Answer:

77% and as a fraction it would be 77/100

Step-by-step explanation:

0.77 is a decimal that is in the hundredths place so you already know that it'll be 77% right away then for the fraction you would just put it over 100 but since 77 is an uneven number you cannot simplify it otherwise you would.

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as ed

lord [1]

Answer:

Number of books = 4480.

Step-by-step explanation:

Given that fixed cost = $45920

Given that variable cost = $11.25 per book

Let number of books = x

then cost equation is given by 11.25x + 45920

Given that selling price of 1 book = $21.50

then selling price is given by 21.50x

Now we need to find about how many books must the publisher produce and sell so that the production costs will equal the money from sales.

So let's set both equal

21.50x = 11.25x + 45920

21.50x - 11.25x = 45920

10.25x = 45920

x = 45920/10.25

x = 4480

Hence number of books = 4480.

Express the null hypothesis and the alternative hypothesis in symbolic form. Use the correct symbol ( mu μ, p, sigma σ) for

ella [17]

Answer:

Null hypothesis: $H_0:\; \mu = 48\; ^\circ\rm F$ .

Alternative hypothesis: $H_1:\; \mu \ne 48\; \rm ^\circ F$ .

Step-by-step explanation:

In hypothesis testing, the alternative hypothesis $H_1$ represents the claim that is being tested. According to the claim in this question, the true (population) mean $\mu$ is "incorrect," or not equal to (" $\ne$ ") the proposed value of $48\; \rm ^\circ F$ . Hence, the alternative hypothesis for this question would be $H_0:\; \mu \ne 48\; \rm ^\circ F$ .

On the other hand, the null hypothesis represents what happens when that claim is disproved; it should always use the equal sign (" $=$ ".) In this question, that's the same as saying that the (population) mean $\mu$ is indeed equal to $48\; \rm ^\circ F$ . Hence, the null hypothesis for this question would be: $H_1:\; \mu = 48\; \rm ^\circ F$ .

It is SAS because
1) it is given that sides are equal (AB=CD)
2)it is also given that angles B and C are equal
3) BC is a common side so it is equal in both triangles.
