The weight of a soccer ball is normally distributed with a mean of 0.43 kg and a standard deviation of 0.01 kg. Suppose 800 different soccer balls are in a warehouse. About how many soccer balls weigh more than 0.45 kg?
A. 12
B. 20
C. 24
D. 40
Answers
Answer:
Answer is b) 20.
Step-by-step explanation:
Mean is 0.43 kg.
0.43+0.1+0.1= 0.45
0.45 is two standard deviation above.
All that are below mean is 50%,
Two standard deviation above is 95%/2=47.5%
50%+47.5% =97.7% are balls that are less than 0.45 kg.
100%-97.7%=2.5% balls that are more than 0.45 kg
2.3%=0.025
800*0.025 = 20 soccer balls weigh more than 0.45 kg

Happy Paws charges $19.00 plus $4.50 per hour to keep a dog during the day. Woof Watchers charges $10.00 plus $5.75 per hour. Complete the equation and solve it to find for how many hours the total cost of the services is equal. Use the variable h to represent the number of hours.
Answers
Answer:
Hours are equal: 7.2
Cost of service are equal: 51.4
Step-by-step explanation:
Happy Paws:
y = 4.5h + 19
Woof Watchers:
y = 5.75h + 10
To solve for the hours are equal:
y = 4.5h + 19
y = 5.75h + 10 (Multiply by -1)
y = 4.5h + 19
-y = -5.75h - 10
0 = -1.25h + 9
-9 = -1.25h
h = 7.2
To solve for when the services are equal:
y = 4.5h + 19
y = 4.5(7.2) + 19
y = 32.4 + 19
y = 51.4

Alternate interior angles have the same measure. As we know that 'angle 1 ' and 50° are alternate interior angles hence they must be equal. Also we now that sum of all the angles of a triangle is equal to 180°. Hence, m∠2=15°.

a. 6

c. 32
d. 64
Answers
The population of The Colony after 2 hours is d. 64
How to determine the population?The given parameters are:
Initial, a = 1
Rate, b = 2 every 20 minutes
An exponential function is represented as:
y = ab^x
So, we have:
y = 1 * 2^x
y = 2^x
There are six 20 minutes in 2 hours.
This means that:
x = 6
So, we have:
y = 2^6
Evaluate
y = 64
Hence, the population of The Colony after 2 hours is d. 64

Zack has 13 chains at 5 links each. He wants to combine them into a long chain by cutting and welding the fewest number of links. How many different links must be cut a welded.
Answers
Answer:
3
Step-by-step explanation:
There a 5 chains (each with 3 links). We take one chain and cut all three links. Now we are left with only four chains. This requires only 3 joints. Exactly the number of links I have. Therefore, the lowest number of cuts is three.
The number of different links must be cut a welded should be considered as the 3.
Calculation of the number of different links:Since
Zack has 13 chains at 5 links each. He wants to combine them
So here we considered only one chain and then cut off all 3 links
So the remaining should be four chains and it needs only 3 joints.
hence, The number of different links must be cut a welded should be considered as the 3.

A. (F(n))^2
B. 2(f(n))
C. (F(n)-1)^2
D. 2(f(n)-1)
Answers
Answer: (a)
Step-by-step explanation:
Given
The pattern is 2, 4, 16, 256...
From the pattern, we can see that the next term is square of the previous i.e.
[tex]\Rightarrow 4=2^2\\\Rightarrow 16=4^2\\\Rightarrow 256=16^2[/tex][tex]\Rightarrow 4=2^2\\\Rightarrow 16=4^2\\\Rightarrow 256=16^2[/tex]
So, for the [tex]n^{th}[/tex] term, the function is [tex]f(n)[/tex]
For the next term, it is [tex]f(n+1)[/tex]
So,
[tex]\Rightarrow f(n+1)=[f(n)]^2[/tex]
hamster runs in its wheel whose r=3. The wheel completes 9.2 rev/sec.what is the linear velocity
Answers
The linear velocity of the hamster is 173.328 m/s.
What is linear velocity?Linear velocity is the rate of change of displacement along a straight line.
To calculate the linear velocity of the hamster, we use the formula below.
Formula:
v = ωr............ Equation 1Where:
v = linear velocityr = radius of the wheelω = Angular velocityFrom the question,
Given:
r = 3 mω = 9.2 rev/sec = (9.2×2π) rad/s = 57.776 rad/sSubstitute these values into equation 1
v = 3(57.776)v = 173.328 m/sHence, The linear velocity of the hamster is 173.328 m/s.

solve the system using substitution x=-4y y=2x+9
Answers
Answer: x=-4
Step-by-step explanation:
Given
x=-4y
y=2x+9
Rephrase equation to find y value in terms of x
y=-x/4
y=2x+9
Use substitution (substitute value of y)
2x+9=-x/4
Multiply -4 on both sides
-4(2x+9)=-4(-x/4)
-8x-36=x
Add 8x on both sides
-8x-36+8x=x+8x
-36=9x
Divide 9 on both sides
-36/9=9x/9
x=-4

This question is incomplete, the complete question is;
Question 1: The National Assessment of Educational Progress (NAEP) is administered annually to 4th, 8th, and 12th graders in the United States. On the math assessment, a score above 275 is considered an indication that a student has the skills to balance a checkbook. In a random sample of 500 young men between the ages of 18 and 20, the mean NAEP math score is 272 with standard deviation of 78.
Do we have evidence to support the claim that young men nationwide have a mean score below 275. The level of significance is 5%
Answer:
p-value ( 0.2 ) > significance level (0.05 )
Fail to reject H₀ at ∝ = 0.05
Therefore, We do not have enough evidence to conclude that the mean score is less than 275 for young men nationwide.
Step-by-step explanation:
Given the data in the question;
Null hypothesis H₀ : μ = 275
Alternative hypothesis Hₐ : μ < 275
mean x' = 272
standard deviation σ = 78
sample size n = 500
Test Statistics
z = (x'-μ) / (σ /√n )
we substitute
z = (272-275) / (78 /√500 )
z = -3 / 3.488266
z = - 0.86
from table;
p-value = 0.19489 ≈ 0.2
Hence; p-value ( 0.2 ) > significance level (0.05 )
Fail to reject H₀ at ∝ = 0.05
Therefore, We do not have enough evidence to conclude that the mean score is less than 275 for young men nationwide.
