Answer:
0.36878
Step-by-step explanation:
Given that:
Mean number of miles (m) = 2135 miles
Variance = 145924
Sample size (n) = 40
Standard deviation (s) = √variance = √145924 = 382
probability that the mean of a sample of 40 cars would differ from the population mean by less than 29 miles
P( 2135 - 29 < z < 2135 + 29)
Z = (x - m) / s /√n
Z = [(2106 - 2135) / 382 / √40] < z < [(2164 - 2135) / 382 / √40]
Z = (- 29 / 60.399503) < z < (29 / 60.399503)
Z = - 0.4801364 < z < 0.4801364
P(Z < - 0.48) = 0.31561
P(Z < - 0.48) = 0.68439
P(- 0.480 < z < 0.480) = 0.68439 - 0.31561 = 0.36878
= 0.36878
Answer:
Step-by-step explanation:
Michael and Juanita are interested in the amount of sand required to build a sand pyramid of the size that they see while at a sand sculpture exhibit. They carefully measure the width of the square base of the sand pyramid which is 4 feet and the height of the pyramid which is 5 feet. How much sand is required to build this sand pyramid?
Answer:
yellow
Step-by-step explanation:
Answer:
y-24=m(x--4)
Step-by-step explanation:
point slope form:
y-y₁=m(x-x₁)
1) find the slope or "m" first:
slope formula: (y2-y1)/(x2-x1)
(-53-24)/7+4
-77/11=-7
slope=-7
so
y-y₁=-7(x-x₁)
y1=24
x1=-4
y-24=m(x--4)
hope this helps!
- <u>To visualize 5.3</u><u>7</u><u> more accurately, divide line segment between 5.37 and 5.38 in ten equal parts. 5.3</u><u>7</u><u> lies between 5.377 and 5.378.</u>
- <u>Again </u><u>use </u><u>divide</u><u> above portion between 5.377 and 5.378 into 10 equal parts, which shows 5.3</u><u>7</u><u> is located closer to 5.3778 than to 5.3777</u><u> </u><u>so </u><u>we </u><u>can </u><u>get </u><u>the </u><u>answer</u>
<h2><u>hope</u><u> it</u><u> helps</u></h2>
