Please anyone help me
Answer:
-52
Step-by-step explanation:
plug 2 into u(x) which is equal to
2(5) + 1= 5
plug 5 into w(x) which is equal to
-2(5^2) - 2
-2(25) - 2
-50 - 2 = -52
A local car dealer has 150 vehicles on the lot. 55% of the vehicles are trucks, 15% are minivans, and the rest of the cars are sedans. How many of the cars are sedans?
Answer:

Step-by-step explanation:
55% + 15% = 70% which means 30% are Sedans.
30%= .3
.3 x 150 cars = 45 Cars

Last month, Sheldon earned $12.80 in interest on a $320 deposit into his bank account. If the interest earned is directly proportional to the amount deposited, how much interest can Sheldon expect next month if he deposits $830?
Answer:
[tex]x=\$ 32.20[/tex]
Step-by-step explanation:
[tex]\frac{12.80}{320}=\frac{x}{830} \therefore 320x=830\times12.80[/tex]
[tex]x=\$ 32.20[/tex]
Answer:
the answer is $487.20 if he expects to deposits $830

What is the quotient of 6/7 and 3/14
Answer:
6/7 divided by 3/14=4
Step-by-step explanation:
Hope this helps!
Answer: 4
Step-by-step explanation: To divide fractions, you have to switch the operation to multiplication, and multiply the first fraction by the reciprocal of the second fraction. So 6/7 times 14/3. Cross cancel out, so 14 and 7. 7 cancels out to be 1, 14 cancels out to be two. 6 and 3, are the same thing. So in the end you have 2/1 times 2/1 which is 4.
Ramona completed all 30 questions on the test. If 5/6 of the questions were correct, how many questions
did Ramona answer incorrectly?
Help taking a test.!
Answer:
If Romona Complete all 30(Don't forget to group all 30) 5/6 were correct! then you will need to subtract 30-5/6= so that would be 29 1/6 Then if you need to find the amount that would be right take the Whole number! so take 30/50 and divide and you should get your answer!

Suppose a large shipment of laser printers contained 22% defectives. If a sample of size 276 is selected, what is the probability that the sample proportion will differ from the population proportion by less than 6%
Answer:
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
[tex]\mu_{\hat p}=p\\\\[/tex]
The standard deviation of this sampling distribution of sample proportion is:
[tex]\sigma_{\hat p}=\sqrt{\frac{p(1-p)}{n}}[/tex]
The information provided is:
[tex]p=0.22\\n=276[/tex]
As the sample size is large, i.e. n = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of [tex]P(\hat p-p<0.06)[/tex] as follows:
[tex]P(\hat p-p<0.06)=P(\frac{\hat p-p}{\sigma_{\hat p}}<\frac{0.06}{\sqrt{\frac{0.22(1-0.22)}{276}}})\\\\=P(Z<2.41)\\\\=0.99202\\\\\approx 0.992[/tex]
Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
It said that it was wrong.
