Find the value of x so that the function has the given value

k(x) = 6x - 12; k(x) = 18

Answer:

4

Step-by-step explanation:

Answer:

4

Step-by-step explanation:

Ok, so first, you need to get the denominators to be equal so you'd multiply x/5 by 4 to get 4x/20 and -1/4 by 5 to get -5/20

4x/20 - 5/20 = 11/20

add 5/20 to get 16/20

4x/20 = 16/20

multiply both sides by 20 to cancel out fractions

4x = 16

divide by 4

x=4

Hi, I believe the answer here is,

Subtract their absolute values and keep the sign of the integer with the greater absolute value

Step-by-step explanation:

No. of coins in pounds → 1/3 x 498 = 166

No. of coins in 50p → 124

No. of coins in 20p → 498 - 166 - 124 = 208

Total Value: 166pounds + 124 (50p) + 208 (20p)

unfortunately, I do not know the exact currencies of pounds and "p" so I'm sorry I'm afraid but I can't calculate the total value

Answer:

30

Step-by-step explanation:

4t^2-6 when t is 3

Since we know t=3, we can substitute that in

4(3^2) - 6

Simplify.

3^2 = 9

= 4(9) - 6

= 36 - 6

= 30

Answer:

The probability that the sample proportion is within 0.03 of the population proportion is 0.468.

Step-by-step explanation:

The complete question is:

A company makes auto batteries. They claim that 84% of their LL70 batteries are good for 70 months or longer. Assume that this claim is true. Let p^ be the proportion in a random sample of 60 such batteries that are good for 70 months or more.  What is the probability that this sample proportion is within 0.03 of the population proportion? Round your answer to two decimal places.

Solution:

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=0.84\\n=60[/tex]

As the sample size is large, i.e. n = 60 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion of LL70 batteries that are good for 70 months or longer.

Compute the probability that the sample proportion is within 0.03 of the population proportion as follows:

[tex]P(-0.03<\hat p-p<0.03)=P(\frac{-0.03}{\sqrt{\frac{0.84(1-0.84)}{60}}}<\frac{\hat p-p}{\sigma_{\hat p}}<\frac{-0.03}{\sqrt{\frac{0.84(1-0.84)}{60}}})\\\\=P(-0.63<Z<0.63)\\\\=P(Z<0.63)-P(Z<-0.63)\\\\=0.73565-0.26763\\\\=0.46802\\\\\approx 0.468[/tex]

Thus, the probability that the sample proportion is within 0.03 of the population proportion is 0.468.

Answer: its 20.5 i think i hope its right

Step-by-step explanation:

Answer: The equation is: 11+5.75h=19+4.5h The total cost of the services will be equal at 6.4 hours

Step-by-step explanation:
11 + 5.75h = 19 + 4.5h

-11 from both sides

5.75h = 8 + 4.5h

-4.5h from both sides

1.25h = 8

8 / 1.25 = 6.4,

Therefore, h=6.4

$14.4

Step-by-step explanation:

First set a porpotion of 20/100 = x/18

Then do 20x18=360

360 Divided by 100=3.6

So 18-3.6=14.4

Answer:

0.25239

Step-by-step explanation:

We start by calculating the z-score

Mathematically;

z-score = (x-mean)/SD

Z-score = (19.5-20.5)/1.5

z-score = -0.667

The probability we want to calculate is;

P( x < -0.667)

we can use the standard normal distribution table to get this

That would be;

0.25239

P( x < -0.667) = 0.25239

Answer:

-(8-1+5), -8+1-5,

Only two of the list are a match for the answer of -8- (-1) – 5.

-8- (-1) – 5 = -12

-(8-1+5 = -12

-8+1-5 = -12

Have a beautiful day!

The expression into an equivalent form -8- (-1) – 5 would be;  -(8-1+5), -8+1-5,

Since expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it more complex or simple.

We need to find the expression into an equivalent form -8- (-1) – 5

This expression could also be given by;

-8- (-1) – 5

Now, we know that the list is a match for the answer of -8- (-1) – 5.

-8- (-1) – 5 = -12

-(8-1+5) = -12

-8+1-5 = -12

Hence, -(8-1+5), -8+1-5, are the correct expression.

Answer:

I think it would be D. I'm not sure but I think so. I thought C at first but (go to explanation)

Step-by-step explanation:

if image 1 is the original, then image 2 would be it reflected over the y axis

C says over the line y=0 which would be a horizontal line. x=0 would be a vertical line aka the y axis. I believe its D.
