Bold (a )What percent of sample proportions results in a 90% confidence interval that includes the population proportion? Bold (b )What percent of sample proportions results in a 90% confidence interval that does not include the population proportion?
Complete Question
The horizontal axis in the sampling distribution of [tex]\^p[/tex] represents all possible sample proportions from a simple random sample of size n.
a. What percent of sample proportions results in a 90% confidence interval that includes the population proportion?
b. What percent of sample proportions results in a 90% confidence interval that does not include the population proportion?
Answer:
a
90% of all possible sample proportions
b
(100% - 90% = 10% ) of all possible sample proportions
Step-by-step explanation:
Generally given from the question that the horizontal axis of a represent all possible sample proportion then then the percent of the sample proportion that result in 90% interval that includes the population proportion is 90% of all possible sample proportions
Generally given from the question that the horizontal axis of a represent all possible sample proportion then the percent of the sample proportion that result in 90% interval that does not include the population proportion is (100% - 90% = 10% ) of all possible sample proportions
It’s the red one but tell me why plz now hurry 4 min left
Answer:
you can plug in x to find y then use them as coordinates to find your answer.
Step-by-step explanation:
ex:
y=((1)-4)^2-3
y= (-3)^2-3
y=9-3
y=6
so then check to see if (1,6) is a point in that line.

Answer: -53, 53
Step-by-step explanation:
It’s asking for the slope first, so let’s find it:
First, let’s determine our coordinates.
We have (1, 930) and (6, 655).
The slope equation is [tex]\frac{y_1 - y_2}{x_1 - x_2}[/tex], so let our (1, 930) be our x_1 and y_1, and (6, 655) be our x_2 and y_2.
So, we have,
= [tex]\frac{655-930}{6-1}[/tex]
This simplifies to
= [tex]\frac{-265}{5}[/tex]
which is -53.
Therefore, the slope is -53, so the balance decrease by $53 each month.

Answer:
It is 4 4/15
Step-by-step explanation:
We convert 2/3 and 3/5 to fifteenths because we cant add numbers with different denominators.
2/3 = 10/15 | 3/5 = 9/15
10/15 + 9/15 = 19/15 = 1 4/15. Then, we add the 3.
3 + 1 4/15 = 4 4/15.

Part A: 5/26
Part B: 5/26+ 1/2 which is 18/26 or 9/13
Part C: 5/26 +21/25. 'without replacing' means there is one less option in the bag. So denominator becomes 26-1=25. Numerator is 21 because there are a total of 21 consonants in the alphabet. Since we removed a vowel and not a consonant, it will remain 21.

a) Work out the rate of change during the first 4 seconds.
b) Work out the rate of change between 8 seconds and 12 seconds.
Answer:
a. 37.5
b. 25
Step-by-step explanation:
a. Rate of change the first 4 seconds can be calculated using the points (0, 0) and (4, 150):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{150 - 0}{4 - 0} = \frac{150}{4} = 37.5 [/tex]
b. Rate of change between 8 seconds and 12 seconds using the points (8, 150) and (12, 250):
Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{250 - 150}{12 - 8} = \frac{100}{4} = 25 [/tex]
Write an equivalent expression
-3 + 2/3y - 4 - 1/3y
Answer:
join the y-related together and the others together
ie -7+1/3y
thats the shortest form one can drill down to, so that should be the answer
Step-by-step explanation:
To write an equivalent expression, we need to simplify the given expression by combining like terms. Like terms are terms that have the same variable and exponent. We can use the distributive property to remove parentheses or other grouping signs to then combine like terms.
The given expression is -3 + 2/3y - 4 - 1/3y. We can see that there are no parentheses or grouping signs, so we can skip that step. We can also see that there are two like terms: 2/3y and -1/3y. We can combine them by adding their coefficients: 2/3 + (-1/3) = 1/3. So, we get:
-3 + 2/3y - 4 - 1/3y = -3 - 4 + (2/3 - 1/3)y = -7 + (1/3)y
This is the simplified expression that is equivalent to the given expression.

A fire jet flies at an altitude of 25,000 feet and then dives to a depth of 600 feet below sea level. What is the difference in its elevation?
Answer:
25,600 feet in difference
Step-by-step explanation:
If the jet is 25,000 feet above sea level then dives 600feet below sea level that will be 25,600 feet in difference.
25,000 - - 600
25,000 + 600

Find the surface area of the square pyramid
Answer:
The surface area of the square pyramid is 40 units².
Step-by-step explanation:
As we know that the total surface area of a square pyramid can be obtained by identifying the length 'b' of its base and its slant height 's' by using the formula:
[tex]A=2bs+b^2[/tex]
From the figure, it is clear that
length of its base = 'b' = 4slant height = 's' = 3substituting the values in the formula
[tex]A=2bs+b^2[/tex]
[tex]A=2\left(4\right)\left(3\right)+\left(4\right)^2[/tex]
[tex]=2\left(4\right)\left(3\right)+16[/tex]
[tex]=40[/tex]
Therefore, the surface area of the square pyramid is 40 units².
What is the value of x?
A.22
B.38
C.42
D.5
Answer: B) 38
Step-by-step explanation:
1) [tex]x+(x+6)+(3x-16)=180[/tex] (sum of angles in triangle)
2) [tex]5x-10=180[/tex] (Algebra)
3) [tex]5x=190[/tex]
4) x= 38 degrees
Answer: x = 38
Step-by-step explanation:
1) Add 3x - 16 and x + 6 and x together. You get 5x - 10.
2) All sides of a triangle equals 180 degrees, so that means 5x - 10 = 180.
3) Add 10 to both sides, 5x = 190.
4) 190/5 = 38
5) 38 is your answer.

Solve the inequality 5x – 7 > 4x + 8
Answer:
x > 15
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define inequality
5x - 7 > 4x + 8
Step 2: Solve for x
Subtract 4x on both sides: x - 7 > 8Add 7 on both sides: x > 15Here we see that any value x that is greater than 15 would work as a solution to this inequality.
Can someone please help me, I really need it
Answer:
∠EGA = 123°
∠EHD = 57°
Step-by-step explanation:
Determine the measure of ∠EGA:
Since ∠EGB and ∠EGA make up the angle of a straight line (180°):
∠EGB+∠EGA = 180
57+∠EGA = 180 (given that ∠EGB = 57°)
∠EGA = 123°
Determine the measure of ∠EHD:
∠EHD = ∠EGB (corresponding angles of parallel lines are equal)
∠EHD = 57° (given that ∠EGB = 57°)

19.97
The simplified value of the expression 18.1 - 1.1(7.4 - 9.6 + 0.5) is 36.8.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, An expression 18.1 - 1.1(7.4 - 9.6 + 0.5).
let us multiply each term of the expression to remove the decimal.
∴ 181 - 11(74 - 96 + 5).
= 181 - 11(-17).
= 181 + 187.
= 368 but the actual answer is 36.8 as we have to divide by 10.
