A survey asks a random sample of 2500 adults in Ohio if they support an increase in the state sales tax from 5.25% to 5.50%, with the additional revenue going to education. Let X denote the number in the sample that say they support the increase. Suppose that 30% of all adults in Ohio support the increase.
9. The standard deviation of X is
a. 22.91.
b. 27.39.
c. 5255.
d. 750.
10. The probability that X is at least 800 is
a. less than 0.0001.
b. about 0.015.
c. 0.025.
d. 0.05.
Answer:
Step-by-step explanation:
a) Total number of people surveyed, n = 2500
Let X denote the number in the sample that say they support the increase. If 30% of all adults in Ohio support the increase, it means that the percentage of all adults in Ohio that did not support the increase is
100 - 30 = 70%
This is a binomial probability because there are only two possible outcomes. Therefore,
Probability of success, p = 30/100 = 0.3
Probability of failure, q = 1 - p = 1 - 0.3
q = 0.7
Standard deviation = √npq
Standard deviation = √(2500 × 0.3 × 0.7) = 22.91
b) The probability that x is at least 800 is expressed as
P(x ≥ 800)
We would determine the probability by using the binomial probability calculator. Therefore,
P(x ≥ 800) = 0.01577
b. about 0.015.
Which compound inequality is equivalent to the absolute value inequality |b| greater than 6? –6 > b and b > 6 b > –6 or b < 6 –6 < b and b > 6 b < –6 or b > 6
Answer:
The correct inequality is: b< -6 or b > 6
Step-by-step explanation:
The absolute value operator always results in a positive number, in such a way that if b > 0, then |b| = b, while if b < 0, then |b| = -b. With this in mind, let's look at the inequality given:
|b| > 6
This will be true for values of b that are greater than 6 and values of b that are less than -6, due to the absolute value operator. Therefore the compound inequality that represents this situation is:
b< -6 or b > 6
Answer:
I think it is D (and)
Step-by-step explanation:
"Or" means that the b value can be less than -6 or greater than 6
so it could satisfy either one
so if you plug in a value that satifies one of the inequalities (ex: -7)
|-7|>6 and it works!

What is the y-intercept of this function?
f(x) = 2(x - 7)2 - 32
(0,-32)
(0,66)
(0,-7)
(0,17)
Answer:
(0, 66 )
Step-by-step explanation:
To find the y- intercept, let x = 0 and solve for y
f(0) = 2(0 - 7)² - 32
= 2(- 7)² - 32
= 2(49) - 32
= 98 - 32
= 66
The coordinates of the y- intercept are (0, 66 )

Derek uses a 52 inch flat steel bar that weighs 10.4 lbs to make a rack in the garage. Find the weight of a 67-inch steel bar?
Answer:
13.4lbs
Step-by-step explanation:
10.2/52 = 0.2lbs per inch
0.2(67) = 13.4lbs
Using unitary method, the weight of a 67 inch steel bar is 13.4 lbs.
What is unitary method?The formula of the unitary method is to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.
Weight of 52 inch flat steel bar = 10.4 lbs.
Weight of 1 inch flat steel bar = 10.4/52 = 0.2 lbs.
Weight of 67 inch flat steel bar = 0.2 * 67 = 13.4 lbs.

Answer:
52
Step-by-step explanation:
This is an isosceles triangle, so the base angles will be the same. Then you know that all of your angles will add up to 180.
Your equation can be:
2(2x+2) + (3x + 1) = 180
x = 25
S = 2(25) + 2
S = 52 degrees
Answer:
52
Step-by-step explanation:
Because SR = TR, ∡S =∡T= 2x+2
For any triangle sum of all angles = 180°.
2x+2 +2x+2+3x+1= 180
7x + 5 =180
x = 25°
∡S =2x+2=2*25+2 = 52°

6 cube/to the 3rd units
Step-by-step explanation:
um idk if this is what you want but yeah
if you spilt it into a 2x2x1 and a 1x2x1 you can count that there are 6 cube units
Answer:6 cubes
Step-by-step explanation:
There are 2 ways that I think you could solve this.
1. First, you could make those 2 missing cubes actual cubes, so then you could find the volume of the cube by doing 2x2x2(length x width x height) and you would get 8 cubes. After that, you would take away the two missing cubes, and you would get 6 cubes.
2. You could also just count the cubes. I counted the two inner cubes and then counted the 4 outer cubes, and got 6 cubes.
Hope this helps!

Answer:
3.625
Step-by-step explanation:
Line segment IK = 35.
This is a parallelogram, in which:
LJ is a line bisector of IK; line Imidpoint = line segment kmidpoint.
IK = (4x + 3) + (4x + 3)
35 = (4x + 3) + (4x + 3)
Simplify. Combine like terms:
35 = 8x + 6
Simplify. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS =
Parenthesis
Exponents & Roots
Multiplication
Division
Addition
Subtraction.
First, subtract 6 from both sides:
35 (-6) = 8x + 6 (-6)
35 - 6 = 8x
29 = 8x
Divide 8 from both sides:
(29)/8 = (8x)/8
x = 29/8
x = 3.625
3.625 is your answer.

Answer:
X= 8
The reason why X equals 8 is because the gave you the measurement of points I and K. They have created an expression to find points I and K and all they ask you to do is find the value of x.
To find the value of x, think about the measurement of points I and K. The measurements of point I and K equals 35. So we have to substitute a number for x that would make the expression equal 35. This is how I did it, so I thought 4 times what would get me close to 35. Then 4*8 came to my head and that automatically equals 32 and then when you add the three you get 35!

We know that a^b * a^c = a^(b+c)
4^5 * 4^-7 = 4^(5-7) = 4^2
4^2 ÷ 4^-2
