Answer:

The zero product property states that if ab=0 , then either a=0 or b=0.

So when it comes to factors, you may have something that looks like this:

(x-1)(x+5)=0

With the property you can know that this means that you should set each factor to 0.

x-1=0 so x=1

x+5=0 so x=-5

This gives you the 2 x-intercepts of the equation 1 and -5

I hope this helped let me know if you need anything else!

Answer:

19 (using "3.14" as pi)

18.99036781...(using pi button)

Step-by-step explanation:

Formula: C=dπ

so, (59.66)=dπ

you would divide circumference (C) by pi which will get you the answers above :)

hope this helped

Pls help and thank you lolz

Answer:

Step-by-step explanation:

there are two ways to answer : since angle 1 and the 125 degree angle are a linear pair, you can do 180-125 = 55, or, since the three angles in the triangle always add up to 180, you can do 180-37-88 = 55.

Consider the following hypothesis test H0 p 20 Ha p 20 A sample of 400 provided a sample proportion p 175 a Compute the value of

Bogdan [553]

Answer:

a) -1.25

b) 0.2112

c) -1.96

Step-by-step explanation:

Data provided in the question:

Sample size, n = 400

H0 : p = 20

$\bar{p}$ = 175

Now,

a) The test statistic is given as:

Z = $\frac{(\bar{p}-p)}{\sqrt{\frac{p(1-p)}{n}}}$

on substituting the respective values, we get

Z = $\frac{(0.175-0.2)}{\sqrt{\frac{0.2\times0.8}{400}}}$

= -1.25

b) The p-value = 2 × P(Z <-1.25)

Now from the standard normal table

P(Z <-1.25) = 10.56% = 0.1056

Thus,

p-value = 2 × 1056 = 0.2112

c) for a = 0.05,

the critical value is $Z_{\frac{a}{2}}=Z_{\frac{0.05}{2}}$ i.e $Z_{0.025}$

Now from standard normal table

$Z_{0.025}$ = -1.96
