sladkih [1.3K]

Answer:

The answer is "800"

Step-by-step explanation:

The total tax  = $ 960

Total number of days  =300

day =300

Seller credit =?

Formula:

\bold{\text{Seller credit} = \frac{\text{total tax} \times \text{number of days}}{\text{day}}}

                   = \frac{960 \times 300}{360}\\\\= \frac{32 \times 300}{12}\\\\= 8 \times 100\\\\=800

The fourth graders are helping raise money for the local animal shelter they hoped to raise 1,000. so far they have made 465 in
vredina [299]

The fourth graders raised 175 more than 1,000 for the local animal shelter.

First, let us identify the given.

  • Target value to raise= 1,000
  • Profit from bake sale= 465
  • Profit from t-shirt sales= 710

How much money did the fourth graders raise? The sum of the profit from the bake sale and t-shirt sales determines the total money raised.  

Total money= Profit from bake sale + Profit from t-shirt sales

Total money= 465 + 710

Total money= 1175

How much more than 1,000 have the fourth graders raised? This amount is equivalent to the difference between the total money raised and the target amount, 1,000.

Total money-target amount

1175-1000= 175

The sodium content of a popular sports drink is listed as 200 mg in a 32-oz bottle. Analysis of 20 bottles indicates a sample me
julia-pushkina [17]

Answer:

The sample does not contradicts the manufacturer's claim.

Step-by-step explanation:

We are given the following in the question:  

Population mean, μ = 200 mg

Sample mean, \bar{x} = 211.5 mg

Sample size, n = 20

Alpha, α = 0.05

Sample standard deviation, s = 18.5 mg

a) First, we design the null and the alternate hypothesis  for a two tailed test

H_{0}: \mu = 200\\H_A: \mu \neq 200

We use Two-tailed t test to perform this hypothesis.

b) Formula:

t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} } Putting all the values, we have

t_{stat} = \displaystyle\frac{211.5 - 200}{\frac{18.5}{\sqrt{20}} } = 2.7799

c) Now,

t_{critical} \text{ at 0.05 level of significance, 19 degree of freedom } = \pm 2.0930

Since, the calculated t-statistic does not lie in the range of the acceptance region(-2.0930,2.0930), we reject the null hypothesis.

Thus, the sample does not contradicts the manufacturer's claim.

d) P-value = 0.011934

Since the p-value is less than the significance level, we reject the null hypothesis and accept the alternate hypothesis.

Yes, both approach the critical value and the p-value approach gave the same results.

Find three positive consecutive integers such that the product of the smallest and the largest is 17 more than three times the m
trapecia [35]
There are two answers to this question
the first possible answer is 5, 6, and 7 and the second possible answer is -4, -3, and -2


Step-by-step explanation:

let the three numbers be (x-1), x, and (x+1)
the product of the smallest and largest number is 17 more than 3 times the middle number, or
(x-1)(x+1) = 3x+17, or
x^2-1 = 3+17, or
x^2-3x-18 = 0
(x-6)(x+3) = 0
So x = 6 or -3
Then just subtract one and add one to get the other integers. the three numbers are 5, 6, and 7 or -4, -3, and -2
