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]

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

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

major in biology,
5. Both Noma and Reynoso considered Penn Valley as their second
choice.
6. Akinte and Oslowski both were summer counselors at Sierra Tech,
even though neither one will go there during the regular year.
Answer and explanation:
Akinye Reynoso

Norma van hee
Jenny olowski
Akinte is not going to the University of Memphis nor university of Sierra tech nor university of Penn valley but goes to St Mary just like Reynoso(his surname)
Chuck is not going to St Mary nor Sierra tech nor Penn valley but goes to Memphis just like pennigan
Norman does not go to Memphis nor Penn valley nor St Mary but goes to Sierra tech just like van hee
Jenny does not go to Sierra tech nor St Mary nor Memphis but goes for Penn valley just like olowski
Akinte Reynoso is the full name of Akinte and he is going to the St. Mary collage, Chuck Peningan is the full name of the chuck and he is going to the Memphis collage, Norma van hee is the full name of the Norma and he is going to the Sierra tech collage and Jenny olowski is the full name of the Jenny and heis going to the Pann vally collage.
Given-
Four students going to college next year are Akinte, Chuck, Jenny, Norma.
According to clues given in the question, Akinte is not going to the University of Memphis or university of Penn valley. From the clue 6 he is also not going to the university of Sierra tech . Now only Reynoso is going to the St. Mary which is the surname of the Akinte.
Chuck is not going to St Mary, Sierra tech or Penn valley. He Memphis as pennigan which is his surname.
Norman does not go to Memphis, Penn valley or St Mary. He goes to Sierra tech as van hee which is his surname
From the clues Jenny does not go to Sierra tech, St Mary or Memphis. He goes for Penn valley as olowski, which is his surname.
Akinte Reynoso is the full name of Akinte and he is going to the St. Mary collage, Chuck Peningan is the full name of the chuck and he is going to the Memphis collage, Norma van hee is the full name of the Norma and he is going to the Sierra tech collage and Jenny olowski is the full name of the Jenny and heis going to the Pann vally collage.

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!

Step-by-step explanation:
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

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.
