There is a 4-foot fence that surrounds your backyard. The fence casts a shadow that is 5 feet long. If you are 6 feet tall and s

Strike441 [17]

My shadow would be 7 feet tall.

Since I am standing next to the fence, then whatever difference its actual height and its shadow has, will be the same difference of my shadow to my actual height.

fence: Actual height - 4 ft ; Shadow height - 5 ft; difference - 1 ft
me : Actual height - 6 ft : Shadow height - ? ; difference - 1ft

Shadow Height - Actual Height = 1 ft
Sh - 6ft = 1ft
Sh = 1ft + 6ft
Sh = 7ft

HELP ME ASAP. The answer is -10 but explain it how to do it step by step. -6+(-30) divided by 5-(-2)

Alex777 [14]

Step-by-step explanation:

Following the order of operations we would first divide -30 by 5 which would give us -6

-6 + (-30) ÷ 5 - (-2)

From here we can add -6 + -6 = -12

-6 + (-6) - (-2)

When subtracting a negative number, the two negatives changes it to a positive. (-12) - (-2) = (-12) + 2 which would give us -10

(-12) - (-2) = -10

~Hope this helps!~

Calvin thinks a certain potato chip maker is putting less product in their personal-sized bags of chips. In the past, these bags

Strike441 [17]

Answer:

a) There are no evidence that Calvin is correct.

b) There are evidence that Calvin is correct.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 1 ounce

Sample size, n = 23

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 1\text{ ounce}\\H_A: \mu < 1\text{ ounce}$

P-value = 0.086

a) Significance level = 5% = 0.05

Since

P-value > Significance level

We fail to reject the null hypothesis and accept it. Thus, the chips bag contain one ounce of product. Thus, there are no evidence that Calvin is correct.

b) Significance level = 10% = 0.10

Since

P-value < Significance level

We reject the null hypothesis and accept the alternate hypothesis. Thus, the chips bag contain less than one ounce of product. Thus, there are evidence that Calvin is correct.
