Answer: Each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

Step-by-step explanation:

Money required = $ 842.36

Donation amount = $ 300.00

Amount left to arrange  =  (Money required - Donation amount )

= $ (842.36- 300.00)

=  $ 542.36

Number of fundraisers = 4

Money required to arrange by each fundraiser = (Amount left to arrange) ÷4

= $ (542.36÷4)

= $ 135.59

Hence, each fundraiser need to raise $ 135.59  in order to purchase the new net and equipment.

According to the manufacturer of a backup UPS device, the normal output voltage is 120 volts. The sample of 40 measured voltage
anyanavicka [17]

Answer:

z = 1.83<1.96

null hypothesis is accepted

The sample is came from a population mean

Step-by-step explanation:

<u>Step</u> :-1

The sample of 40 measured voltage amounts from a unit have a mean of 123.59 volts and a standard deviation of 0.31 volts

given sample size n =40

mean of the sample ×⁻ = 123.59 volts

standard deviation of sample σ = 0.31 volts

<u>Step2</u>:-

<u>Null hypothesis</u> :-

the sample is from a population with a mean equal to 120 volts.

H₀ : μ =120

<u>Alternative hypothesis:-</u>

H₁ : μ ≠120

<u>level of significance</u>:- α =0.05

<u>Step 3:</u>-

<u>The test statistic</u>

z = \frac{x_{-}-mean }{\frac{S.D}{\sqrt{n} } }

substitute values and simplification

z = \frac{123.59-120}{\frac{0.31}{\sqrt{40} } }

on simplification we get the calculated value

z = 1.83

The tabulated value z =1.96 at 0.05 % level of significance

<u>Conclusion</u>:-

Calculated Z < The tabulated value z =1.96 at 0.05 % level of significance

so the null hypothesis is accepted

The sample is came from a population mean

For the inequality y−x&gt;−x2−1, where is the graph shaded and is the curve solid or dotted?
vodomira [7]

The curve will be dotted and upper portion of the graph will be shaded.

<h3>Inequality expression</h3>

Inequality are expressions not separated by an equal sign Given the following inequality

y−x>−x2−1

Equate to zero

y > x^2 + x -1

Since the inequality sign in the given expression is a less than sign, hence the curve will be dotted.

Also, since the inequality sign is a "greater than", hence upper portion of the graph will be shaded.
