Answer:

7

Step-by-step explanation:

An integer can be a whole number or a whole negative number. 6.782 is the answer but because we have to put it into an integer I rounded it to 7.

Answer:

60 degrees

Step-by-step explanation:

Vertical angles are angles opposite of each other created by intersecting lines.

Vertical angles are always congruent ( equal ) to each other.

So if an angle has a measure of 60 degrees then its vertical angle would also have a measure of 60 degrees

Answer:

60°

Step-by-step explanation:

Vertical angles are angles of the same measure.

One of the vertical angles is 60°. Therefore, the other angle must be 60°.

Using the normal distribution, it is found that there is a 0.84 = 84% probability that a randomly selected high jumper has a personal best between 227 and 265 cm.

The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given, respectively, by:

[tex]\mu = 208, \sigma = 19[/tex]

The probability that a randomly selected high jumper has a personal best between 227 and 265 cm is the p-value of Z when X = 265 subtracted by the p-value of Z when X = 227, hence:

X = 265:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{265 - 208}{19}[/tex]

Z = 3

Z = 3 has a p-value of 0.9987.

X = 227:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{227 - 208}{19}[/tex]

Z = 1

Z = 1 has a p-value of 0.1587.

0.9987 - 0.1587 = 0.84.

0.84 = 84% probability that a randomly selected high jumper has a personal best between 227 and 265 cm.

Answer:

The answer is B, 396 square units.

Step-by-step explanation:

We can separate the figure into five individual polygons and sum up their areas to find the total surface area of the figure.

The base of the figure is 8*12 = 96.

The rectangle at the back of the figure is 8*9 = 72.

To find the area of the rectangle on top, we need to first find second side length. To do this, we use the pythagorean theorem (a^2 + b^2 = c^2) on the right triangle, so 9^2 + 12^2 = c^2 --> 225 = c^2 --> c = 15. Next, we find the area of the rectangle which is 8*15 = 120.

The area of the triangle to the side is 1/2*12*9 (9 is height because it's a right triangle) = 54, so the area of both triangles is 54*2 = 108.

Now we sum up the areas: 96 + 72 + 120 + 108 = 396

Answer:

200.96

Step-by-step explanation:

2(3.14)2^2 + 2(3.14)2*14

8*3.14 = 25.12

56*3.14 = 175.84

175.84 + 25.12 = 200.96

Step-by-step explanation:

1. You have to find the gradient / slope from y = 5x + 20

y = 5x + 20

y = mx + c

With using a general form, we known that the gradient of the line is 5.

2. Use the formula "[tex]y - y_1 = m.(x - x_1)[/tex]" to find the line.

[tex]y - y_1 = m.(x - x_1)[/tex]

[tex]y - 10 = 5.(x - 0)[/tex]

[tex]y = 5x - 0 + 10[/tex]

[tex]y = 5x + 10[/tex]

Answer:

y = 5x + 10.

Step-by-step explanation:

Y = 5x + 20

The gradient m = 5

So the line parallel to it has a gradient of 5 also.

Using the point slope form of straight line:

y - y1 = m(x - x1)

Here,  m = 5, x1 = 0 and y1 = 10:

y - 10 = 5(x - 0)

y - 10 = 5x

y = 5x + 10.

So the vector [tex]j[/tex] represents 1 mile per hour south.

Maria is jogging south at 12 miles per hour.

Therefore, the vectors [tex]12j[/tex] represents Maria's velocity. The correct answer is B.

The vector used to represent the position of Maria is -12j.

A measurement with a magnitude and direction. It is often represented by an arrow whose length is proportional to the magnitude of the quantity and whose direction is the same as that of the quantity. A vector does not have position, while having magnitude and direction.

Given:

vector i represents 1 mile per hour east

and, vector j represents 1 mile per hour north

Now, the position of north is opposite to south

The solution of the quadratic equation is irrational because 11² - 4*3*9 is not a perfect square.

An irrational quadratic equation is an equation that contains two irrational solutions making the equation not to be able to be solved through factorisation.

Using the quadratic equation formula to solve, the irrational solutions are gotten below,

X = -b +√b²- 4ac/2a

where a = 3; b= 11 ; C = 9

X = -3+√11²-4*3*9/2*3

X= -3+√ 121-108/6

X= -3 +√13/6

X =-3/6 +√13/6

X= -1/2 + √13/6
