Answer:

[tex] m =\dfrac{-5}{7}[/tex]

Step-by-step explanation:

Given :-

And we need to find out the slope of the equation between the two points. The slope of the line passing through two points , is given by ,

[tex]\implies Slope (m) =\dfrac{ y_2-y_1}{x_2-x_1}[/tex]

[tex]\implies Slope (m) =\dfrac{ 11 - 6}{-2-5}\\\\\implies Slope = \dfrac{5}{-7} \\\\\implies Slope = \dfrac{-5}{7} [/tex]

Hence the slope of the line is -5/7 .

Answer:

C. only an obtuse isosceles triangle

Step-by-step explanation:

the triangle has two congruent(equal) angles that are both 32°, and a triangle with two congruent angles is an isosceles triangle.

the third angle, 126°, in the triangle is an obtuse angle because it is larger than 90°, and a triangle with one obtuse angle is an obtuse triangle

thus, the triangle with angle measures of 32, 126, and 32° is both an isosceles and obtuse triangle.

Step-by-step explanation:

For a function each input value can have one and only one output value

Therefor -17, -2, 5, 8 cannot be input values because they already have output values other than 9

Valid inputs are

Answer:

Percentage increase in the cost of his train ticket = 3% (Approx.)

Step-by-step explanation:

Given:

Cost of annual ticket paid by Patrick last year = £2,534

Cost of annual ticket paid by Patrick current year = £2,612

Find:

Percentage increase in the cost of his train ticket

Computation:

Percentage increase = [(Current - Base) / Base]100

Percentage increase in the cost of his train ticket = [(2,612 - 2,534) / 2,534]100

Percentage increase in the cost of his train ticket = [(78) / 2,534]100

Percentage increase in the cost of his train ticket = [0.03078]100

Percentage increase in the cost of his train ticket = 3.078

Percentage increase in the cost of his train ticket = 3% (Approx.)

Answer:

207.5 is the answer.

Step-by-step explanation:

Add up the numbers (207 + 208) = 415.

Then divide how many numbers, since the problem gives us 2 numbers, you divide 415 by 2.

That is how you find the mean.

Step-by-step explanation:

this is the correct

(A) delta h(t) = 32

Step-by-step explanation:

Average rate of change delta h(t) is given by

[tex]delta \: h(t) = \frac{h(b) - h(a)}{b - a} [/tex]

at t = 0, h(0) = 80

at t = 2, h(2) = -16(4) + 64(2) + 80 = 144

Plugging in the numbers

delta h(t) = (144 - 80)/(2 - 0)

= 32

Hello! answer: experimental probability 12/20

theoretical probability: 10/20

Answer:

[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

The rate of change is the change in y over the change in x. In this table, the change in y is +1, and the change in x is +3, so we get [tex]\frac{1}{3}[/tex]

Answer:

[tex]Range: \{y|y = -8,-6,0,8\}[/tex]

Step-by-step explanation:

Given

[tex]g(x) = 2x - 2[/tex]

[tex]x = \{x|-3,-2,1,5\}[/tex]

Required

The range using set notation

We have:

[tex]g(x) = 2x - 2[/tex]

When [tex]x = -3[/tex]

[tex]g(-3) = 2*-3 - 2 = -8[/tex]

When [tex]x = -2[/tex]

[tex]g(-2) = 2*-2 - 2 = -6[/tex]

When [tex]x = 1[/tex]

[tex]g(1) = 2*1 - 2 =0[/tex]

When [tex]x=5[/tex]

[tex]g(5) = 2*5 - 2 =8[/tex]

So, we have:

[tex]y = -8,-6,0,8[/tex]

Using set notation, the range is:

[tex]Range: \{y|y = -8,-6,0,8\}[/tex]

Answer:

C) At the 95% confidence level, the estimate of 0.48 is within 0.02 of the true proportion of county residents in favor of larger school zones in that county.

Step-by-step explanation:

x% confidence interval:

A confidence interval is built from a sample, has bounds a and b, and has a confidence level of x%. It means that we are x% confident that the population mean is between a and b.

In this question:

95% CI between 0.48 - 0.02 = 0.46 and 0.48+0.02 = 0.5.

The interpretation is that we are 95% sure that the true population proportion is in this interval, that is, with 95% confidence, the estimate is within 0.02 of the true proportion, and so the correct answer is given by option C.

Answer:

Step-by-step explanation:

The usual rules of rounding apply. If the digit in the 4th decimal place is 5 or more, then 1 is added in the 3rd decimal place. The roots are found using your calculator. The first 4 digits of the repeating decimal are clearly visible already.

a) √51 ≈ 7.141428... ≈ 7.141

b) 0.1326_26 ≈ 0.133

c) ∛971 ≈ 9.90238... ≈ 9.902

Answer:

12.56 m

Step-by-step explanation:

If the radius is 2, the the diameter will be 4 since the diameter = 2 radius. Next, you will multiply 3.14 * 4 to get your answer:

12.56 m

Answer:

7x-1/22 = 3x+1/10

Multiply both sides of the equation by the Lowest common Multiple of the denominators(22 and 10). This is done to clear the fractions.

The LCM of 22 and 10 is 110

So

110 x(7x-1/22) = 110 x (3x+1/10)

110/22 =5

110/10 = 11

So the eqn now becomes

5(7x-1) = 11(3x+1)

Opening the parentheses

35x - 5 = 33x + 11

Collect Like Terms

35x - 33x = 11 + 5

2x = 16

x= 8.

35 is the sum of the first five triangular numbers, making it a tetrahedral number. 35 is the number of ways that three things can be selected from a set of seven unique things also known as the "combination of seven things taken three at a time". ... 35 is the highest number one can count to on one's fingers using base 6.
