Answer:x=10

Step-by-step explanation:

5/2 × 2/5 = 4/1 × 5/2

Multiply and simplify and x=10

The solution to the equation 2/5x = 4 is x = 10. You can find the solution by multiplying both sides of the equation by 5/2, which cancelled out the 2/5 on the left side, and then performing the operation on the right side.

To solve the equation 2/5x = 4, you'll first want to isolate the variable 'x' on one side of the equation. You can do this by dividing both sides of the equation by the coefficient of 'x', which is 2/5. However, instead of dividing by a fraction, it's easier to multiply by the reciprocal of the fraction.

So, we multiply both sides of the equation by 5/2. The 5/2 multiplied by 2/5 on the left side of the equation equals 1, leaving us with just 'x' on the left side of the equation.

So, you would have x = 4 * 5/2.

Now, we just perform the operation on the right side to find the value of 'x', and we get x = 20/2 = 10.

So, the solution to the equation 2/5x = 4 is x = 10.

Answer:

There is a 7/10 chance that it is not white

Step-by-step explanation:

To find this, start by finding the number of total shirts.

9 + 6 + 5 = 20

Now find the number that are not white.

9 + 5 = 14

Now divide the number of non-white by the number in total.

14/20

And simplify the fraction.

7/10

Final answer:

The probability of choosing a shirt that is not white from the drawer is 7/10, since there are 14 non-white shirts out of a total of 20 shirts.

Explanation:

The question asks to find the probability that a shirt chosen at random from a drawer is not white, given that there are 9 black shirts, 6 white shirts, and 5 gray shirts. To tackle this, we'll look at the total number of shirts and then subtract the number of white shirts from this total to find how many shirts are not white. The total number of shirts is 9 (black) + 6 (white) + 5 (gray) = 20 shirts. The number of shirts that are not white would be 20 (total) - 6 (white) = 14 shirts. Therefore, the probability of choosing a non-white shirt is 14 (non-white shirts) divided by 20 (total shirts), which simplifies to 7/10. This fraction is already in its simplest form.

Answer:

[tex]x=\frac{2}{5}[/tex] or [tex]x=1[/tex]

Step-by-step explanation:

The given quadratic equation is

[tex]5x^2-7x+2=0[/tex]

Group the constant terms on the right hand side.

[tex]5x^2-7x=0-2[/tex]

[tex]5x^2-7x=-2[/tex]

Divide through by 5.

[tex]x^2-\frac{7}{5}x=-\frac{2}{5}[/tex]

Add the square of half the coefficient of x., which is [tex](\frac{1}{2}\times- \frac{7}{5})^2=\frac{49}{100}[/tex] to both sides of the equation.

[tex]x^2-\frac{7}{5}x+\frac{49}{100}=-\frac{2}{5}+\frac{49}{100}[/tex]

The left hand side is now a perfect square.

[tex](x-\frac{7}{10})^2=\frac{9}{100}[/tex]

Take the square root of both sides;

[tex](x-\frac{7}{10})=\pm \sqrt{\frac{9}{100}}[/tex]

[tex]x-\frac{7}{10}=\pm \frac{3}{10}[/tex]

[tex]x=\frac{7}{10}\pm \frac{3}{10}[/tex]

[tex]x=\frac{7-3}{10}[/tex] or [tex]x=\frac{7+3}{10}[/tex]

[tex]x=\frac{4}{10}[/tex] or [tex]x=\frac{10}{10}[/tex]

[tex]x=1[/tex] or [tex]x=\frac{2}{5}[/tex]

Answer:

[tex]x_1=1\\\\x_2=\frac{2}{5}[/tex]

Step-by-step explanation:

- You must divide the equation by 5:

[tex]x^{2}-\frac{7}{5}x+\frac{2}{5}=0[/tex]

- Add and subtract [tex](\frac{\frac{7}{5}}{2})^2[/tex]:

 [tex]x^{2}-\frac{7}{5}x+(\frac{7}{10})^2+\frac{2}{5}-(\frac{7}{10})^2=0[/tex]

