A four line classified ad costs 25 for a week. Each additional line costs 2. What is the weekly cost for a 12 line ad
faust18 [17]

Answer: 41

Step-by-step explanation:

If each line costs 2, then for the four-line ad, the cost is the initial price plus 4(2), meaning the initial cost is 25-8=17.

Thus, the cost of a 12-line ad is 17+2(12)=41

Find the indicated area under the curve of the standard normal​ distribution; then convert it to a percentage and fill in the bl
trapecia [35]

Answer:

About​ 99.74% of the area is between z = -3 and z = 3

Step-by-step explanation:

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.

Area between z = 3 and z = -3

pvalue of z = 3 subtracted by the pvalue of z = -3

z = 3 has a pvalue of 0.9987

z = -3 has a pvalue of 0.0013

0.9987 - 0.0013 = 0.9974

0.9974*100 = 99.74%

About​ 99.74% of the area is between z = -3 and z = 3

olga_2 [115]

Answer:

3 questions

Step-by-step explanation:

since he got 75% of 4, the equation should be set up as 75% times 4, or 75%*4. since 75% is equal to 0.75, replace 75% with 0.75 to get:
0.75*4
0.75*4 equals 3

The total surface area of this cuboid is 112^2
Nastasia [14]

The value of x is 3

<h3>How to solve for x?</h3>

The given parameters are:

Length = 10cm

width = 2cm

Height = x

The surface area is calculated as;

Area = 2 *(lw + lh + wh)

So, we have:

2 * (10 * 2 + 2x + 10x) = 112

Evaluate the like terms and divide by 2

20 + 12x = 56

Subtract 20 from both sides

12x = 36

Divide by 12

x = 3

hence, the value of x is 3
