I want to know what g is

MAVERICK [17]

Answer:

Step-by-step explanation:

2(5-4g) + 3g - 11 = 5(g-3) - 12 - 3g (remove the parantheses)

10 - 8g + 3g - 11 = 5g - 15 - 12 -3g (Calculate and collect like terms)

-1 - 5g = 2g - 27 (move the terms)

-5g -2g = 27 + 1 (collect like terms and calculate)

-7g = -26 (divide both sides)

so G = 26/7

Out of the 120 students at a summer camp, 72 signed up for canoeing. There were 23 students who signed up for trekking, and 13 o

Virty [35]

Approx - 10%

72 students signed up for canoeing + the 23 students who signed up for trekking + the 13 students who signed up for both = 108 students

there are 120 students total, so you have to subtract 120 - 108 = 12

Now to find the percentage, you have to divide the number of students who didn't sign up for either, by the total

which is .1 = 10/100 = 10%

A company spends 13% of its month budget on rent which total $2600 which proportion can be used to calculate the company’s total

yaroslaw [1]

Answer:

20,000

Step-by-step explanation:

We can create a proportion to find the total budget. A proportion is an equation where two ratios are set equal to each other. We create two fractions using the budget and percents.

$\frac{13}{100} =\frac{2600}{x}$

We begin solving by cross multiplying numerator to denominator of each fraction.

$13(x)=100(2600)\\13x=260000\\\frac{13x}{13}=\frac{260000}{13} \\20,000=x$

The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 1

melomori [17]

By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19

<h3>What is standard deviation?</h3>

Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean), or expected value

Here given that

The owners of an eyeglass store claim that they fill customers' orders, on average, in 60 minutes with a standard deviation of 15. 9 minutes. Based on a random sample of 40 orders, a reporter determines a mean order time of 63 minutes

mean=μ=60

standard deviation=σ=15.9

number of sample=n=40

$\bar{x}=63 \\$

Now we can calculate z by z-score formula as

$z=\frac{\bar{x}-\mu}{\frac{\sigma}{\sqrt{n}}} \\\\&=\frac{63-60}{\frac{15 \cdot 9}{40}} \\ \\=\frac{3}{2.5140} \\ \\=1.19\end{aligned}$

By applying z-score formula we got that if a reporter determines a mean order time of 63 minutes then value o Z is 1.19