Therefore, you obtain:

[tex](x-\frac{7}{10})^2-0.09=0[/tex]

-add 0.09} to both sides:

[tex](x-\frac{7}{10})^2=0.09[/tex]

- Apply square root to both sides and solve for x:

[tex]\sqrt{(x-\frac{7}{10})^2}=\sqrt{\0.09}\\x-\frac{7}{10}=\sqrt{0.09}\\\\x_1=\frac{7}{10}+\sqrt{0.09}=1\\\\x_2=-\frac{7}{10}-\sqrt{0.09}=\frac{2}{5}[/tex]

Step-by-step explanation:

The five-number summary includes five things that are:

1. Minimum Value

2. First Quartile (Q₁)

3. Median

4. Third Quartile (Q₃)

5. Maximum Value

So, Firstly arrange given data in ascending order:14, 18, 28, 29, 32, 44, 48, 50, 65

1. Minimum Value = 14

It can be found by arranging the data in ascending order, the first value we will get is the minimum value.

2. First Quartile is the middle value between Minimum value and Median of data after arranging data in ascending order.

First Quartile (Q₁) = 28

3. Median is the middle value of the data after arranging them in ascending order.  

Median = 32

4. The third Quartile is the middle value between Median and Maximum Value of data after arranging data in ascending order.

Third Quartile (Q₃) = 48

5. Maximum Value is the largest value of the data or is the last value after arranging the data in ascending order.

Maximum Value = 65.

Answer:

A) A

Step-by-step explanation:

The equation of a line is given by

[tex]y=mx+q[/tex]

where

m is the slope of the curve

q is the y-intercept of the curve

The two lines given in the problem are:

[tex]y=\frac{4}{3}x+2[/tex] --> slope of 4/3 and y-intercept of +2

[tex]y=5x[/tex] --> slope of 5 and y-intercept of 0

By exclusion, we see that the correct answer is A. In fact:

- Option B is wrong, because one of the two lines has negative slope, while the two lines given in the problem have both positive slope

- Option C is wrong, because one of the two lines is flat (slope=0), while none of the two lines given in the problem has a slope of zero

- Option D is wrong, because again one of the two lines has negative slope

Option A is the correct one: in fact, we see that the black line has an y-intercept of +2 and a slope of 4/3, while the green line has a slope of 5 and an y-intercept of zero.

Answer:

1. Option A

2. Option B

3. Option D

4. Option C

Step-by-step explanation:

The given vertices of triangle ABC are A(-3, 6), B(2,1), C(9, 5).

We have to fine the distance AB, BC and AC.

To calculate the distance between two vertices we will use the formula

[tex]d=\sqrt{(x-x')^{2}+(y-y')^{2}}[/tex]

For the length of side AB

AB=[tex]\sqrt{(2+3)^{2}+(1-6)^{2}}=\sqrt{5^{2}+5^{2}}=\sqrt{50}[/tex]

Option A. is the correct option

For the length of side BC

[tex]BC=\sqrt{(9-2)^{2}+(5-1)^{2}}=\sqrt{7^{2}+4^{2}}=\sqrt{65}[/tex]

Option B is the answer.

For the length of side AC

[tex]AC=\sqrt{(9+3)^{2}+(5-6)^{2}}=\sqrt{12^{2}+(-1)^{2}}=\sqrt{145}[/tex]

Option D is the answer.

For ∠ABC we will use the formula [tex]tan\theta =\frac{m_{1}-m_{2}}{1+m_{1}m_{2}}[/tex]

Since angle ABC is formed by two sides AB and BC

So we will find the slopes of these two lines and find the angle

Now slope of AB, [tex]m_{1}=\frac{y-y'}{x-x'}=\frac{1-6}{2+3}=\frac{-5}{5}=-1[/tex]

Slope of BC, [tex]m_{2}=\frac{5-1}{9-2}=\frac{4}{7}[/tex]

[tex]tan\theta =\frac{m_{1}-m_{2}}{1+m_{1}m_{2}}[/tex]

[tex]tan\theta =\frac{(-1)-(\frac{4}{7})}{1+(-1)(\frac{4}{7})}=\frac{\frac{-11}{7}}{1-\frac{4}{7}}=\frac{\frac{-11}{7}}{\frac{3}{7}}=\frac{-11}{7}\times \frac{7}{3}=-\frac{11}{3}=-3.67[/tex]

[tex]\theta =tan^{-1}(-3.67)=74.75[/tex]

Since angle between them [tex]tan\theta[/tex] is negative that means angle theta will be obtuse angle.

