Answer: b. Yes
Step-by-step explanation: Confidence Interval for a population proportion is calculated as:
p ± [tex]z\sqrt{\frac{p(1-p)}{n} }[/tex]
where
p is the sample proportion
n is sample size
z is z-score, in this case, as it is 95%, z-score=1.96
Calculating confidence interval:
[tex]p=\frac{152}{468}[/tex]
p = 0.3248
0.3248 ± [tex]1.96\sqrt{\frac{0.3248(0.6752)}{468} }[/tex]
0.3248 ± [tex]1.96\sqrt{0.000468}[/tex]
0.3248 ± 0.0425
Interval: 0.2823 < μ < 0.3673
The interval means we are 95% sure the true mean is between 0.2823 and 0.3673. As the campaign claims a proportion of no more than 0.32 of the voters wants to see Mayor Waffleskate defeated and the number is in the confidence interval, the claim is supported.

8g - 7 = 5g + 6. What is g?
what is the y intercept of f(x)=(1/2)x?
Answer: C (0,1)
Step-by-step explanation:
The y intercept of a function is when it's x coordinate is zero, so input 0 into the function and solve for f(x)
f(0) = (1/2)^x
f(0) = (1/2)^0
f(0) = 1 Any number raised to zero is 1 so the y intercept has to be 1.

Step-by-step explanation:
Use the distributive property-
To “distribute” means to divide something or give a share or part of something. According to the distributive property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Solve for X geometry
Answers
1. x=7
2. x=6
3. x=9
4. x=8
Explanations
1. This is an isosceles triangle because two angles are congruent. This also means the two sides are the same. This means 7 = x.
2. This is an equilateral triangle because all the angles are the same. Therefore, all sides are also the same. So x = 6.
3. This is also an equilateral triangle. We know this because all sides are the same. So from this we know that x-3 = 6. Solve the equation, and you'll find that x = 3.
4. This is also an isosceles triangle, because two of the angles are congruent. This means 2x-9 = 7. Solve this equation; x=8
Answer:
27) x = 7
28) x = 6
29) x = 9
30) x = 7
Step-by-step explanation:
I first added to two angles we already knew. Then, I took that number and subtracted it from the whole number in the algebraic equation. I then divided that number with the value paired with x to get x.

Answer:
Step-by-step explanation:
a. 3-4x=-7-4x
3=-7. no solution
b. 15 - 2x = -7x
15 = -5x
x=-3. one solution
c. 7y-21=6y-21
y=0
1. -3x+4=-3x+7
4=7
2. 10+2x = 5x+2
8=3x
x=3/8
3. x+5=x+5
Answer:
Step-by-step explanation:
a) 3 - 4x = -7 - 4x
- 4x in both terms can be cancelled
3 = -7 ⇒ equation with no solution
b) 15 - 2x = -7x
15 = -5x
-3 = x
x = -3
c) 7 (y - 3) = 6y - 21
7y - 21 = 6y - 21
7y - 6y = -21 + 21
y = 0
1) Equation with no solution:
3x + 5 = 12 + 3x
there is no x that conforms that equation because the result is always 5 = 12, which is inconsistent
2) Equation with one solution
2y -5 = 7 ⇒ y = 12/2 ⇒ y = 6
3) Equation with infinite solutions
x - 10 = x - 3 - 7
Any value of x complies with this equation
Solve a/ -6 + 8 = 12. a=?
Answer: the answer is -24
Step-by-step explanation:
a in (-oo:+oo)
a/(-6)+8 = 12 // - 12
a/(-6)-12+8 = 0
-1/6*a-4 = 0 // + 4
-1/6*a = 4 // : -1/6
a = 4/(-1/6)
a = -24

A cup slides off a 2.5 m high table with a speed of 2.8 m/s to the right. We can ignore air resistance. What was the cup's horizontal displacement during the fall?
Answer:
Horizontal distance = 1.98 m (Approx)
Step-by-step explanation:
Given:
Height = 2.5 m
Speed v = 2.8 m/s
Find:
Horizontal displacement
Computation:
s = ut + (1/2)gt²
2.5 = (1/2)(9.8)t²
t² = 0.5102
t = 0.7079 s
Horizontal distance = (v)(t)
Horizontal distance = (2.8)(0.7079)
Horizontal distance = 1.98 m (Approx)

Circles are taken to circles of the same center and radius.
Line segments are taken to line segments of the same length.
Line segments are taken to line segments of the same length.
Parallel lines are taken to parallel lines.
Answer:
Rotation about the origin only changes the coordinates but angle or segment measures remain same, therefore parallel and perpendicular lines stay as is.
Correct options:
Angles are taken to angles of the same measure.Perpendicular lines are taken to perpendicular lines.Line segments are taken to line segments of the same length.Parallel lines are taken to parallel lines.Write the fraction

Suppose that the batting averages or AVG (hits per at-bat) of all players in the AAA baseball league are normally distributed with a mean of 0.2 and a standard deviation of 0.05. The middle 95% of the player will have a lower bound of:____.a. 0.19.b. 0.03.c. 0.30.d. 0.07.
Answer:
0.1
Step-by-step explanation:
Solving using empirical rule formula
95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .
Hence, the lower bound 95% =
μ - 2σ
Mean = 0.2
Standard deviation of 0.05
= μ - 2σ
= 0.2 - 2(0.05)
= 0.2 - 0.1
= 0.1
The lower bound is 0.1

Q: The circle below has a circumference of 34.56 cm. Find the diameter.
Answer:
11cm = diameter.
c=circumference
d=diameter
π=3.14
r=half of diameter
34.56
C=2πr
d=2r
Solving for d (diameter)
d=C
π=34.56
π≈11.00079cm
rounded = 11cm!
You promised brainlest! Please!!
Step-by-step explanation:
Answer:
11.0008
Step-by-step explanation:
“Since we know circumference and diameter are related by π, we can use π to find diameter if we know circumference”
Equations:
C = πd
C/π = d
Therefore:
34.56 = pi(d)
34.56/3.14159265359 = 11.000789..........
