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)

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.

Answer:

0. 5

Step-by-step explanation:

its lyk two × 1 equals to 2 divide by 4

Step-by-step explanation:

(2×1)÷4. multiply 2 by 1 according to BEDMAS Rule

2÷4. Divide 2 by 4

0.5.

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

Answer:

45

Step-by-step explanation:

180/1 × 1/4

common factor 4

180÷4=45

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:

x=1

Step-by-step explanation:

You might want to be saving money by using less energy and less water by not growing plants. You can also buy only essential items and leave the items you want for later. You can also get a car that uses less gas per gallon.

Answer:

Don’t but junk food, anything from a deli/store. Don’t waste water or gas. But things that you will actually use and will last for looong time. Put your money into a savings account. Just don’t buy anything that not nesscary even if it looks cool, save your money. Find cheap but good quality  (ex. Apartment, furniture, etc.).

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  

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

Answer:

1)6 3/4

2)2 4/7

3)5/6

4)1 2/15

Step-by-step explanation:

Let's start off by defining our first term as u⁰

u⁰ is unknown,u¹=3124,u² is unknown,ect..

Using the recurring formula which states;

u(n+1)=u(n)+d

u¹=u⁰+d

u⁰=u¹-d

u⁰=3125-d

Using the explicit relation, which states;

u(n)=u⁰+nd

u⁵=u⁰+5d

5=3125-d+5d

4d=-3120

d=-780

u²=u¹-780=3125-780=2345

u³=2345-780=1565

u⁴=1565-780=785

You answer is letter C

The arithmetic means of the given sequence is 2455, 1675, 895

let the first term be u(0).

and, first term u(1) = 3124

We can use the recurring formula as:

u(n+1)=u(n)+d

u(1)=u(0)+d

and, u(0)=u(1)-d

and, u(0)=3125-d

Using the explicit relation

u(n)=u(0)+nd

u(5)=u(0)+5d

5=3125-d+5d

4d=-3120

d=-780

and, u(2)=u(1)-780

u(2) = 3125-780

u(2) = 2345

and, u(3)=2345-780

u(3) =1565

and, u(4)=1565-780

u(4) = 785

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)

Step-by-step explanation:

r=4/50

Answer:  see below

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

t₆ = -5/2 - 3 = -5.5
