Research in March 2019 suggests that 40% of U.S. Adults approve of way President Trump is running the country. We randomly sample 50 U.S. Adults and find that 35% approve of way President Trump is running the country. What is the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion? (Round standard error to 2 decimal places before calculating Z. Round Z to 2 decimal places before using the Normal Distribution Calculator.) Group of answer choices about 0.24 about 0.76 about 0.48
Answer:
The probability is [tex]P( \^ p < 0.35)= 0.2388 [/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is p = 0.40
The sample size is n = 50
Generally the standard error is mathematically represented as
[tex]\sigma_{\= p} = \sqrt{\frac{p * (1- p)}{n} }[/tex]
=> [tex]\sigma_{\= p} = \sqrt{\frac{0.40 * (1- 0.40)}{50} }[/tex]
=> [tex]\sigma_{\= p} = 0.07[/tex]
Generally the probability that a random sample of 50 U.S. Adults has less than 35% with this opinion is mathematically represented as
[tex]P( \^ p < 0.35) = P(\frac{\^ p - p}{\sigma_{\= p}} < \frac{0.35 - 0.40}{0.07} )[/tex]
Generally [tex]\frac{\^ p - p}{\sigma_{\= p}} = Z (The \ standardized \ value\ of \ \^ p )[/tex]
=> [tex]P( \^ p < 0.35)=P(Z < -0.71)[/tex]
From the z table
[tex]P(Z < -0.71) = 0.2388[/tex]
So
[tex]P( \^ p < 0.35)= 0.2388 [/tex]

Answer:
70
Step-by-step explanation:
im pretty sure (i did it in my head) if its wrong im sorry :/
70 because you cut down the number by half to 14 and multiply by 5 to get 70.
solve the equation:
6x = x^2+ 19
Answer:
as below
Step-by-step explanation:
6= x^2 + 19
x^2=6-19
x^2 = - 9
sqrt ( x^2) = sqrt (-9) :o sqrt of a negative? yes.. use i for the negative.. this is a complex number .. hope you've been studying those
x = i* sqrt (9)
+- x = i3 so there are technically two answers
x=i3
and -x=i3 often times the negative answer makes no sense.. so you discard it
A figure with 4 sets of parallel sides is graphed on a grid. The figure is then rotated 90 degrees clockwise. How many pairs of parallel sides does the figure have after the rotation?
Answer:
Step-by-step explanation:
After being rotated by 90 degrees, the figure has 4 pairs of parallel sides.
What is 90° rotation of an object?
The transformation P(x, y) P' can be used to represent a 90° rotation for any point in the plane (x, y) (-y, x). This transition can be produced by applying two reflections.Transformation involves moving a shape from one position to another
Given data ,
A figure with 4 sets of parallel sides is graphed on a grid
The figures with 4 sets parallel sides are : Rhombus, Square , Rectangle
The figure is then rotated 90° clockwise
Now ,
90 degrees clockwise transformation carries the square , rhombus as well as the rectangle onto itself that is after rotation there will be 4 pairs of parallel sides
Hence , after being rotated by 90 degrees, the figure has 4 pairs of parallel sides.

Solve 3kx + 24 = 9 kx for x.
Answer:
Step-by-step explanation:
3kx + 24 = 9kx
First subtract 3kx to both sides.
24 = 9kx - 3kx
24 = 6kx
Divide both sides by 6
24/6 = kx
4 = kx
Divide both sides by k.
4/k = x

A pizza restaurant charges a flat fee for a plain cheese pizza. There is an extra charge for any additional toppings. The cost of a pizza can be determined from the equation c=0.5m+5, where M is the number of additional toppings and see is the cost of the pizza ordered. What are the interpretations of slope and Y intercept in the equation?
Answer:
The y-intercept is the flat fee for the pizza - $5. The slope is the charge for each additional topping - $.50
Step-by-step explanation:
c=.5m+5
y=mx+b - slope intercept formula
In the slope-intercept formula, the 'b' is the y-intercept. We know that would be the flat fee because there is no variable attached to it.
In that formala, m is the slope and is attached to a variable, x. This problem uses the variable m instead of x, but we can see that the slope for .5m would be .5. Thus, that's the charge for the toppings. Hope that helps!

Find x, y, and z
x = 39
x = 29
y = 61
y = 29
z = 61
z = 29
answer:
x = 29
y = 29
z = 61
step-by-step explanation:
all angles in a triangle must equal 180 degrees.
we were already given the angle degree of 61 degrees so we must include that in our formula to determine the degree of y.
the line in the middle already gives us two more angles because they both are 90 degrees for being a perfect quarter turn.
so to figure out y,
we must add 61+90 and then subtract the sum of that from 180.
so, 61+90 = 150 and 180-151 = 29
therefore,
we can conclude that y = 29
now, to determine the degrees of x and z we do the same thing.
we already know one angle equals 90 degrees.
180-90 = 90
that concludes that x and z must have a sum of 90.
if we use our choices,
39+61 = 100 (no)
39+29 = 68 (no)
29+61 = 90 (CORRECT)
29+29 = 28 (no)
therefore, x = 29 and z = 61
so, in total :
x = 29
y = 29
z = 61
