Answer:

y = -x/2 -1/2

Step-by-step explanation:

[tex]x + 2y + 1 = 0\\[/tex]

Write in the y=mx+b form

[tex]2y =-x-1+0\\2y =-x-1[/tex]

Divide both sides by 2

The yearly expense of the in-state college is $16000.

We are given that;

An out-of-state college where the tuition = $7000 per year.

Now,

The yearly expense of the in-state college is:

=5500+12⋅1000

=5500+12000

=17500

By solving;

The yearly expense of the out-of-state college is:

=7000+12⋅750

=7000+9000

=16000

So, on an annual basis, the less expensive choice is the out-of-state​ college.

Therefore, by algebra the answer will be 16000.

Combine like terms

(8 - 3 + 4) + 9t

9 + 9t

9t + 9

Get t by itself

9t + 9 = 0

     -9    -9

9t = -9

Answer:

41/20

Step-by-step explanation:

Simplify the following:

4/5 + 1/2 + 3/4

Hint: | Put the fractions in 4/5 + 1/2 + 3/4 over a common denominator.

Put 4/5 + 1/2 + 3/4 over the common denominator 20. 4/5 + 1/2 + 3/4 = (4×4)/20 + 10/20 + (5×3)/20:

(4×4)/20 + 10/20 + (5×3)/20

Hint: | Multiply 4 and 4 together.

4×4 = 16:

16/20 + 10/20 + (5×3)/20

Hint: | Multiply 5 and 3 together.

5×3 = 15:

16/20 + 10/20 + 15/20

Hint: | Add the fractions over a common denominator to a single fraction.

16/20 + 10/20 + 15/20 = (16 + 10 + 15)/20:

Answer: Statistic.

Step-by-step explanation: Statistic are used to refer to numerical measurement pertaining to a sample. A sample refers to a subset of members chosen from a population, which means a smaller representation of the larger group. Hence, in the scenario above, the population is the entire seniors which makes up the group. While the sample is the subset of seniors drawn from the whole. Hence, statistical measures calculated or derived from the sample is called statistic. Hence, the 25% obtained is a statistic.

The $75 payment that Nelson must make each month after buying the Car is called; A: Premium

Insurance Premium is defined as the amount of money that one will have to pay for an insurance contract. The insurance premium simply represents the income of the insurance company concerned.

Now, the amount of premium paid for different insurance  policies usually differs depending on a number of factors. However, the greater the risks associated with an insurance policy, the higher the premium that will be paid.

Since Nelson must make $75 payment each month, then that is referred to as the Premium.

The equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute

Average speed is defined as the rate of change in distance of a body. Mathematically;

Given the distance of the runner in miles to be;

To express t in terms of the average speed s and distance of 6.2miles, we will substitute the values into the formula;

Substituting D = 6.2miles into the formula;

Cross multiply

Divide both sides by 's'

st/s = 6.2/s

t = 6.2/s

Hence, the equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute

Answer:

the answer would 13

Step-by-step explanation:

Answer:

Step-by-step explanation:

Other trigonometry identities that we have includes cosθ, sinθ, tanθ, secθ, cosecθ

cosecθ = 1/sinθ

Given cotθ=-1/3 and  sinθ<0, this means that θ falls in the 4th quadrant.

cotθ= 1/tanθ = -1/3

tanθ = -3/1

Since tanθ = opposite/adjacent = -3/1

opposite = -3

adjacent = 1

Using pythagoras theorem to get the hypotenuse, hyp² = opp²+adj²

hyp² = (-3)²+1²

hyp = √9+1

hyp = √10

cosθ = adjacent/hypotenuse = 1/√10

sinθ  = opp/hyp = -3/√10

cosecθ = 1/sinθ = 1/(-3/√10)

cosecθ = -√10/3

secθ = 1/cosθ

secθ = 1/(1/√10)

secθ = 1*√10/1

secθ = √10

Answer:

∠EFH = 21°

∠HFG = 62°

∠EFG = 83°

Step-by-step explanation:

The diagram showing the angles has been attached to this response.

From the diagram, it can be deduced that;

Angle EFG = angle EFH + angle HFG

=> ∠EFG = ∠EFH + ∠HFG                -------------------(i)

From the question:

∠EFH = (5x + 1)°                    -------------(ii)

∠HFG = 62°                          -------------(iii)

∠EFG = (18x + 11)°                 -------------(iv)

Substitute these values into equation (i) as follows;

(18x + 11) = (5x + 1) + 62

=> 18x + 11 = 5x + 1 + 62

Collect like terms and solve for x

18x - 5x = 1 + 62 - 11

13x = 52

x = 4

Now, to get each measurement, substitute x = 4 into each of equations (ii) - (iv)

∠EFH = (5x + 1)°

∠EFH = (5(4) + 1)°

∠EFH = (20 + 1)°

∠EFH = 21°

∠HFG = 62°              [Does not depend on x]

∠EFG = (18x + 11)°

∠EFG = (18(4) + 11)°

∠EFG = (72 + 11)°

∠EFG = 83°

Conclusion:

∠EFH = 21°

∠HFG = 62°

∠EFG = 83°

Answer: P = 15/25

Step-by-step explanation:

The set of numbers that we have here is:

{1, 2, 3, 4, 5}

We select independently two numbers of that set (so the numbers can be repeated.

