Answers

Answer 1

Answer: She may conclude that in her hometown, a majority of people experience greater happiness thanks to positive relationships. However, in order to apply this to a greater population, she will have to use a larger sample of people.

Answer 2

Answer: Since this is an observational study and not an experiment, she can only conclude that there may be a link between closeness with family and happiness but we cannot say that closeness with family results in happiness.

jenny went to mall with $120 in her wallet. spent $25.65 on a shirt $4.58 on a snack . how much money does she left

Answers

She started off with 120 then spent 25.65 on a shirt then 4.58 on a snack
25.65 and 4.58 are the numbers that you have to add together then subtract from 120.
so 25.65+4.58=30.28
So then you subtract 30.28 from 120 and get 89.72
She has $89.72 left over
Hope I helped :)

$89.77, you subtract both items from her total and that is what she has left in her wallet

How do you calculate the diameter of a circle?

Diameter = 2 * Radius (r) Area of the circle radius. The radius of the circle calculator uses the following area of the circle formula, Area of a circle = π * r 2

What is the area of a circle with diameter 6 centimeters?

Area = π· ( d2) 2 = 3.14· ( 62) 2 = 3.14· (3) 2 = 28.27 square centimeters (*) Area = C2 4π = 18.852 4π = 355.32(4·3.14) = 355.3212.56 = 28.27 square centimeters (*)

The first formula is A=πr², or the second formula is d=2r. Now, we could solve for a,

A=1/4πd²=1/4*π*6²=28.27433cm²,

Therefore, the solution is 28.26 cm 2
