Tyshawn is a salesperson who sells computers at an electronics store. He makes a base pay amount each day and then is paid a commission for every computer sale he makes. Let P P represent Tyshawn's total pay on a day on which he sells x x computers. The table below has select values showing the linear relationship between x x and P . P. Determine how many computers Tyshawn would have to sell in order to get paid $225 on a given day. x x P P 3 3 135 135 5 5 165 165 7 7 195

Answers

Answer 1

The required, Tyshawn would need to sell 9 computers to make $225 on a given day.

We can use the values from the table to find the slope of the linear relationship between x and P. We know that the relationship is linear because the table shows a constant increase in P as x increases by the same amount each time.

To find the slope, we can choose any two pairs of values from the table and use the formula:

slope = (change in P) / (change in x)

Using the first and second pairs of values, we get:

slope = (165 - 135) / (5 - 3) = 15

This tells us that Tyshawn's pay increases by $15 for each additional computer he sells.

Now we can use the point-slope form of the equation of a line to find the number of computers he would need to sell to make $225. We know that his pay starts at a base amount and increases by $15 for each computer sold, so the equation is:

P = 15x + b

where b is the base pay amount. We can find b by using one of the pairs of values from the table. Using the first pair, we get:

135 = 15(3) + b

b = 90

So the equation for Tyshawn's pay is:

P = 15x + 90

To find how many computers he needs to sell to make $225, we can substitute P = 225 into the equation and solve for x:

225 = 15x + 90

x = 9

Therefore, Tyshawn would need to sell 9 computers to make $225 on a given day.

The best answer is It is not possible to save any money this month without having a negative actual net income.

This is because saving money means spending less than you earn.

If the actual net income is already zero or positive, there is no room to save without spending more than the income, which would result in a negative actual net income.

3/8 + 2/3 as a mixed number

Answers

To add 3/8 and 2/3, we need to find a common denominator. The least common multiple of 3 and 8 is 24.

We can convert 3/8 to have a denominator of 24 by multiplying the numerator and denominator by 3:

3/8 = (3 x 3) / (8 x 3) = 9/24

We can convert 2/3 to have a denominator of 24 by multiplying the numerator and denominator by 8:

2/3 = (2 x 8) / (3 x 8) = 16/24

Now we can add the two fractions:

9/24 + 16/24 = 25/24

So the sum of the fractions is 25/24.

To convert this improper fraction to a mixed number, we need to divide the numerator by the denominator:

25 ÷ 24 = 1 with a remainder of 1

The whole number is 1 and the remainder is 1 out of 24. So the mixed number is:

1 1/24

Therefore, 3/8 + 2/3 as a mixed number is 1 1/24.

Answers

Our calculation led to a P-value of .516, exceeding the predefined significance level of 0.01 which thereby disproves any evidence indicating individuals whose applications were unsuccessful came from a group whose members had higher mean ages than those who were successful.

How to solve

We will use a two-sample t-test.

Unsuccessful applicants (Group 1):

n1 = 23

Mean1 (x1) = 41.6

Standard deviation1 (s1) = 14.5

Successful applicants (Group 2):

n2 = 25

Mean2 (x2) = 39.7

Standard deviation2 (s2) = 5.4

Claim: μ1 > μ2

Opposite: μ1 ≤ μ2

In order to compare the means of two independent samples, a two-sample t-test is used.

The initial step involves calculating both the pooled variance (Sp^2) and standard error (SE).

To calculate Sp^2, use the formula ((n1 - 1) * s1^2 + (n2 - 1) * s2^2) / (n1 + n2 - 2),

As per our specific data set regarding sample one consisting of 22 values with an average age of 41.6 years old, and sample two having 24 values averaging at 39.7 years old, we derived a pooled variance value of 120.569.

After that, employ the equation SE = √((Sp^2/n1) + (Sp^2/n2)), which yields a value of 3.685 via inputting the aforementioned values.

Using these results enables us to take the difference of the two averages divided by SE in a simplified manner giving a t-score equal to .516.

In light of this test possessing a significance level of 0.01 and utilizing only one tail, a comparison of the calculated t-score to the t-distribution table must occur; using a critical t-value of 2.410 wherein the degrees of freedom are required to be 46.

Our calculation led to a P-value of .516, exceeding the predefined significance level of 0.01 which thereby disproves any evidence indicating individuals whose applications were unsuccessful came from a group whose members had higher mean ages than those who were successful.

The solution is, the value of the variables are x = 40 and, y = 160.

Notice that "x" and "3x+20" are supplementary angles so their sum is 180°

(x) + (3x + 20) = 180

4x + 20 = 180

4x = 160

x = 40

To solve for "y", you have 2 options: either notice that "x" and "y-20" are supplementary angles so their sum is 180° or notice that "3x + 20" and "y - 20" are vertical angles so are equal to each other. I am going to solve using the first option because it is less work.

(x) + (y - 20) = 180°

40 + y - 20 = 180

y + 20 = 180

y = 160

Answer: x=40, y=160

The solution is, the value of the variables are x = 40 and, y = 160.

Find the value of each variable

Factored form of 6x^2+7x-10

Answers

The requried, factored form of 6x²+7x-10 is (6x - 5)(x + 2).

To factor 6x²+7x-10, we need to find two numbers whose product is -60 (the product of the coefficient of x² and the constant term) and whose sum is 7 (the coefficient of x).

Now, we can factor by grouping:

(6x² + 12x) - (5x + 10)

6x(x + 2) - 5(x + 2)

(6x - 5)(x + 2)

Therefore, the factored form of 6x²+7x-10 is (6x - 5)(x + 2).

The measure of the angle m∠ZYX of the trapezoid is equal to 139°

What is a trapezoid?

A trapezoid is a quadrilateral with two parallel sides. The parallel sides are called the bases of the trapezoid, and the other two sides are called the legs. The adjacent angles of the trapezium are supplementary, so their sum is equal to 180°.

3x + 19 + x + 1 = 180°

4x + 20 = 180°

4x = 180 - 20 {collect like terms}

4x = 160

x = 160/4 {divide through by 4}

x = 40

m∠ZYX = 3(40) + 19 = 139°.

WXYZ is a trapezoid. Equation used to solve for x is (3x + 19) + (x + 1) = 180° because the angles m∠XYZ and m∠WXY are adjacent angles.

Petrol price liter increased, increased from Rs 170 of the to Rs 180 per liter. Find what percent price is increased​

Answers

To find the percentage increase in price, we need to calculate the difference between the old price and the new price, divide that by the old price, and then multiply by 100 to get the percentage increase.

The difference between the old price and the new price is:

Rs 180 - Rs 170 = Rs 10

The percentage increase in price is:

(10 / 170) x 100 = 5.88%

Therefore, the price has increased by 5.88%.

log2(x + 4) + log2(3) = log2(8) + log2(2x − 5)

Answers

The solution to the logarithmic equation log₂(x + 4) + log₂(3) = log₂(8) + log₂(2x − 5) is x = 4

Consider the logarithmic equation,

log₂(x + 4) + log₂(3) = log₂(8) + log₂(2x − 5)

We need to solve this equation for x.

Here, the base of logarithm is 2.

Applying product rule of logarithm to log₂(x + 4) + log₂(3) we get,

log₂(x + 4) + log₂(3) = log₂(3(x + 4))

So, our equation becomes,

log₂(3(x + 4)) = log₂(8) + log₂(2x − 5)

log₂(3x + 12) = log₂(2³) + log₂(2x − 5)             .......(2³ = 8)

log₂(3x + 12) = 3log₂(2) + log₂(2x − 5)

log₂(3x + 12) = (3 × 1) + log₂(2x − 5)

log₂(3x + 12) -  log₂(2x − 5) = 3

Applying power identity of logarithm to  -log₂(2x − 5) we get,

-log₂(2x − 5) = 1 / [log₂(2x − 5)]

So, our equation becomes,

log₂(3x + 12) + [1 / log₂(2x − 5)] = 3

Applying product rule of logarithm to  log₂(3x + 12) + [1 / log₂(2x − 5)] we get,  log₂(3x + 12) + [1 / log₂(2x − 5)] =  log₂[(3x + 12) / (2x − 5)]

So, our equation becomes,

log₂[(3x + 12) / (2x − 5)] = 3

Now, exponentiate both sides.

(3x + 12) / (2x - 5) = 2³

(3x + 12) / (2x - 5) = 8

(3x + 12) = 8(2x - 5)

3x + 12 = 16x - 40

13x = 52

x = 4

This is the required value of x.
