[tex]\boxed {x = -15}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]x + 7 = -8[/tex]

-Subtract both sides by [tex]7[/tex]:

[tex]x + 7 - 7 = -8 - 7[/tex]

[tex]\boxed {x = -15}[/tex]

So, the value of [tex]x[/tex] is [tex]-15[/tex].

Answer:

60% of the employees are men.

Then the 40% left must be women.

4 of them are selected.

a)  What is the random variable we can consider here?

A random variable is a variable that can have different outcomes or values, in other words, it is a stochastic variable.

We have a selection of 4 employees at random, then we can define the variable X, that represents (for each employee) the possibility of being man or woman.

b) Probability of 3 men and 1 woman.

Suppose that the selection is in the order:

man-man-man-woman.

We have:

0.6 tree times.

0.4 one time.

P = 0.6^3*0.4

But this is for the case where the woman is in the last selection, it can be in the first, second and third, then we have 4 permutations, the actual probability is:

P = 4*( 0.6^3*0.4) = 0.3456.

c) If now we have tat 75% are men, then 25% are women.

Now we can do the same as before, but now the probability for a man is 0.75 and for a woman is 0.25, then the previous equation is now:

P = 4*(0.75^3*0.25) = 0.421875

(a) The random variable will be "Men percentage".

(b) The probability of finding 3 men and one woman be "0.3456".

(c) The probability be "0.4219".

(a) A random variable represents a variable which might have several occurrences as well as quantities; it is indeed a stochastic quantity.

If we choose four workers at random, users may create the variable X, which reflects the potential of someone being a male or even a woman.

(b) The probability be:

→ P(3 men and women) = [tex]4C_3[/tex] (0.6)³ (1 - 0.6)¹

                                       = 0.3456

(c) The probability be:

→ P(3 men and women) = [tex]4C_3[/tex] (0.75)³ (1 - 0.75)¹

                                       = 0.4219

Thus the response above is correct.

Answer:

x = 5

Step-by-step explanation:

Step 1: Write equation

-(1 + 7x) - 6(-7 - x) = 36

Step 2: Solve for x

Step 3: Check

Plug in x to verify it's a solution.

-(1 + 7(5)) - 6(-7 - 5) = 36

-(1 + 35) - 6(-12) = 36

-(36) + 72 = 36

-36 + 72 = 36

36 = 36

Answer:

Answer in explanation

Step-by-step explanation:

The equation of a straight line can be represented in the form;

y = mx + c

where m is slope and c is y-intercept

In this particular case

y = 20x + 5

y is the weekly income, x is the number of lawns mowed

The y-intercept 5 is the amount earned in a week given they no lawn was mowed

In a case where y = 125

125 = 20x + 5

20x = 125-5

20x = 120

x = 120/20

x = 6

Complete Question

Alisa hopes to play beach volleyball in the Olympics someday. She has convinced her parents to allow her

to set up a beach volleyball court in their back yard. A standard beach volleyball court is approximately

26 feet by 52 feet. She figures that she will need the sand to be one foot deep. She goes to the hardware store to shop for sand and sees the following signs on pallets containing bags of sand.

Sand A = 60Ibs = $5

Sand B = 150lbs = $12

Alisa uses her cell phone to search how many pounds of sand is required to fill 1 cubic foot and finds the answer is 100 pounds. Choose one of the brands and compute how much it will cost Alisa to purchase enough sand to fill the court. Identify which brand was chosen as part of your answer.. Answer:

For Sand A should would need:

$11.266.67

Step-by-step explanation:

From the above question, we can assume that: her court is 1 cubic foot and can be filled with 100 pounds of sand

First we find the volume of the box

52ft × 26ft × 1 ft

= 1352 ft³

100Ib = 1 ft³

1352 ft³ × 100 Ib/ft³

= 135200Ibs

Sand A = 60Ibs = $5

Hence, $1 = 60Ibs/5

= 12Ibs

To purchase enough sand using Sand A to fill the court

= 135200Ibs/12lbs

= $11.266.67

Answer:

The point (6,1) lies inside the circle.

Step-by-step explanation:

Equation of a Circle

A circle centered at the point (h,k) and with radius r, can be expressed with the equation:

[tex](x-h)^2+(y-k)^2=r^2[/tex]

The center of the given circle is (0,0) and the radius is [tex]r=\sqrt{38}[/tex], thus the equation of the circle is:

[tex](x-0)^2+(y-0)^2=(\sqrt{38})^2[/tex]

Simplifying:

[tex]x^2+y^2=38[/tex]

Each point (x,y) meeting the condition of the equation lies exactly on its circumference. For example, the point [tex](\sqrt{2},6)[/tex] belongs to the circumference, but the origin (0,0) is inside the circle, and the point (5,5) is outside the circle.

We can tell the difference by evaluating the equation at each point. For the first point [tex](\sqrt{2},6)[/tex], the equation is:

[tex](\sqrt{2})^2+6^2=2+36=38[/tex]

The equation is satisfied.

For the origin (0,0):

[tex]0^2+0^2=0[/tex]

For the point (5,5):

[tex]5^2+5^2=50[/tex]

We can conclude that if the left side is greater than 38, the point is outside the circle, if it's less than 38, the point is inside the circle.

Let's test the point (6,1):

[tex]6^2+1^2=37[/tex]

The point (6,1) lies inside the circle.

Answer:

The formula for D in terms of t is D=0.01875t²

The value of D is 76.8

Step-by-step explanation:

See above for an image

Hope I helped!

After calculating by definition of proportionality, the value of D is 76.8

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

The distance, D, travelled by a particle is directly proportional to the square of the time, t.

So, We can defined as;

⇒ D = k × t²

Where, 'k' is constant of proportion.

Here, When t = 40, D = 30,

⇒ D = k × t²

⇒ 30 = k × 40²

⇒ 30 = k × 1600

⇒ k = 30 / 1600

⇒ k = 3/160

So, When t = 64, the value of D is,

⇒ D = 3/160 × 64²

⇒ D = 76.8
