5 or $25 for every mile you run. However, you cannot have more than 100 people sponsoring you for this marathon.
Now, create a system of inequalities using the above information (use x and y as the variables).

  • x + y ≤ 100
  • 15(x) + 25(x) ⩾ $1500

Let the people paying $15 be "x" and $25 be "y"

<u>1st inequality</u>

15(x) + 25(x) ⩾ $1500

<u>2nd inequality</u>

x + y ≤ 100

Answer:

See below ~

Step-by-step explanation:

<u>Let</u> :

  • x = people donating $15 when you run
  • y = people donating $25 when you run

<u>Two inequalities created are</u> :

  • 15x + 25y ≥ 1500
  • 3x + 5y ≥ 300 [Simplified] ⇒ Inequality 1
  • x + y ≤ 100 ⇒ Inequality 2

<u>Solving</u>

A rectangle has a perimeter of 269.4 miles and a base of 77.6 miles. What is the height?
pantera1 [17]

Answer:

57.1

Step-by-step explanation:

Perimeter Formula: P = 2l + 2w

Simply plug in what we know and solve:

269.4 = 2l + 2(77.6)

269.4 = 2l + 155.2

114.2 = 2l

l = 57.1

A local company wants to evaluate their quality of service by surveying their customers.
stich3 [128]

Answer: b. 0.98

Step-by-step explanation:

The formula to find the maximum error of the estimated mean :

E=z^*\dfrac{\sigma}{\sqrt{n}}            (1)

, where \sigma = standard deviation

n= Sample size

z* = Critical z-value.

As per given , we have

\sigma=5

n=100

Critical value for 95% confidence interval = z*=1.96

Put these values in the formula (1), we get

E=(1.96)\dfrac{5}{\sqrt{100}}

E=(1.96)\dfrac{5}{10}=0.98

Hence, the maximum error of the estimated mean quality for a 95% level of confidence is 0.98.

Therefore , the correct answer is b. 0.98 .
