Answer:
reject H0 ; conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters
Step-by-step explanation:
x = 115
n = 200
Phat = x / n = 115 / 200 = 0.575
H0 : P0 ≥ 0.65
H1 : P0 < 0.65
TEST STATISTIC :
Phat - P0 ÷ sqrt[(P0(1-P0))/n]
0.575 - 0.65 ÷ sqrt[(0.65(0.35))/200]
-0.075 ÷ 0.0337268
Test statistic -2.237
Pvalue :
P(Z < - 2.237) = 0.012643
α = 0.05
Pvalue < α
0.012643 < 0.05 ; We reject H0
We can conclude that there is significant evidence to conclude that candidate A is supported by less than 65% voters

Gerald has a bag of 10 colored balls: 3 green, 3 red, and the rest yellow. He randomly draws two balls, one at a time without replacement. Find the probability of drawing at least one yellow ball.
Answer:
2/3
Step-by-step explanation:
Probability is the ratio of the number of possible outcome to the number of total outcome.
Given that there are 10 balls of which 3 green, 3 red, and the rest yellow
Number of yellow balls = 10 - 3 - 3 = 4
Probability of picking a;
Green ball = 3/10
Red ball = 3/10
Yellow ball = 4/10
If two balls are picked without replacement, the probability that one is at least yellow will be
YR RY YG GY YY
= 4/10*3/9 + 3/10*4/9 + 4/10*3/9 + 3/10*4/9 + 4/10*3/9
=12/90 *5
= 2/3
How do you write the equation for this word problem: DeShawn spent $650 on pairs of pants. Dress pants cost $100 and jeans cost $70. If he bought a total of 8, then how many of each kind did he buy? And can you please show this step by step. Thank you

Use a factor tree or similar method to write 4400 as a product of
prime factors. Display your factor tree in your answer. If you
choose to use an alternative method, clearly show your working:
just writing down the answer is not sufficient.
Answer:
4,400 = 44 * 100
44 = 2 * 2 * 11
100 = 2 * 2 * 5 * 5
prime factors = 2 * 2 * 2 *2 * 5 * 5 * 11

Find the value of x if 2x = 20 .
Answer:
x = 10
Step-by-step explanation:
Divide both sides by 2.
(2x) / 2 = 20 / 2
x = 10
Answer:
The answer is going to be 10.
Step-by-step explanation:
1) Diving both sides by 2.
[tex]x = \frac{20}{2} [/tex]
2) Simplify 20/2 to 10 because 20 ÷ 2 is 10.
[tex]x = 10[/tex]
Therefor, the answer for x is x = 10.

Donna borrowed $10, 500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether?
Donna borrowed $10,500 at a simple interest rate of 4% for 3 years to buy her new car. How much interest would Donna pay and how much is the car altogether ?
Answer:-Given:-[tex] \bullet [/tex] Principal (P) = $10,500
[tex] \bullet [/tex] Rate of interest (r) = 4%
[tex] \bullet [/tex] Time (t) = 3 years
To Find:-Interest of Donna and amount of car altogether.
Solution:-We know,
[tex] { \boxed{\rm \red {I \: = \frac{Prt}{100}}}} [/tex]
[tex] \therefore [/tex] I = [tex] \frac{10,500 \: × \: 4 \: × \: 3}{100} [/tex]
I = [tex] \frac{126,000}{100} [/tex]
I = $1260
Now,
Amount of the car = $ (10,500 + 1260)
= $ 11,760
$1260 interest would Donna pay and $11,760 is the car altogether. [Answer]Step-by-step explanation:
We know that Interest = Principal×Rate×Time/100
So,
10,500×4×3/100
= 10,500×3/25 (by cancelling 100 by 4)
=31500/25
= 1260
Therefore,
$1260 Answer

A bakery sells chocolate cupcakes and mocha cupcakes. One day it sold 153 chocolate
and 187 mocha. What percent of the cupcakes sold that day were chocolate?
Answer:
45% of the cupcakes baked on that day were chocolate flavored.
Step-by-step explanation:
Hey there!
We're given that the bakery sold 153 chocolate cupcakes and 187 mocha cupcakes.
Let's find the total number of cupcakes baked in a day.
[tex]153 + 187 = 340[/tex]Now, we need to find the ratios of the cupcakes. Of the 340 cupcakes baked, 153 were chocolate flavored. Therefore, we can create a ratio between the two values and find the percentage.
Step 1: Define Values
153 chocolate cupcakes baked340 cupcakes in totalStep 2: Create Ratio and Simplify
[tex]\displaystyle \frac{\text{153 chocolate cupcakes}}{\text{340 total cupcakes}} = \frac{153}{340} = 0.45[/tex]
Step 3: Convert from Decimal Form to Percentage Form
[tex]0.45 \times 100\% = 45\%[/tex]
Therefore, we have determined that 45% of the cupcakes baked on that day were chocolate flavored.

What is the length of the unknown leg in the right triangle?
Answer:
15m
Step-by-step explanation:
a^2 + b^2 = c^2
a=?
b = 20m
c = 25m
a^2 + (20m)^2 = (25m)^2
a^2 + 400m^2 = 625m^2
a^2 = 625m^2 - 400m^2 = 225m^2
a = 15m

which polynomial is a perfect square trinomial?
A. 49x^2 - 28x + 16
B. 4a^2 - 20a + 25
C. 25b^2 - 20b - 16
D. 16x^2 - 24x - 9
Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative
