Answer:

[tex] \sqrt{117} [/tex]

Step-by-step explanation:

Use the distance formula.

[tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] d = \sqrt{(-1 - 5)^2 + (3 - (-6))^2} [/tex]

[tex] d = \sqrt{(-6)^2 + 9^2} [/tex]

[tex] d = \sqrt{36 + 81} [/tex]

Step-by-step explanation:

Answer:

Yes, he can.

Step-by-step explanation:

Harper has two cans of paint that he would like to combine into one can.

One can contains 6.11 ounces and the other can contains 22.7 ounces.

The total quantity of paint he has is:

6.11 + 22.7 = 28.81 ounces

Since 28.81 ounces is lesser than 29 ounces, he can put both cans of paint into the 29 ounce can of paint.

Answer:

Gradient is -2/3 and y-intercept is -5/3.

Step-by-step explanation:

First, you have to make y the subject by moving all the unrelated terms to the other side :

[tex]3y + 2x + 5 = 0[/tex]

[tex]3y = - 2x - 5[/tex]

[tex]y = - \frac{ 2}{3} x - \frac{5}{3} [/tex]

Next, given that the slope-form equation is, y = mx+b where m is the gradient and b is the y-intercept. (*In a slope-form equation, gradient will always stick with x)

In the equation above, m is -2/3 and b is -5/3.

Answer: THe slope is 2 and y intercept is -3

Step-by-step explanation:

Answer:

Slope: 2

Y-intercept: -3

Step-by-step explanation:

The line is in point-slope form, or

y=mx+b

where m is the slope, and b is the y intercept

If we compare the 2 equations:

y=2x-3

y=mx+b

We can tell that the slope is 2, and the y-intercept is -3

Answer:

290 cm sq.

Step-by-step explanation:

We can approximate this irregular figure as a trapezoid.

We know the area formula for a trapezoid is A = (1/2)*(base1 + base2)*height

A = (1/2)* (22 cm + 36 cm) * (10 cm)

A = (1/2) *( 58 cm)*10 cm

A = 29 cm * 10 cm

A = 290 cm sq.

The answer should be 290 cm2, i will post a comment here later if it is wrong or not. Have a good day :)

Edit: It was correct

Answer:

i) 1000 cm³

ii) 614.125 cm³

Step-by-step explanation:

Volume of cube = side³

i) 10³ = 1000 cm³

ii) 8.5³ = 614.125 cm³

Answer:

1000 = 10^3

614.125 = 8.5^3

Since 24 = 8*3, we can factor out the GCF 8 like so

8x^2 - 24 = 8*x^2 - 8*3 = 8(x^2-3)

This is using the distributive property.

Answer:it didnt

Step-by-step explanation:

Answer:

m = 3

Step-by-step explanation:

First, distribute the 5 to the values inside the parentheses.

6 + 5m + 5 = 26

Combine like terms: 5m + 11 = 26

Then, you want to isolate the variable so you subtract 11 from both sides because what you do on one side must be done to the other.

5m + 11 - 11 = 5m

26 - 11 = 15

5m = 15

Then divide both sides by 5.

5m / 5 = m

15 / 5 = 3

m = 3

Answer:

m=3

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

Answer:

"Jeromar" give away more tickets

Step-by-step explanation:

What we must do is calculate the amount to which a ticket is equivalent, to do this, the value of the purchase must be divided by the number of tickets they give away, as follows:

"Colima"

150/4 = 37.5

In other words, they give away 1 ticket for $ 37.50

"Jeromar"

100/3 = 33.33

In other words, they give away 1 ticket for $ 33.33

Which means that "Jeromar give away more tickets, because the cost of the ticket is lower

Answer:

The function g(x) = (x + 1)² is represented by the graph Y

Step-by-step explanation:

The question presents the graph of the function x² above

Therefore, for a function f(x) = x² at x = 0 y = 0

For function g(x) = (x + 1)² when x = 0 g(x) = 1  Satisfied by graph W and Y

Also we have g(x) =  (x + 1)² = x² + 2·x + 1  or g(x) = f(x) + 2·x + 1

We find the minimum of the graph by differentiating and equating to zero as follows;

[tex]\frac{\mathrm{d} (x + 1)^{2}}{\mathrm{d} x} = 2x +2 = 0[/tex]

Therefor, the minimum is at x = -1 satisfied by only graph Y

Hence the graph that represents the function g(x) = (x + 1)² is the graph Y.

The arc measure BDC that subtend the angle at the center P of the circle is  213 degrees

The arc measure of angle BDC is as follows;

AC and BD are the diameter of the circle.

∠BPD ≅ ∠APD

Therefore,

4k + 159 = 2k + 153

4k - 2k = 153 - 159

2k = -6

k = -6 / 2

k = -3

4(-3) + 159 = 147°

∠BPD ≅ ∠APD = 147°

Hence,

∠BPA ≅ ∠CPD = 33°

arc BDC = 33 + 147 + 33 = 213 degrees

Answer:

sqrt(292) = JK

The approximate answer is

17.08800749 = JK

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

We know the legs JL and LK and are looking for the hypotenuse JK which is opposite and L which is the right angle

6^2 + 16^2 = JK ^2

36 +256 = JK ^2

292 = JK^2

Take the square root of each side

sqrt(292) = sqrt( JK^2)

sqrt(292) = JK

The approximate answer is

17.08800749 = JK

Answer:

2sqrt(73)

Step-by-step explanation:

Since angle L is 90, JK is the hypotenuse

JK² = 6² + 16²

JK² = 292

JK = 2sqrt(73)

Answer:

B. 17%

Step-by-step explanation:

The probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 is given by the z-score and P ( 0.37 < x < 0.39 ) = 16.32 %

The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.

The Z-score is calculated using the formula:

z = (x - μ)/σ

where z: standard score

x: observed value

μ: mean of the sample

σ: standard deviation of the sample

Given data ,

Let the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 be P ( A )

Now , the mean of the sample μ = 0.38

The standard deviation σ = 0.0485

And , z₁ = 0.37 and z₂ = 0.39

So , P ( A ) = P ( 0.37 < x < 0.39 )

On simplifying , we get

z = (x - μ)/σ

z₁ = ( 0.37 - 0.38 ) / 0.0485

z₁ = -0.206

z₂ = ( 0.39 - 0.38 ) / 0.0485

z₂ = 0.206

So , P ( 0.37 < x < 0.39 ) = P ( -0.206 < z < 0.206 )

On further simplification of the z-score , we get

P ( 0.37 < x < 0.39 ) = 0.5816045 - 0.4183955

P ( 0.37 < x < 0.39 ) = 0.1632

Hence , the probability is 16.32 %

Answer:

The median number of push-ups is 8.

Step-by-step explanation:

We use the median to find the "middle" value of a sample, that is, the value separating the lower half from the upper half of the sample.

If the size of the sample is even

1,2,3,4

Both the upper half and the lower half should have the same size.

In this case, it is not possible to select only one value which respects this condition. So the mean between 2 and 3 = 2.5 is calculated. This value is not part of the sample.

If the size of the sample is odd

1,2,3,4,5

For a n-sized sample, with n odd, the median is the value at the position (n+1)/2. So her, it is 3, the value at the third position. In this case, it is always going to be an element at a position in the sample, that is, an element of the sample.

In this question:

Initially, we list the number of pushups sorted in an increasing way.

6,8,8,14,18

The size of the sample is 5.

The median value is at the position (5+1)/2 = 3.

So it is 8, which is the element at the 3rd position.

Answer:

18

Step-by-step explanation:

The maximum number of push-ups that Justin did in a day this week was 18.

Answer:

x = -7/3y + 8/3

y = -3/7x + 8/7

Step-by-step explanation:

First, set the equations next to each other to find x and y, I'll start with x:

x + 3y + 2x + 4y = 8

Combine like terms

3x + 7y = 8

Subtract both sides by 7y

3x + 7y - 7y = 8 - 7y

3x = 8 - 7y

I'll re-order the equation to make it easier to divide

3x = -7y + 8

Divide both sides by 3

3x / 3 = -7y + 8 /3

x = -7/3y + 8/3

If you need decimals just divide with a calculator

Now to find y:

We already combined like terms so we don't need to do that again...

3x + 7y = 8

Subtract both sides by 3x

3x - 3x + 7y = 8 - 3x

7y = 8 - 3x

I'll reorder the equation once again so the variable comes first

7y = -3x + 8

Divide both sides by 7

7y / 7 = -3x + 8 / 7

y = -3/7x + 8/7

Again, use a calculator to divide completely for decimals.