We want to find the probability where the sum of the numbers is less than the product.

if one of the selected numbers is 1, then always the sum will be larger than the product, because:

1*1 = 1 and 1 + 1 = 2

1*2 = 2 and 1 + 2 = 3.

and so on.

if both numbers are 2, the sum is equal to the product:

2*2 = 4 = 2 + 2.

if else, the product will be larger than the product.

The first step now is to calculate the total number of possible combinations of 2 numbers:

For the first number, we have 5 options.

for the second number, we have 5 options.

The total number of combinations is equal to the product of the number of options in each case:

C = 5*5 = 25

Now, the combinations where the product is LESS OR EQUAL than the sum are:

1 and 1

1 and 2

1 and 3

1 and 4

1 and 5.

2 and 1

3 and 1

4 and 1

5 and 1

2 and 2.

10 combinations.

Then the combinations where the product is larger than the sum is:

25 - 10  = 15.

Then the probability that we are looking for is:

P = 15/25

Let me explain the degrees of freedom in statistics.

Step-by-step explanation:

Statistically, degrees of freedom which is denoted as DF is the number of independent values that can vary in an analysis without breaking any constraints. It can also be referred to as the number of independent values that a statistical analysis can estimate.

Degrees of freedom also define the probability distributions for the test statistics of various hypothesis tests.

The degree of freedom has the formula:

DF = N - 1 where N number of random variables

DF = (R - 1) x (C - 1) Where R is the number of data values and C is the number of groups

Answer:6858

Step-by-step explanation:

Answer:

1516 Gallons

Step-by-step explanation:

For this problem, we will simply take the initial amount of water, 1500 gallons, and add the extra water after eight hours.

So if the pool is filling at a rate of 2 gallons per hour, and 8 hours pass by, then the pool will have filled an additional 16 gallons.  (2 * 8 = 16).

Then, we add the initial amount of 1500 gallons to the additional 16 gallons to get the amount of water in the pool after 8 hours.

The total the pool is holding is 1516 gallons after 8 hours.

Q(-6, 1)

Required:

a. PQ

b. Coordinate of the midpoint of PQ

SOLUTION:

a. [tex] PQ = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

Let,

[tex] P(2, 6) = (x_1, y_1) [/tex]

[tex] Q(-6, 1) = (x_2, y_2) [/tex]

[tex] PQ = \sqrt{(-6 - 2)^2 + (1 - 6)^2} [/tex]

[tex] PQ = \sqrt{(-8)^2 + (-5)^2} = \sqrt{64 + 25} [/tex]

[tex] PQ = \sqrt{89} = 3.1 [/tex] (to nearest tenth)

b. Coordinate of the midpoint of PQ

[tex] M(\frac{x_1 + x_2}{2}, \frac{y_1 + y_2}{2}) [/tex]

Let [tex] P(2, 6) = (x_1, y_1) [/tex]

[tex] Q(-6, 1) = (x_2, y_2) [/tex]

Thus:

[tex] M(\frac{2 +(-6)}{2}, \frac{6 + 1}{2}) [/tex]

[tex] M(\frac{-4}{2}, \frac{7}{2}) [/tex]

[tex] M(-2, \frac{7}{2}) [/tex]

The coordinates of the midpoint of PQ are (-2,3.5) and this can be determined by using the midpoint formula.

Given :

Coordinates  --  P(2,6) and Q(-6,1)

The following steps can be used in order to determine the coordinates of the midpoint of PQ:

Step 1 - According, to the given data, the coordinates of point P(2,6) and Q(-6,1).

Step 2 - The formula of midpoint can be used in order to determine the midpoint of PQ.

Step 3 - The midpoint formula is given below:

[tex]\rm x = \dfrac{x_1+x_2}{2}[/tex]

[tex]\rm y = \dfrac{y_1+y_2}{2}[/tex]

Step 4 - Substitute the values of the coordinates in the above formula.

[tex]\rm x = \dfrac{2-6}{2} = -2[/tex]

[tex]\rm y = \dfrac{6+1}{2}=3.5[/tex]

So, the coordinates of the midpoint of PQ are (-2,3.5).
