Answer:

465

Step-by-step explanation:

Hello! For this problem, you just plug in 7 everywhere you see u and then evaluate it! :)

[tex]10{u}^2-4u+3 \\\\u=7\\\\10(7)^2-4(7)+3 =\\\\10(49)-28+3 =\\\\490-28+3 =\\\\462+3 =\\\\465[/tex]

Answer:

First option.

Step-by-step explanation:

The mean of a set of data is all the data added together divided by the total numbers in that data set. So not only do you have to add an additional 45 to the data set, but you also have to divide the total of all the test scores by the total number of test takers which is now 31.

The range of a set of data is rearranging the data set smallest to largest and then subtracting the smallest from the largest value in the data set. Since the mean is 10 it's a small chance that 45 is either smallest or the largest of the set of data. We don't know the median, or the mode of the data set, nor does the question give us the other 30 test scores so it's between the range and the mean.

The most affected with the inclusion of the additional students test score would be the first option or the "mean."

Hope this helps.

Answer:

I'm pretty sure it's 0.08 km/minute

Step-by-step explanation:

r=4/50

4/50=0.08

Answer:

0.01 (nearest hundredth)

Step-by-step explanation:

[tex]\mathsf{probability=\dfrac{number \ of \ favorable \ outcomes}{number \ of \ total \ outcomes}}[/tex]

Total number of marbles (total outcomes) = 2 + 6 + 7 = 15

⇒ Probability of the first marble being red = [tex]\dfrac{2}{15}[/tex]

As there is no replacement, the total number marbles is now 15 and there is only 1 red marble left.

⇒ Probability of the second marble being red = [tex]\dfrac{1}{14}[/tex]

So the probability of the 1st and 2nd marble being red is:

[tex]\dfrac{2}{15}\times \dfrac{1}{14} = \dfrac{1}{105}[/tex]  = 0.01 (nearest hundredth)

Answer:

I put the answer on your copy of this question. However, I can at least put the equation here.

You are correct in this case.

11 + 9 = 20 - 9 = 11

11 plus 9 equals 20, 20 minus 9 equals 11 (correct statement)

Step-by-step explanation:

[tex] {x}^{o} + {115}^{o} + {95}^{o} + {70}^{o} = {360}^{o} \\ [/tex]

(The measure of the interior angle of a square is 90°)

[tex]{x}^{o} + {115}^{o} + {95}^{o} + {70}^{o} = {360}^{o} \\ {x}^{o} + {280}^{o} = {360}^{o} \\ {x}^{o} = {360}^{o} - {280}^{o} \\ {x}^{o} = {80}^{o} \\ [/tex]

Answer:

45

Step-by-step explanation:

180/1 × 1/4

common factor 4

180÷4=45

990 = 1000 - 10

so 3 x 990 = 3 x (1000 - 10) = 3 x 1000 + 3 x (-10) = 3000 - 30 = 2970

and

990 = 900 + 90

so 3 x 990 = 3 x (900 + 90) = 3 x 900 + 3 x 90 = 2700 + 270 = 2970

To show that the equations are the same, we need to rewrite one of the equations as an equivalent equation of the second

Damita's claim is true

The equations are given as:

0.8x - 0.8 = 1.6

4/5 ( x - 1 ) = 1 (3/5)

We need to rewrite one of the equations, as follows:

4/5 ( x - 1 ) = 1 (3/5)

Express as decimal

0.8 ( x - 1 ) = 1 + 0.6

Open the brackets

0.8x - 0.8 = 1.6

Now we have:

0.8x - 0.8 = 1.6 (the first equation) and 0.8x - 0.8 = 1.6 (the equivalent of the second equation)

The above shows that both equations are the same

Step-by-step explanation:

1) 10, 2, 1.2, 1.12, 1.112, 1.1112

[tex]t_n=\dfrac{t_{n-1}}{10}+1[/tex]

t₁ = 10

t₂ = 10/10 + 1    = 2

t₃ = 2/10 + 1     = 1.2

t₄ = 1.2/10 + 1   = 1.12

t₅ = 1.12/10 + 1  = 1.112

t₆ = 1.112/10 + 1 = 1.1112

2)  10, 2, -2, -4, -5, -5.5, ...

[tex]t_n=\dfrac{t_{n-1}}{2}-3[/tex]

t₁ = 10

t₂ = 10/2 - 3 =   2

t₃ = 2/2 - 3  =  -2

t₄ = -2/2 - 3 =  -4

t₅ = -4/2 - 3 =  -5

$13.95

Step-by-step explanation:

$166.29 ×12/100

=$13.95 will be the tip.

Answer:

$13.95

Step-by-step explanation:

Convert the 12% to an actual number that can be used in a calculator. For percents, this is done by dividing the percent (in this case 12%) by 100%.So, the conversational term "12%" becomes 12% / 100% = 0.12 in terms of a real mathematical number. Then you need to find out what 12% of your $116.29 meal cost is.This is always done by multiplying 0.12 by $116.29, or 0.12 x $116.29=$13.95.

Answer:

The critical value  is  [tex]t_{\frac{0.10}{2} , 14 } =[ - 1.761,1.761][/tex]

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  15

   The  level of significance is  [tex]\alpha = 0.10[/tex]

The null hypothesis is  [tex]H_o : \mu _1 = \mu_2[/tex]

The alternative hypothesis is  [tex]H_a : \mu_1 \ne \mu_2[/tex]

Here [tex]\mu_1[/tex] is average time for previous year

        [tex]\mu_2[/tex] is the average time for current year

Generally the degree of freedom is mathematically represented as

         [tex]df = n -1[/tex]

=>      [tex]df = 15 - 1[/tex]

=>     [tex]df = 14[/tex]

Generally from the student  t distribution table the critical value  for [tex]\frac{\alpha }{2}[/tex] at a degree of freedom of  [tex]df = 14[/tex] for a two tailed test  is

Is ther a question to this

Answer:

Question 1 read explanation. Question 2 it's c= 5. Question 3 it's 5 miles. Question4 it's

Step-by-step explanation:

For question 1 it's just asking you to make a right triangle with the segment as the hypotenuse. To do that make a dot on (5,1) and draw the triangle. A hypotenuse is the longest side of a right triangle, opposite the right angle.

For question 2 you just get the units of the triangle. The hypotenuse is always c (the segment). However, it's difficult to find c by just looking at the graph. That's why you plug in the other sides a = 3 and b = 4 (doesn't matter which way) to find c. So, you plug in 3^2 + 4^2 = c^2. This will give 9 + 16 = c^2, which is 25 = c^2. We need c not c^2! That means we square 25 to get 5. c = 5!

For question 3, you use the answer from question 2 I believe, so it's 5 miles.

For question 4, it's the same as question 1 so if it helps you make a visual on paper. Draw those two dots and to make a right triangle you'll also need the point (1,1). Find the units 8^2 + 10^2 = c^2. c =  2root41.
