Answer:
Hello the answer is - 4
Step-by-step explanation:
[tex]9 = - 3 - 3r \\ 9 + 3 = - 3r \\ - 3r = 12 \\ r = \frac{12}{ - 3} = - 4[/tex]
Answer:
-4
Step-by-step explanation:
-3r-3=9
9+3=-3r
12=-3r
12/-3=-3/-3r
-4=r

Suppose 56V% of politicians are lawyers. If a random sample of size 787787 is selected, what is the probability that the proportion of politicians who are lawyers will differ from the total politicians proportion by greater than 4%4%
Answer: 0.0238
Step-by-step explanation:
Given : Proportion of politicians are lawyers: p= 0.56
Sample size : n= 787
Let [tex]\hat{p}[/tex] be th sample proportion.
The the probability that the proportion of politicians who are lawyers will differ from the total politicians proportion by greater than 4% will be :-
[tex]P(|\hat{p}-0.56|>0.04)=P(-0.04>\hat{p}-0.56>0.04)=\\\\ P(-0.04+0.56>\hat{p}>0.04+0.56)\\\\=P(0.52>\hat{p}>0.60)\\\\=P(\dfrac{0.52-0.56}{\sqrt{\dfrac{0.56(1-0.56)}{787}}}>\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.60-0.56}{\sqrt{\dfrac{0.56(1-0.56)}{787}}})\\\\=P(-2.26>z>2.26)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(-2.26<z<2.26)\\\\=1-(2P(Z > 2.26)-1)\ \ \ [P(-z<Z<z)=2P(Z > |z|)-1]\\\ =2-2P(Z > 2.26)\\\\=2-2(0.9881)=0.0238[/tex]
Hence, the required probability = 0.0238

JULIO'S DAD BOUGHT 10 DOZEN POTATOES. THE POTATOES WERE EQUALLY
DIVIDED INTO 6 BAGS. HOW MANY POTATOES ARE IN EACH BAG?
Answer:
There are 20 potatoes in each bag.

20 potatoes in each bag.
Hope this helped!
Answer:
there are 20 potatoes in each bag.
Step-by-step explanation:
One dozen is equal to 12, so you have to multiply 12 by 10 to find the number of potatoes Julio's dad bought.
12 x 10 = 120
after finding the number of potatoes bought, you have to divide the number of potatoes by the number of bags:
120 : 6 = 20

Solve tan 2x + tan x=0, for 0 < x < 2π
Answer:
Start by getting everything on the same side of the equals sign and then set it equal to 0. . Factor out the common tan^2x like this: . Now we have 2 separate equations to solve: and sinx = 0. Now we have to figure out where tan^2 is 0 between 0 and 2pi. If we include 2pi, the solutions for that equation are . You can test those out on your calculator just to be sure. There's only one value of x for the next equation. The only place between 0 and 2pi where the sin x = 1 is at x = . And there you go!

Petrolyn motor oil is a combination of natural oil and synthetic oil. It contains 5 liters of natural oil for every 8 liters of synthetic oil. In order to make 884liters of Petrolyn oil, how many liters of natural oil are needed?
9514 1404 393
Answer:
340
Step-by-step explanation:
The ratio of natural to synthetic is give as ...
5 : 8
Then the ratio of natural to total would be ...
5 : (5+8) = 5 : 13
The amount of natural oil in 884 total liters of oil will be ...
(5/13)(884 L) = 340 L
884 liters of Petrolyn oil will contain 340 liters of natural oil.
Answer:
340
