Given

$y = 25x$

Required

Cost of 3 cubic yards -- Missing from the question

The required means that: $x = 3$

Plug in $x = 3\\$ to $y = 25x$

$y = 25 * 3$

$y = 75$

Answer:

What is the probability the mean of his sample will be between $70.00 and $80.00? = 64/64 =1

s1) = 99% =z score = 127/128

s2)64/64 = 1

s3)95% of 64 = 123/128

s4) p) step 3 = 95% of 64 = 60.08 /64 = 60/64 = 93.75%

s5) P)of 2+4 = 283/292 = 96.92%

Find the median, first quartile, third quartile, and interquartile range of the data.

telo118 [61]

Answer:

Median: 189.5

First quartile: 181.5

Third quartile: 203.75

Interquartile Range: 22.25

Step-by-step explanation:

To find the median, first quartile and third quartile we need to organize the data as:

157, 181, 183, 189, 190, 203, 204, 212

Now, the position of the median is calculated as:

$PosM = (n+1)*\frac{1}{2}$

Where n is 8, so replacing we get:

$PosM = (8+1)*\frac{1}{2}=4.5$

So, the median can be calculated as:

Median = 0.5(189) + 0.5(190) = 189.5

Because 189 is in the fourth position and 190 is in the first position.

At the same way the position for the first and third quartile is:

$PosQ1 = (n+1)*\frac{1}{4}= (8+1)*\frac{1}{4}=2.25\\PosQ3 = (n+1)*\frac{3}{4}= (8+1)*\frac{3}{4}=6.75$

Then, the first and third quartile is equal to:

Q1 = 0.75(181) + 0.25(183) =181.5

Q3 = 0.25(203) + 0.75(204) = 203.75

Where 181 is in the second position, 183 is the third position, 203 is the sixth position and 204 is the seventh position.

Finally, the interquartile range is calculated as:

Q3 - Q1 = 203.75 - 181.5 = 22.25

dr. glock had an average balance of $400 on her credit card account for one year. She paid 1.75% interest per month. how much

Mariana [72]

x = interest paid altogether

400 + 400(0.175) = x

The 400 comes from the average balance. 400(0.175) comes from the interest she has to pay each month. 1.75% as a decimal is 0.175. It's multiplied since she pays 1.75% of the average balance.
