Answer:im pretty sure its 84

Step-by-step explanation:a=(axb)/2

a=(7x24)=168/2=84

2(3u-8)= 38

6u-16=38

take 16 on the other side..

6u = 38 +16

6u = 54

u = 9

Answer:

u=9

Step-by-step explanation:

Divide both sides by 2

3u-8=19

Add 8 to both sides

3u=27

divide both sides by 3

u=9

Answer:

The theoretical probability of choosing a letter other than Z is 96.2%

Step-by-step explanation:

Answer:

Step-by-step explanation:

From the given information.

An ordinal scale measurement does not give room to know the actual difference that coexists between the two measurements in a variable but in an interval scale of measurement, it is possible to deduce the actual difference that coexists between the two measurements in a variable.

Similarly, the ordinal scale only shows the rank of observations as per size and magnitude but in case of interval scale, it consists of classes with equal size, differentiated into direction and magnitude.

Answer:

36.49 and 35.49

Step-by-step explanation:

Let the two consecutive number be x-1 and x

If their product is 1295, then;

x(x-1) = 1295

x² - x = 1295

x²-x - 1295 = 0

x = 1±√(-1)²-4(-1295)/2

x = 1±√1+5180/2

x = 1±71.98/2

x = 72.98/2

x = 36.49

x - 1 = 35.49

Hence the two numbers are 36.49 and 35.49

Answer:

133 pieces of 15cm can be cut from the ribbon.

Step-by-Step Explanation:

Length of ribbon = 20 meters

Length needed to be cut = 15 cm

We will convert meters into centimeters.

1 meter = 100 cm

20 meters = 2000 cm

Number of pieces = [tex]\frac{2000}{15}[/tex]

Number of pieces = 133.33

Rounding off to nearest whole number = 133

Hence,

133 pieces of 15cm can be cut from the ribbon.

Elissa can cut 133 ribbons from 20 meters long ribbon and this can be determined by using the unitary method.

Given :

Elisse has 20 meters of ribbon.

The following steps can be used to determine the total number of ribbons of length 15 cm can be cut from 20 meters ribbon:

Step 1 - Remember 1 meter is 100 cm.

Step 2 - If 1m is 100 cm then 20m is equal to:

[tex]=20\times 100[/tex]

= 2000 cm

Step 3 - Elisse cut 15cm long ribbon. So, the total number of ribbons she can cut is:

[tex]=\dfrac{2000}{15}[/tex]

Simplify the above expression.

= 133.334

[tex]\approx[/tex] 133

So, she can cut 133 ribbons from 20 meters long ribbon.

Answer:

The standard deviation of the age of the customers was of 2.08 years.

Step-by-step explanation:

Problems of normally distributed samples can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

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 pvalue, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu = 24[/tex]

85% of the customers are between the ages of 21 and 27 years.

Since the normal distribution is symmetric, this means, for example, that 27 is the 50 + (85/2) = 92.5th percentile, that is, when [tex]X = 27[/tex], Z has a pvalue of 0.925. So when [tex]X = 27, Z = 1.44[/tex]. We use this to find [tex]\sigma[/tex]

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.44 = \frac{27 - 24}{\sigma}[/tex]

[tex]1.44\sigma = 3[/tex]

[tex]\sigma = \frac{3}{1.44}[/tex]

[tex]\sigma = 2.08[/tex]

The standard deviation of the age of the customers was of 2.08 years.

Step-by-step explanation:

a slope is just a rise ofver run from one dot to anothor so you go up 1 and over 4 and if you dont do the 2 dots that are closest to each other you have to simplify you r exspresion you will always get 1/4 on this graph

Answer:

y + 6 = 3/5(x - 4)  

Step-by-step explanation:

Point-slope is the general form y-y₁=m(x-x₁)

y1 = -6, x1 = 4

y - (-6) -> y +6

y +6 = 3/5(x - 4)

C. 3 5/18

Step-by-step explanation:

What we know:

Joel purchased 5 7/9 lb of grapes, while Jim purchased 2 1/2 lb.

What we need to find out:

How many more pounds of grapes does Joel have than Jim.

What we need to do:

Subtract 2 1/2 from 5 7/9.

But first, we need a common denominator.

2 and 9 don't have any common factors so multiply normally.

2 * 9 = 18

5 7/9 becomes 5 14/18, and 2 1/2 becomes 2 9/18.

Now to subtract.

(5 - 2) + ((14-9)/18)

3 + ((14-9)/18

3 + 5/18

Joel has 3 5/18 more pounds of grapes than Jim, so the answer is C.

Answer:

C

Step-by-step explanation:

5 7/9 - 2 1/2 = 5 14/18 - 2 9/18 = 3 5/18

Answer:

267.5 miles

Step-by-step explanation

65×2.5=162.5                

70×1.5=105

162.5+105=267.5

To solve this equation, first get rid of the fractions.

We do this by multiplying both sides by the denominator, 2.

So we have (2)(1/2s) = (7/2)(2).

On the left, we have s and on the right, we have 7.

So we have s = 7.
