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
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
It took him 12 mins to bike the trail because it implies that you bike faster than jogging so the time should be shorter hence bike twice as fast as jogging
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 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
