40÷12= 3.33

so it approximately takes him 3hrs and 18minutes

so 9:15 + 3hrs 18 minutes is 12: 33 pm?

Answer:

1 is correct

Answer:

[tex]x^{2}[/tex] + (y-5)² = 8

Answer:

1 is the radius of the unit circle. I think.

In mathematics, a unit circle is a circle with a radius of one. The unit circle is the circle of radius one centered at the origin (0, 0)

Answer:

g(x) = (x - 10) + 10

Step-by-step explanation:

Hi,

g(x) when moved 10 units right and 10 units up is...

g(x) = (x - 10) + 10

(When moving right, make sure there's a subtraction sign in the parenthesis, when left, remove the subtraction sign, it's weird but that's how it works)

The - 10 is the 10 units right and the + 10 is the 10 units up

Hope this helps :)

Step-by-step explanation:

Answer:

A. 0.33496 = 33.496% probability that one out of the next four cars needs oil.

B. 0.19635 = 19.635% probability that two out of the next eight cars needs oil.

C. 0.01437 = 1.437% probability that 10 out of the next 40 cars needs oil.

Step-by-step explanation:

For each customer, there are only two possible outcomes. Either their car needs to have oil added, or it does not. The probability of a customer having a car needing oil addition is independent of any other customer. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

One out of 8 cars needs to have oil added.

This means that [tex]p = \frac{1}{8} = 0.125[/tex]

A. One out of the next four cars needs oil.

This is [tex]P(X = 1)[/tex] when [tex]n = 4[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 1) = C_{4,1}.(0.125)^{1}.(0.875)^{3} = 0.33496[/tex]

0.33496 = 33.496% probability that one out of the next four cars needs oil.

B. Two out of the next eight cars needs oil.

This is [tex]P(X = 2)[/tex] when [tex]n = 8[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{8,2}.(0.125)^{2}.(0.875)^{6} = 0.19635[/tex]

0.19635 = 19.635% probability that two out of the next eight cars needs oil.

C. 10 out of the next 40 cars needs oil.

This is [tex]P(X = 10)[/tex] when [tex]n = 40[/tex]. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 10) = C_{40,10}.(0.125)^{10}.(0.875)^{30} = 0.01437[/tex]

0.01437 = 1.437% probability that 10 out of the next 40 cars needs oil.

Answer:

Total Sharon spent $660 for the tv

The down payment was $210

The amount that she paid for rent after 6 months is $450

Step-by-step explanation:

To find out how much her down payment was you would need to find out how much 10% of $2,100 is which is $210, so you know her down payment was $210.

Then you would find out the total cost of rent is after 6 months so you would do 6 times $75 which is $450. So if she decides to not buy it then after 6 months she would have spent $450 to rent it.

And total she would have spent $660 which you can find out by doing $450 + $210 = $660.

Answer:

0 and 1.5850

Step-by-step explanation:

Given the expression

2^2x-4^(2^x)+3=0

Let P = 2^x

P² - 4P + 3 = 0

Factorize

P² -3P-P +3 = 0

P(P-3)-1(P-3) = 0

P-1 = 0 and P-3 = 0

P = 1 and 3

If P = 1

2^x = 1

log 2^x = log 1

xlog 2  =0

x = 0/log 2

x = 0

Also if P = 3

2^x = 3

x log 2 = log 3

x = log3/log 2

x = 0.4771/0.3010

x = 1.5850

Hence the positive value of x are 0 and 1.5850

Step-by-step explanation:

180-104 is 76 76-10=66 66/2 is 33

Answer: x = 33

Step-by-step explanation:

Well since that line is basically equal to 180 all you have to do is plug in those numbers for x. Since 33 + 10 = 43 Alll you gotta do is add that up. So we have 104 + 33 + 43 = 180. I’m not the best at explaining things but I hope this helped :)

Answer:

90

Step-by-step explanation:

The results of an independent-samples t test were t(19) = 4.02, p < 0.05. The sample size is 19.

The independent t-test is a defined as an statistical test in order to determine if we have statistically significant difference between the means of two unrelated groups.

Effect size is defined as a "quantitative measure of the magnitude of the experimenter effect" So, If we have a high value for the effect size then we can conclude that we have a stronger relationship between two variables.

T test is used to compare group means is one of the most common tests and is used to determine whether the means of two groups are equal to each other.

We perform one sample z-test;

One sample z-test is performed if the sample size is large enough (n  > 30) and we want to know if the sample comes from the specific population.

The results of an independent-samples t test were t(19) = 4.02, p < 0.05. In this example,

The sample size is 19.

Answer:

The set of five numbers would be {2,4,4,4,6}

Answer:

The example set could be:

S

=

{

2

,

4

,

4

,

4

,

6

}

See explanation.

Explanation:

First you can notice that if the set was:

S

1

=

{

4

,

4

,

4

,

4

,

4

}

then it would fulfill 2 conditions: mean and median, but

the set does not have the mode because all numbers are the same,

the range is zero (again all numbers are the same)

To have the mode the set would have to have at least one element different from

4

, but if we changed only one element the mean would change, so at least two numbers need to be changed to keep mean equal to

4

..

Now to get the range the difference between the changed numbers should be

4

. That leads us to adding two to one number and subtracting two from the other.

Finally we can get the set from the answer.

Answer:

Option C

Step-by-step explanation:

For the spinner,

Probability of spinning an even number = [tex]\frac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]

Favorable outcomes = even numbers on the spinner

                                   = 3

Total outcomes = Total numbers on the spinner

                          = 6

Probability of spinning an even number = [tex]\frac{3}{6}[/tex]

                                                                  = [tex]\frac{1}{2}[/tex]

For the cube,

Total outcomes = total numbers on the dice = 6

Favorable outcome = Odd numbers on the dice = 3

Probability of rolling an odd number on rolling a cube = [tex]\frac{3}{6}[/tex] = [tex]\frac{1}{2}[/tex]

Probability of spinning an even number on spinner and an odd number on a cube = [tex]\frac{1}{2}\times \frac{1}{2}[/tex]

         = [tex]\frac{1}{4}[/tex]

Percentage probability = [tex]\frac{1}{4}\times 100[/tex]

                                       = 25%

Answer:  450 cm squared if not including the inside surface

900 cm squared if including the inside suface

Step-by-step explanation:

A=2(wl+hl+hw)

A=2(150+90+60)

A=2(300)

A=600

but we have a lidless box so we need to subtract the lid...

600-(wl)=

600-(150)=450

If we are including the inside surface it would double as we would be covering both exposed surfaces of bottom, 2 ends, and 2 sides....

450x2=900

The surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

(i) The surface area will be calculated as,

A=2(wl+hl+hw)

A=2(150+90+60)

A=2(300)

A=600

But we have a lidless box so we need to subtract the lid.

600-(wl)=

600-(150)=450

(ii) If we are including the inside surface it would double as we would be covering both exposed surfaces of the bottom, 2 ends, and 2 sides.

450x2=900

Therefore, the surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.

Step-by-step explanation:

Okay, so I don't know what "do not include the units means", so I'm sorry if this is wrong, but the formula for the area of a parallelogram is height x width. Lucky for us, we have both so we just have to plug:

3.4 x 5.7 =   19.95

So, the area of the parallelogram is 19.95cm²
