James works in a sporting goods store and earns $324 a week and 5% of his sales. One week James earned $432. What were his sales

Bogdan [553]

Answer:

His sales that week were $2,160.

Step-by-step explanation:

First, you have to subtract $324 from the amount he earned that week, to find the 5% he got from sales:

$432-$324=$108

Now, you know that he received $108 that represent 5% of his sales and you can use a rule of three to find the amount that represents 100% which would be his sales that week:

5% → 108

100% → x

x=(100*108)/5=2160

According to this, the answer is that his sales that week were $2,160.

There is no solution to the equation cscx=0.<br> True or False

Svetradugi [14.3K]

Answer:

True

Step-by-step explanation:

First, we need to recognize that

$csc(x)=\frac{1}{sin(x)}$

Now, we can try to solve

$\frac{1}{sin(x)} =0$

Multiply each side by $sin(x)$

$1=0*sin(x)\\\\1=0$

As we end up with an answer that cannot be true, we know that there is no solution.

Another method to solve this would be graphing the function $y=csc(x)$

When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.

LINEAR MODELS (functions)

That question mark is filled in with the y-intercept. The y-intercept is where the graph goes through the y-axis. Our graph goes through the y-axis at 1, so the equation is y = 4x + 1

An apple farm claims that the average weight of all their apples is 8oz. A sample of 20 apples were picked that had a mean of 7.

Nimfa-mama [501]

Answer:

The mean apple weight is different from 8oz

Step-by-step explanation:

Claim : An apple farm claims that the average weight of all their apples is 8oz.

$H_0:\mu \neq 8\\H_a:\mu = 8$

n = 20

Standard deviation =s = 0.95

Since n < 30

So we will use t-test

x = 7.77

$t =\frac{x-\mu}{\frac{s}{\sqrt{n}}}$

Substitute the values :

$t =\frac{7.77-8}{\frac{0.95}{\sqrt{20}}}$

$t =−1.0827$

Since we are not given the significance level

So, we will take 5%

So,α = 0.05

Degree of freedom = df = n-1 = 20-1 = 19

So, using t table

$t_{\frac{\alpha}{2} , df}=2.093$

Since t critical > t statistic

So, we accept the null hypothesis.

So, The mean apple weight is different from 8oz
