Answer: 2

Step-by-step explanation:

Answer:

To find the value of x, add 5 to each side.

x - 5 = 13

+5 +5

x = 18

Answer:

2/ triple need video for the third answer

Step-by-step explanation:

Answer:

Step-by-step explanation:

If you round it to the nearest whole number, then 17.526  becomes 18 because if the first digit after the decimal(in this case,5) is 5 or greater you round to the next whole number.

If you round it to the nearest tenth, it would result in 17.5, because if the second digit after the decimal (in this case, 2) is 5 or greater you round to the next tenth of decimal.

Hope this helps!

Answer:

Step-by-step explanation:

It can be rounded down to 17.5 if rounding to 1 decimal place. If you are rounding to the nearest whole number, you would round to 18.

Hope this helps :)

Answer:

x=64°

................

=============================================================

Explanation:

Combining all of the angles shown in the diagram leads to 360 degrees. This is because there are 360 degrees in a full rotation.

Let's add up the angles shown and set the sum equal to 360. Keep in mind that the square angle marker represents 90 degrees (aka a right angle).

180+26+x+90 = 180

x+296 = 360

x = 360-296

x = 64

Answer:

31.3%

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Five trials, probability of a success is 50%.

This means that [tex]n = 5, p = 0.5[/tex]

Probability of exactly two successes

This is P(X = 2). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{5,2}.(0.5)^{2}.(0.5)^{3} = 0.313[/tex]

0.313*100% = 31.3%

Answer:

P(2 and B) = [tex]\frac{1}{24} = 0.0417[/tex]

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, the events getting a 2 and the letter B are independents, so we find each separate probability and multiply them.

Probability of getting a 2:

8 possible values on the spinner, one of which is 2. So

[tex]P(A) = \frac{1}{8}[/tex]

Probability of getting a B:

6 possible values, two of which are B. So

[tex]P(B) = \frac{2}{6} = \frac{1}{3}[/tex]

P(2 and B)?

[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{8}*\frac{1}{3} = \frac{1}{8*3} = \frac{1}{24} = 0.0417[/tex]

P(2 and B) = [tex]\frac{1}{24} = 0.0417[/tex]

Width of rectangle = 5 inch

Length of rectangle = 2 inch

Step-by-step explanation:

Given:

Area of rectangle = 10 inch²

Length of rectangle = 2[Width of rectangle] - 8

Find:

Equation

Value of length and width

Computation;

Assume;

Width of rectangle = x

So,

Length of rectangle = 2[Width of rectangle] - 8

Length of rectangle = 2x - 8

Area of rectangle = Length × Width

10 = x(2x - 8)

2x² - 8x - 10 = 0

Divide by 2 from both side

x² - 4x - 5 = 0

x² - (5-1)x - 5 = 0

x² - 5x + x- 5 = 0

x(x - 5) + 1(x - 5)

x = 5 and x = -1

So,

Width of rectangle = 5 inch

Length of rectangle = 2x - 8

Length of rectangle = 2(5) - 8

Length of rectangle = 2 inch

Answer:

-8

Step-by-step explanation:

Plug in -4 for w,  2(-4)2+8     (2x-4x2+8)

2 x -4 x 2 =-16

Answer:

D) 54.9 cm^2

Step-by-step explanation:

I found the area of the circle wwith the formula A= πr^2

A= π•64

then I found the area of the square, 256

then I subtracted the area of the circle from the area of the square and got approx. 54.9

Answer:

<A = 45°

<B = 110°

Step-by-step explanation:

Sum of the interior angles of a triangle = 180°

Therefore,

(x + 65)° + 25° + x° = 180°

Solve for x

x + 65 + 25 + x = 180

Add like terms

2x + 90 = 180

2x = 180 - 90

2x = 90

x = 90/2

x = 45°

✔️x + 65 = 45 + 65 = 110°

<A = x = 45°

<B = 110°

Answer:

amita can only use and it is only 2

2

Answer:

Step-by-step explanation:

Given,

Base of the parallelogram = 10

Height of the parallelogram = 12

Therefore,

Area of the parallelogram = base × height

= 10 × 12

= 120

Hence,

Area of the parallelogram is 120 square units (Ans)

Answer:

Var = 6.31

Step-by-step explanation:

The Value at Risk (VAR)

[tex]P(X < x_o) = 0.01[/tex]

By using normal distribution

Mean [tex]\mu[/tex] = 10

Variance = 49

Standard deviation [tex]\sigma = \sqrt{49 } = 7[/tex]

This implies that:

[tex]P\Big ( \dfrac{X - \mu}{\sigma } < \dfrac{x_o - \mu }{\sigma}\Big) = 0.01 \\ \\ P\Big ( Z < \dfrac{x_o - \mu }{\sigma}\Big) = 0.01 \\ \\ \dfrac{x_o - \mu }{\sigma} = invNorm(0.01) \\ \\ x_o = \mu + \sigma \times invNorm (0.01)[/tex]

Using the z-table;

[tex]x_o = 10 + 7 \times (-2.33) \\ \\ x_o = -6.3100[/tex]

Hence, there exist 1% chance that X < -6.31 or the loss from investment is > 6.31

From the calculated value above;

[tex]V = \mu -\sigma \times 2.33[/tex]; Since the result is negative, then it shows that the greater the value(i.e the positive or less negative it is ) the lower is the value of VAR. Thus, the least value of VAR is accepted by  the largest value of

[tex]min( \mu -\sigma \times2.33,0)[/tex]

Step-by-step explanation:

Answer:

TE = 12

Step-by-step explanation:

Given:

TE = 4 + 2x

EV = 4x - 4

The diagonals of the figure bisects each other. This means that:

TE = EV

4 + 2x = 4x - 4

Collect like terms

2x - 4x = -4 - 4

-2x = -8

Divide both sides by -2

x = -8/-2

x = 4

✅Find TE:

TE = 4 + 2x

Plug in the value of x

TE = 4 + 2(4)

TE = 4 + 8

TE = 12

Answer:

x = 16

Step-by-step explanation:

I could be wrong so sorry in advance lol but this is what I did:

I made the equation 3x + 3 = ((7x-10)/2)

I divided the 2nd equation by 2 so that it would be the same length as RZ.

after that, I got: 3x + 3 = 3.5x - 5

from there, i did basic algebra to get the answer 16
