Red counters + Black counters + Green counters = Total counters

\(\frac{1}{3}x+\frac{1}{6}x+15=x\\\\\frac{2x+x+90}{6}=x\\\\3x+90 = 6x\\90 = 6x-3x \\90 = 3x\\3x = 90\)

Dividing both sides by 3

\(\frac{3x}{3}=\frac{90}{3}\\x=30\)

Number of black counters = \(\frac{1}{6}*30\) = 5

Hence,

Number of black counters = 5

Step-by-step explanation:

Add the values

x - y = 6

x + y = 2

-------------

2x = 8

--------------

Substitute for x

2x = 8

x = 8/2

x = 4

insert x = 4 into equation x - y = 6

x - y = 6

4 - y = 6

-y = 6 - 4

-y = 2

-y/-1 = 2/-1

y = -2

∴ y = -2 , x = 4

Step-by-step explanation:

The number of fidgets and pop bought was 15 each

From the information given, we have that;

1 fidget costs $3

1 Pop cost $4

Let the number of Fidgets be x

Let the number of Pop be y

Then, we have that a total of 20 fidgets and Pop cots $75

We have that;

20x + y = 75

Now, substitute the value of x as 3, we get;

20(3) + y= 75

expand the bracket

y = 75 - 60

y = 15

The number of fidgets is expressed as;

20x/4 = 20(3) /4 = 15

Step-by-step explanation:

Answer:

Step-by-step explanation:

First we compute \(9^n\), for \(n = 0,1,2,3,4,5\)

\(9^0=1,9^1=9,9^2=81,9^3=729,9^4=6561,9^5=59049\)

We have the unit digit of \(9^n\), is either 1 or 9

Therefore, the conjecture can be state as follows

Conjecture; the unit of digit of \(9^n\), is 1, when n is even and 9 when n is odd

Let the property p(n) be the formula;

"The unit digit of \(9^n\), is 1 when n is even and 9 when n is odd"↔ P(n)

To show p(n) is true , we will use strong mathematical inductive

Show tgat p(0) and p(1) are true

We have  to show the unit digit of \(9^0\) is 1 and \(9^1\) is 9

Since any integer with zero power is one and hence

\(9^0=1\) and \(9^1 = 9\)

Therefore, p(0) and p(1) are true

Show that for al integer \(k\geq 1\), if  p(i) is true for all integer i from o through k, then p(k+1) is also true

let k be any integer with \(k \geq 1\) and suppose that for all integer i with \(0 \leq i \leq \leq k\)

the unit digit of \(9^i\) is 1 when is even and 9 when n is odd

we must show that \(9^{k +1}\) equals 1 when n is even and 9 when n is odd

Case I; (k +1 is odd)

in this case k is even and so, by inductive hypothesis, the unit digit of \(9^k\) is 1 and hence there is some non negative integer q such that

\(9^k = 10q + 1\)

now, \(9^{k+1}=9^k(9)\)

= (10q + 1)9

= 90q + 9

= 10.9q + 9

Note that for any non negative integer q , 9q is also an integer and this implies the unit digit of \(9^{k+1}\) is 9

Case II

(k +1 is even)

in this case k is odd and so, by inductive hypothesis, the unit digit of \(9^k\) is 9 and hence there is some non negative integer q such that

\(9^k=10q+9\)

Now,

\(9^{k+1}=9^k.9\\=(10q+9)9\\=90q+81\\=10(9q+8)+1\)

Note that any non negative integer q, 9q + 8 is also an integer and this implies the unit of \(9^{k+1}\) is 1

Since we have proved both the basis and the inductive step of the strong mathematical induction, we conclude that the given statement is true

Gianna is 90 miles far away in 3 hours of driving.

She drove in total of 180 minutes.

The speed can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.

Given,

Gianna drives 5 miles in 10 minutes

Speed per minute = 5/10 = 0.5 miles/minute

Gianna drove in total for 3 hours

1 hour = 60 minutes

3 hours = 60 × 3 = 180 minutes

Distance Gianna drove in 180 minutes = speed per minute × time

                                                                = 0.5 × 180

                                                                = 90 miles

Hence, Gianna drove 90 miles in 3 hours, 180 minutes is total time she drove.
