Lana correctly answered 48 of 60 questions on a math exam. What percent of questions did she answer correctly?
Answer:
I think it roughly 66.67%
Step-by-step explanation:
sorry if I'm no help
The percent of questions she answered correctly is 80%.
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Given;
Lana correctly answered 48 of 60 questions on a math exam
Now,
=48*100/60
=480/60
=80
Therefore, the percentage will be 80%.

The head of maintenance at XYZ Rent-A-Car believes that the mean number of miles between services is 3408 miles, with a variance of 249,001. If he is correct, what is the probability that the mean of a sample of 36 cars would be less than 3245 miles
Answer:
The probability that the mean of a sample of 36 cars would be less than 3245 miles
P(X⁻≤3245) = 0.975
Step-by-step explanation:
Step(i):-
The mean number of miles between services
μ= 3408 miles
The Variance of miles between services
σ² = 249,001
σ = √249,001 = 499
Let 'X' be a random variable in a normal distribution
Given sample size 'n' =36
Step(ii):-
[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
Z = -163/83.16 = 1.96
The probability that the mean of a sample of 36 cars would be less than 3245 miles
P(X⁻≤3245) = P(Z≤1.96)
= 0.5 + A(1.96)
= 0.5 + 0.4750
= 0.975
Final answer:-
The probability that the mean of a sample of 36 cars would be less than 3245 miles
P(X⁻≤3245) =0.975

HELP!!!! Read the following story carefully, and then complete the activities that follow.
"Good-bye, Mom," Tino cried as he rushed out the door. Tino had his new fishing pole with him and was anxious to try it out.
Tino Kanaha (kan' ah hah) was a Hawaiian boy. He had just turned twelve the day before and had received the fishing pole as a gift from his father.
Tino's house was about a half mile from the cliff overlooking the leeward side of Maui. Many times Tino had climbed down to the rocks below and looked for seashells while his father fished for aku.
"Now it's my turn," thought Tino as he scurried out onto one of the rocks, "and I get to do it all by myself!"
"Aku, here I come!" yelled Tino excitedly as he cast his bait into the surf.
An hour later, Tino heard someone call his name. He looked up and saw his good friend, Kona. "Have you caught anything?" Kona yelled.
"Oh, hi, Kona," Tino said disappointedly. "Wait for me, and I'll be right up."
As Tino reeled in his line, he noticed the waves were much bigger than they had been before. "The wind is stronger, too, " thought Tino as he glanced at the darkening sky.
"We'd better hurry home," Tino said to Kona as he reached the top of the hill. The two boys ran as quickly as they could. They even took the short cut through the sugar cane field to save time.
Kona raced into his yard and, without stopping, he yelled, "Good-bye, Tino! I'll see you tomorrow!"
The first big drops of rain began to fall as Tino reached the front door of his house.
"Oh, I'm glad you're home!" Mrs. Kanaha said. "It is beginning to rain very hard!"
"The storm must be the reason the fish weren't biting," Tino said as he put his fishing pole into the rack on the porch, "but I'll try again tomorrow."
Give two details that are clues that Tino did not catch any fish.

2 points
A) I and II only
B) I and III only
C) II and III only
D) I, II, and III
Answer:
The answer is D.
Step-by-step explanation:
1. 10(k+4) → 10•k + 4•10 → 10k+40
2. is how it is
3. 5(2k+8) → 5•2k + 5•8 → 10k+40

Step-by-step explanation:
You multiply the two numbers together:
Top left, purple tile: 3x(x) = 3x^2
Top right, pink tile: 4(x) = 4x
Bottom left, yellow tile: 3x(2) = 6x
Bottom right, blue tile: 4(2) = 8
Basically u multiply the variable above it and the variable at its left
The color reference provided by the automotive manufacture is 44.21%. Does this known value match the measured value at the 95% confidence level
Answer:
This known value does not match the measured value at the 95% confidence level.
The 95% confidence interval for value is calculated as 42.92 to 43.78%,
Step-by-step explanation:
The complete question is:
Police have a hit-and-run case and need to identify the brand of red auto paint. The percentage of iron oxide, which gives paint its red color, was determined to be 43.35 ± 0.33% by one method of analysis using five measurements. The color reference provide by the automotive manufacture is 44.21%. What can you conclude about whether the sample matches the reference at a 95% confidence level?
Student's t test is used to compare the two values .
Here n=5
Degrees of freedom =ν= n-1= 5-1=4
The value from t- table for 4 d.f at 95 % confidence interval is 2.776
The test statistic is
x`± t ∝/2(v). S/√n
43.35 ± (2.776)(0.33)/√5
= 43.35 ± 0.43
= 43.78, 42.92
Here the 95% confidence interval for μ calculated is 42.92 to 43.78%, where as color reference provided by the automotive manufacture is 44.21%.
This known value does not match the measured value at the 95% confidence level.
