(6.72×10^9)÷(3.2×10^2)=2.1×10^7
6.72÷3.2=2.1 and
10^9÷10^2=10^7 {here power is subtracted 9-2=7}
2.1×10^7
Answer:
there are 4 terms
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given that a marketing research firm is estimating which of two sodas (A or B) college students prefer.
Sample size of 75 was taken at random.
Since sample size is sufficiently large i.e. >30, and also since samples are taken at random, we can assume that sample proportion
p= follows a normal distribution with mean = 0.6 and variance = npq = 75(0.6)(0.4)
Yes, this sample is large enough to calculate a confidence interval.
We have 1 square with side length 8 inches, and 4 triangles with a base length of 8 inches and a height of 15.
Surface area = (8 × 8) + 4(0.5 × 8 × 15)
The first part of this equation is the area of the square
The second part is the area of a triangle, multiplied by 4 (because there are 4 triangles)
= 64 + 4(60)
= 64 + 240
= 304 in²
The total surface area is 304 square inches.

In the coordinate plane, the length of the line segment that connects points at (0, -1) and (-7, -2) is 7.07 units.
<u>Step-by-step explanation:</u>
Here we have ,in coordinate plane we are given two points (0,-1 ) & ( -7,-2 ).
From Straight line concept, we know that Distance between any two pints in a plane i.e distance between points and is given by:
, Here = and =
Putting values in above formula we get:
⇒
⇒
⇒
=
∴In the coordinate plane, the length of the line segment that connects points at 0, -1 and. -7, -2 is .