So the angle between AB and BC = (180 - 74.75) = 105.26°

Therefore Option C. 105.26° is the answer.

Answer:  4h - 3

Step-by-step explanation:

replace "x" with "h - 1" and simplify

f(x) = 3x + h

f(h - 1) = 3(h - 1) + h

          = 3h - 3 + h

          = 4h - 3

Answer:

Step-by-step explanation:

Triangles

Area of a triangle = 1/2 b * slanted height

b = 6 m

h = 9 m

Area of 1 triangle = 1/2 * 6 * 9

Area of 1 triangle = 27

Area of all 4 triangles = 4*27 = 108 m^2

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

Base area

The base is a square. All 4 sides are equal.

The formula for a square is s^2

Area = (6 m)^2

Area = 36 m^2

Total area

Total Area = 108 m^2 + 36 m ^2

Total Area = 144 m^2

your answer is 144m2

Answer:

907,450

Step-by-step explanation:

This is a problem of exponential decay. The population is decreasing at 0.1% per year.

The formula to figure this out is  [tex]A=P(1+r)^t[/tex]

Where

A will be the future population (after 50 years)

P is the initial population (which is 954,000)

r is the rate of decrease (which is -0.1% or -0.001)

t is the time in years (which is 50)

Plugging these information into the formula and figuring out A will give us the answer. Shown below:

[tex]A=P(1+r)^t\\A=954,000(1-0.001)^{50}\\A=954,000(0.999)^{50}\\A=907,450.17[/tex]

Since fractional/decimal population is not feasible, we round it off.

The population in 50 years would be around 907,450

It means that [tex][/tex] is greater than [tex]a[/tex] (b > a) so it is true.

Answer:

16

2

Step-by-step explanation:

Given in the question an equation

[tex]\frac{x^2 - 10x + 14}{ x-8}[/tex]

The constant term that the numerator must have = 16

To get this number add 2 in the numerator

after which the equation will become

[tex]\frac{x^2 - 10x + 14+2}{ x-8}[/tex]

[tex]\frac{x^2 - 10x + 16}{ x-8}\\[/tex]

Now by using factorisation of quadratic equation we have

[tex]\frac{(x-8)(x-2)}{x-8}[/tex]

(x-2)

but if we add and subtract 2 in the numerator then

[tex]\frac{x^2 - 10x + 16 -2}{ x-8}[/tex]

[tex]\frac{(x-8)(x-2)-2}{x-8}[/tex]

[tex](x-2)-\frac{2}{x-8}[/tex]

Step-by-step explanation:

In this experiment, the ratio of heads to tails comes out to be 2/1.

Probability is a way to gauge how likely something is to happen. Even while no event can be foreseen with absolute certainty, probability can be used to convey how likely it is that it will happen.

Probability is the ratio of the number of favourable outcomes to the total number of outcomes of an event.

The number of favourable outcomes for an experiment with 'x' and the total outcomes is represented by the symbol 's'. The following formula can be used to determine how likely an event is to occur.

Probability = Favourable Outcomes/Total Outcomes = x/s

The total number of the outcomes are 36.

The total outcome for head is 24 times.

So, the total outcome for tail will be 36 - 24 = 12

The ratio of head to tail is = favourable outcome for heads/ favourable outcomes for tails.

Thus,

heads/ tails = 24/12

heads/tails = 2/1

Therefore, the ratio of heads to tails in the experiment is 2/1.
