Answer:

Step-by-step explanation:

These are logically difficult, so it makes sense to me you're asking about this.

so A = 1/2 (big arc - small arc)

and 360 = big arc + small arc

then

360 - small arc = big arc

so rewrite the top equation

A = 1/2(360-small arc -small arc)

63 = 1/2( 360 - 2 small arc)

2* 63 = 360 - 2 small arc

126 = 360 - 2 small arc

2 small arc = 360-126

2small arc = 234

small arc = 234/2

small arc = 117

x = 117°

Tristan is an administrator for a private nonprofit college and read a surprising statistic that 74% of graduates from private n

STatiana [176]

Answer: $H_0: p=0.74\\\\ H_a:p$

Step-by-step explanation:

Let p be the population proportion for the graduates from private nonprofit colleges in the region had at least one outstanding student loan at the time of graduation.

Given : Tristan is an administrator for a private nonprofit college and read a surprising statistic that 74% of graduates from private nonprofit colleges in the region had at least one outstanding student loan at the time of graduation.

i.e. $p=0.74$

He believes that percentage is high and claims that the proportion of graduates at his college is less than the regional rate.

i.e. $p$

Since, the null hypothesis is a statement which always takes equal sign or generally shows " no difference " where as alternative hypothesis takes unequal signs.

Then, the null and alternative hypotheses for this hypothesis test :-

$H_0: p=0.74\\\\ H_a:p$

If p is the hypothesis of a conditional statement and q is the conclusion, which is represented by ~p → ~q?

AfilCa [17]

Conditional statement is a statement with a hypotesis and a conclusion:

If $\text{ \underline{ hypothesis } } p$ , then $\text{ \underline { conclusion } } q$ or mathematically $p\rightarrow q$ .

Converse statement of $p\rightarrow q$ is statement $q\rightarrow p$ .

If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse: $\neg p\rightarrow \neg q$ .

Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive: $\neg q\rightarrow \neg p$ .

Then,

Answer: the correct choice is D (the inverse of the original conditional statement).

11+(-3)-1/8j-3/8j+7=<br><br> Will give reward if right

zhannawk [14.2K]

Answer:

J = 7.5

Step-by-step explanation:

* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *

First, start off by adding all of the like numbers.

11 + (-3) + 7 = 8 + 7 = 15

- 1/8 j - 3/8 j = - 4/8 j.

Combining those two sums, we get:

15 - 4/8 j = 0

Subtract 15 from both sides,

-4/8 j = -15

Simplify -4/8 to -1/2, and then to -0.5

-0.5j = -15

Divide.

-15/-0.5 = 7.5

When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5

If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.
