Answer:

r = -9/10

Step-by-step explanation:

Given

7/10 = r - (-8/5)

Required

Solve for x

7/10 = r - (-8/5)

We start by opening the bracket

7/10 = r + (- -8/5)

7/10 = r + (8/5)

7/10 = r + 8/5

Subtract 8/5 from both sides

7/10 - 8/5 = r + 8/5 - 8/5

7/10 - 8/5 = r

Solve the fraction by taking their LCM

(7 - 16)/10 = r

-9/10 = r

Reorder the above

r = -9/10

Hence, the value of r is -9/10

Answer:

Length of AC = 6.67 miles

Step-by-step explanation:

Given:

Angel between B and C = 90°

Angel between A and C = 77°

AB = 1.5 miles

Find:

Length of AC

Computation:

Using trigonometric laws

Cos 77° =  Base / hypotenuses

0.225 = 1.5 / hypotenuses

hypotenuses = 6.67 miles

Length of AC = 6.67 miles

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

"three times r" = 3r

"three times r minus ten" = 3r - 10

"product of 5 and the difference of three times r minus ten"

= 5 (3r - 10)

given that r = 4,

the expression becomes

5 (3r - 10)

= 5 [3(4) - 10]

= 5 [12 - 10]

= 5 (2)

= 10

Answer:

25 students

Step-by-step explanation:

Using the line of best fit, we want to deduce the number of students predicted to be in the marching band given that there are 35 in the concert band.

To deduce this, what we need to do is to go to the point where we have 35 on the concert band axis i.e the x-axis, then trace it upto the line of best fit.

Then from the line of best fit, now trace to the y-axis.

This gives an answer 25.

Question:

The system of equations y = one-fourth x minus 5 and y = negative one-half x minus 3 is shown on the graph below.

Which statement is true about the solution to the system of equations? The x-value is between 2 and 3, and the y-value is between –4 and –5. The x-value is between –4 and –5, and the y-value is between 2 and 3. The x-value is between –2 and –3, and the y-value is between 4 and 5. The x-value is between 4 and 5, and the y-value is between –2 and –3.

Answer:

The solution is

[tex](x, y) = (2,67, -4.33)[/tex]

Therefore, the correct statement is

The x-value is between 2 and 3, and the y-value is between –4 and –5.

Step-by-step explanation:

The given equations are

Equation 1:

[tex]y = \frac{1}{4}x - 5[/tex]

Equation 2:

[tex]y = -\frac{1}{2}x - 3[/tex]

The point of intersection is given by

[tex]\frac{1}{4}x - 5 = -\frac{1}{2}x - 3 \\\\\frac{1}{4}x + \frac{1}{2}x = 5 - 3 \\\\\frac{3}{4}x = 2 \\\\x = \frac{2 (4)}{3} \\\\x = \frac{8}{3} \\\\x = 2.67[/tex]

The corresponding y value is

[tex]y = \frac{1}{4}x - 5 \\\\y = \frac{1}{4}(\frac{8}{3}) - 5 \\\\y = \frac{2}{3} - 5 \\\\y = -\frac{13}{3} \\\\y = -4.33[/tex]

So the solution is

[tex](x, y) = (2,67, -4.33)[/tex]

Therefore, the correct statement is

The x-value is between 2 and 3, and the y-value is between –4 and –5.

Answer:

BF=16

Step-by-step explanation:

To find BF, (I will be calling it x) you need to use the equation

CF/FB=CE/EA Substitute

FB=x

24/x=18/12 cross multiply

18x=288 divide both sides by 18

x=16

FB=16

Answer:

Percent of water in the mixture=88%

Which is 81.07 square inches of the total volume

Step-by-step explanation:

Volume of the flask=πr^2h

π=3.142

radius=diameter/2

=3.71/2

=1.855

height=8.52 inches

Volume of the flask=πr^2h

=3.142*(1.855)^2*8.52

=3.142*3.441025*8.52

=92.115688686

Approximately 92.12 square inches

Flask contains 12% acid solution and the remaining volume is water

Percentage of water =Total percentage - acid solution percentage

=100%-12%

=88%

Percentage of Water =88%

Percentage of the mixture by volume is water=88% of the total volume

=88/100*92.12

Answer:

Hey!

We have been given the price of $26.76. This is the price for 4 pairs of insulated gloves. But, we need to know the unit price.

Unit, means the price of one of those pairs of gloves. To find that we divide.

$26.76 ÷ 4 = 6.69.

But, this is NOT the answer. The answer HAS to have a dollar sign and an explanation.

Our final answer is:

It costs $6.69 for each pair of insulated gloves.

Thank you for your time. Good luck on your assignment!! :D

Answer:

Step-by-step explanation:

Given the points (-8, -8) and (-7, 9), the general form of equation of the line passing through this point is expressed as y-y1 = m(x-x1) where;

m = slope or gradient and (x1, y1) is the point

m = Δy/Δx = y₂-y₁/x₂-x₁

m = 9-(-8)/-7-(-8)

m = 17/1

m = 17

The slope of the line is 17.

The point-slope equation of the line through the point (-7, 9) is expressed as

y-9 = 17(x-(-7))

y-9 = 17(x+7)

Answer:

103 pledges

Step-by-step explanation:

The equation we have here is;

C = 8n + 25

Now we need to find n given that c is $850

simply substitute for the value of c in the question

850 = 8n + 25

850-25 = 8n

825 = 8n

n = 825/8

n = 103.125

But since a pledge cannot be fractional, we can say that n = 103

Answer:

B. 65 degrees

Answer:

b

Step-by-step explanation:

Answer:

(a) 0.635

(b) 0.498

Step-by-step explanation:

(a) The probability distribution is calculated using the cumulative distribution function of the Poisson as follows;

CDF  = [tex]F(x)=e^{-\lambda t}\sum_{i = 0}^{\left | x \right |}\dfrac{\lambda t^{i}}{i!}[/tex]

For x = three we have;

CDF = 0.781

For x = one we have;

CDF = 0.1465

Therefore, the probability that between one and three inclusive = 0.781 - 0.1465 = 0.635

(b) For x = 2 we have;

CDF = 0.4395

For x = one we have;

CDF = 0.9378

Therefore, the probability that between one and three inclusive = 0.9378- 0.4395= 0.498

Answer:

[tex]P(E \cup F)=P(E)+P(F)[/tex].

Step-by-step explanation:

Given the statement

If [tex]P(E)+P(F)=P(E \cup F)+P(E \cap F)[/tex], then E and F are mutually exclusive events.

If two events are mutually exclusive, they have no elements in common. Thus, P(E∩F)=0.

Therefore, the statement is always true as P(E∩F)=0

For mutually exclusive events:

[tex]P(E \cup F)=P(E)+P(F)[/tex].

Answer:

not possible

Step-by-step explanation:

The Law of Detachment is:

If p, then q. p is true. We can then conclude q is true.

For example:

If it rains, the grass gets wet. It is raining. Then the grass is wet.

In the problem in this post, it is not possible to use the Law of Detachment because we have:

If p then q. q is true. We are not told p is true, so we cannot conclude q is true.

Answer: not possible
