What is the slope of the line?

Answer:

D

Step-by-step explanation:

D)

13% of x is 2600

13% = 13/100

⇒ (13/100)x = 2600

⇒ 13/100 = 2600/x

FYI A) gives the same value of x as D)

option A [tex](4, \frac{7}{2})[/tex] is the midpoint.

Explanation:

To find midpoint: [tex](\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})[/tex]

We shall use this formula here:

[tex](\frac{9+-1}{2}, \frac{5+2}{2})[/tex]

[tex](\frac{8}{2}, \frac{7}{2})[/tex]

Use x=3 in the equation.

  -25x +y = 65

  y = 65 +25x = 65 +25(3) = 140

Answer:

C. 52.5cm^2

Step-by-step explanation:

Area of a triangle - A=1/2bh  or  area=1/2 base times height

Area of a rectangle -  A=lw   or area=length times width

Separate the shapes first, you would draw a line between the two if this was on paper.

Find the separate areas.
Rectangle area:

8*5=40

Triangle area:

find the height first. the height of this triangle is the same as the length of the rectangle minus the 1 and 2 cms.

8-1-2=5

1/2*5*5=12.5

Now add the areas:

40+12.5=52.5cm^2

Step-by-step explanation:

THE answer is 6

First Calculate the number of action figures sold on Monday:

8 comic books for every 3 action figures

32 comic books =? action figures

8 x 4 = 32

so, 3 x 4 = 12 action figures sold on Monday

next Find the difference between the number of action figures sold on Monday and Tuesday

They're asking for the difference, so you subtract

18 - 12 = 6

Hence, the difference in the number of books on Monday and Tuesday is 6

Answer:

3.875

Step-by-step explanation:

I just kinda know I'm good with cups and gallons

I don't know what kind of calculator you have at your disposal, so I'll just give one way of computing the sample mean and standard deviation.

• To get the mean, add up all the data points and divide the total by the number of data:

[tex]\bar x = \displaystyle \sum_i \frac{x_i}n = \frac{1243+1264+\cdots+1275}9 \approx 1273.89 \\ \implies \boxed{\bar x \approx 1274}[/tex]

• To get the s.d. s, first compute the variance s² by adding up the squared difference between each of the data points and the sample mean, and divide the total by 1 less than the number of data:

[tex]s^2 = \displaystyle \sum_i \frac{\left(x_i-\bar x\right)^2}{n-1} = \frac{(1243-1274)^2+(1264-1274)^2+\cdots+(1275-1274)^2}8 \approx 1211.61[/tex]

The s.d. is the square root of the variance:

[tex]s^2 \approx 1211.61 \implies s \approx 34.8082 \implies \boxed{s\approx 35}[/tex]

The 90% confidence interval for the sample mean has upper and lower limits, respectively, of

[tex]\bar x \pm \dfrac{\left|Z_{\alpha/2}\right| s}{\sqrt n}[/tex]

(positive root for upper limit, negative root for lower limit)

where [tex]Z_{\alpha/2}[/tex] is the critical value for a (1 - α)×100% confidence level. By critical value, I mean

[tex]\mathrm{Pr}\left[ Z \le Z_c \right] = c[/tex]

where Z is a random variable following the standard normal distribution.

In this case, we have a 90% confidence level, so α = 0.1, and the critical value is [tex]Z_{0.05} \approx -1.64[/tex]. Then the confidence interval has upper limit

[tex]\bar x + \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 + \dfrac{1.64 \times 35}{\sqrt9} \approx 1292.97 \approx \boxed{1293}[/tex]

and lower limit

[tex]\bar x - \dfrac{\left|Z_{0.05}\right|s}{\sqrt n} = 1274 - \dfrac{1.64 \times 35}{\sqrt9} \approx 1254.8 \approx \boxed{1255}[/tex]

He caught 22 but put 5 back so had 22-5 = 17 fish

He then caught 12 more for a total of 17 + 12 = 29

Answer: 29 fish.

Answer:

The answer is 29 (so you were right!)

Step-by-step explanation:

He had 22 fish, and he threw 5 back

22 - 5 = 17

He caught 12 more in the afternoon

17 + 12 = 29

So, 29 is your answer.

Step-by-step explanation:

Yes these side lengths can make a triangle

The triangle side length rule states that any 2 sides of a triangle are greater than the other side.

Let's use this rule to determine if these side lengths can make a triangle.

4+7=11 and 11 is greater than 10.

4+10=14 and 14 is greater than 7.

7+10=17 and 17 is greater than 4.

These side lengths can make a triangle.

Answer:

700 by 70

Step-by-step explanation:

The equation for perimeter is 2(l + w). Since the length has an assigned value, l will become 10w.

2(10w + w) = 1540

First, add the parenthetical expression to get 11w.

2(11w) = 1540

Now, DISTRIBUTE! 2(11w) becomes 22w.

22w = 1540

Lastly, divide by 22 to get 70. You can also say that this could be 22w = 154 * 10. 22 * 7 is 154 (140 + 14), and 7 * 10 is 70.

w = 70

Now that we know the width, substitute 70 for w in the 10w expression.

l = 10(70)

Just multiply and you'll get 700.

l = 700

Now we know the dimensions to be 700 * 70 (or 70 * 700; I just prefer to put the length first)
