Answer:
The mean is [tex]\mu_{\^ p } = p = 0.35[/tex]
The standard error is [tex]SE = 0.06745[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 50
The population proportion is [tex]p = 0.35[/tex]
Generally given that the sample size is large enough , then the mean of the distribution is mathematically represented as
[tex]\mu_{\^ p } = p = 0.35[/tex]
Generally the standard error of the distribution is mathematically represented as
[tex]SE = \sqrt{\frac{p (1- p )}{n} }[/tex]
=> [tex]SE = \sqrt{\frac{0.35 (1- 0.35 )}{50} }[/tex]
=> [tex]SE = 0.06745[/tex]

Answer:
x = 47.5
Step-by-step explanation:
The vertical angle theorem states that if two angles are vertical, they are congruent, so the two angles you gave are congruent.

A student uses the method of successive approximations to estimate a positive solution of f(x) = g(x), where f(x) = x2 + 10 and g(x) = 2x + 17. The table shows her results for different input values of x. x f(x) g(x) 0 10 17 1 11 19 2 14 21 3 19 23 4 26 25 3.5 22.25 24 Using this method, the next number selected should be between and .
Answer:
The next number selected should be between 2 and 3 .
Step-by-step explanation:
x. x f(x) g(x)

1 11 19
2 14 21
3 19 23
4 26 25
3.5 22.25 24
2.5 16.25 22
1.5 12.25 20
0.5 10.25 18
We see the pattern that it is increasing with only a unit. The last given data is mid of the last two values that is 3 and 4.
So the next value would be the mid of the next last two values that is 2 and 3 and will be 2.5
Now it is moving in the reverse direction in the same pattern with a difference of a unit.

Sh’qira reads an article about a family of wildcats. One of them had a mutation for tooth sharpness. Which of these statements about the wildcat with the mutation is true?
a
There must have been a change in the wildcat’s genes.
b
The wildcat must have sharper teeth.
c
There will be no change to the wildcat’s teeth.
d
The wildcat must have less sharp teeth.
Answer:
There must have been a change in the wildcat’s genes.
Step-by-step explanation:
The question is an illustration of correlation and causation.
The true statement about the wildcat with the mutation is: (a) there must have been a change in the wildcat’s genes.
From the question, we understand that
Of all the wildcats, only one of them has a mutation for tooth sharpness
This means that:
The wildcat has a different trait from other wildcats.
Of all the given options, the true option is (a)

I need help on this please? Thanks
Answer:
6x^2 -9
Step-by-step explanation:
1. From the table, you know that when x = 0, y = -9, this means that the initial value is -9. This means that the last option is not correct
*** y values -> output
2. Plug in a x - value from the table to figure out the right rule:
x = 2
First option: 6x - 9 -> 6*2 - 9 = 12-9 = 7
in the table, the output for x =2 is 15 so the first option is not correct
Second option: 6x^2 - 9 -> 6*(2^2) - 9 = 6*4 - 9 = 24 - 9 = 15
in the table, the output for x =2 is 15 so the second option is correct

A cone has a volume of 135 pi units^3 What is the height of the cone if the diameter of the cone is 18 units long?
Considering the volume of a cone, the height if the cone is 5 units.
A cone is a three-dimensional figure with a circular base, where a curved surface connects the base and the vertex.
The cone is a figure that is generated by rotating a right triangle around one of its legs.
Volume is the place that a body occupies in space.
In the case of the cone, the volume is calculated knowing the height (h) and the radius (r). Its volume is defined as one third of the area of the base B times the height h. This is:
V=[tex]\frac{1}{3}[/tex] ×B ×h
Being B=π× r²
V=[tex]\frac{1}{3}[/tex] ×π× r² ×h
In this case, you know:
V= 135π units³r=diameter÷2= 18 units÷2= 9 unitsh= ?Replacing:
135π units³= [tex]\frac{1}{3}[/tex]×π× (9 units)² ×h
Solving:
135π units³= [tex]\frac{1}{3}[/tex]×π× 81 units² ×h
135π units³÷ ([tex]\frac{1}{3}[/tex]×π× 81 units²)= h
5 units= h
Finally, the height if the cone is 5 units.

Answer:
3x²+7x-6
Step-by-step explanation:
Original Equation;
(x+3)(3x-2)
Multiply the first term by the second term.
x(3x-2)+3(3x-2)
Multiply x by 3x and x by -2
3x²-2x+3(3x-2)
And then multiply 3 by 3x and 3 by -2
