Identify the missing measure

Answer:

The system of equations has one solution. The two equations are intersecting lines.

Step-by-step explanation:

if you want to use the substitution method, you would have to plug in y for 12x+2 in the second equation.

2(12x+2)=x+4

next, you have to distribute

24x+4=x+4

subtract 24x from each side

4=-23x+4

subtract 4 from each side

0=23x

divide each side by 23

x=0

now, plug in 0 to one equation.

y=12(0)+2

y=2

the lines intersect at one point, (0,2)

Answer:

-m^2n^5(1+4mn)

Answer:

The first option.

Step-by-step explanation:

You take the major vertical length and put it into this equation:

2a = 16

a/2 = 16/2

a = 8

You do the same with the minor length.

2b = 10

b/2 = 10/2

b = 5

You then switch the a^2 and the b^2 due to the fact that the veritcal length is longer than the horizontal. Then you use the formula to plug in 8 and 5.

(x - h)^2 / b^2 + (y - k)^2 / a^2 = 1

(x - h)^2 / 5^2 + (y - k)^2 / 8^2 = 1

Answer:

6^2

Step-by-step explanation:

A square has equal sides. The area of a rectangle or square is LxW. Since the length and width are the same it is squared or put to the power (exponent) of 2.

Step-by-step explanation:

10.08 / 3.2 = 3.15

Answer:

a) The value of q is 0.2.

b) E(X) = 1.85.

Step-by-step explanation:

Question a:

The sum of all the probabilities must be 1. So

[tex]0.3 + x + 0.1 + 0.15 + 0.25 = 1[/tex]

[tex]x + 0.8 = 1[/tex]

[tex]x = 0.2[/tex]

The value of q is 0.2.

Question b:

Multiplication of each value of x by its probability. So

[tex]E(X) = 0*0.3 + 1*0.2 + 2*0.1 + 3*0.15 + 4*0.25 = 1.85[/tex]

So the answer is E(X) = 1.85.

Answer:

$15,840

Step-by-step explanation:

10% of 17600 = 1760

17600 - 1760 = 15840

Step-by-step explanation:

Answer:

C. A = 0.5*d1*d2

D. A = bh

Step-by-step explanation:

The area of the rhombus can be found depending on what information is made available to us.

If given the lengths of the two diagonals (d1 and d2) of a rhombus which bisect each other, therefore, the formula for finding the area would be:

A = 0.5*d1*d2

Also, if we are given the height (h) and side (b), the formula to use would be:

A = bh

Answer:

D. (12 x 10) + (5 x 4)

Step-by-step explanation:

If you draw a line separating the big square from the little square,  you have a 12 x 10 large square, and a 5 x 4 smaller square. We know the second dimension of the small square because the large square takes 10ft off of the total length of 4ft.

Calculate both areas separately, then add them together.

The quadratic function represented by the graph as given in the attached image is; Choice C; y = 2x² - 10x + 12.

It follows from the task content that the quadratic function which is represented by the graph be determined.

Since the quadratic function can be modelled as follows; y = a (x - p) (x -q) where; a is a constant, and p and q are the roots of the quadratic function.

Hence, since it follows that the roots are 2 and 3; we have;

y = a (x - 2) (x -3)

Hence, to determine the value of constant, a, we must substitute the values defined by the point given; (1, 4) as follows;

4 = a (1 -2) (1 -3)

4 = a(-1) (-2)

4 = 2a

a = 2.

On this note, the required equation is; y = 2 (x - 2) (x - 3).

Ultimately, the required quadratic function is; Choice C; y = 2x² - 10x + 12.

Answer:

C

Step-by-step explanation:

Sorry if this is wrong.

Answer:

i. A = $25 t + $150

ii. B = $35 t + $100

iii. Number of hours = 5

Step-by-step explanation:

For company A:

A = $25 t + $150

where A is the amount charged and t is the number of hours of landscaping.

For company B:

B = $35 t + $100

where B is the amount charged and t is the number of hours of landscaping.

When the time  is 5 hours, then:

i. A = $25 t + $150

     = $25 (5) + $150

     = $125 + $150

A = $275

ii. B = $35 t + $100

      = $35(5) + $100

      = $175 + $100

B = $275

Therefore, the number of hours that would make the cost of each company to be the same is 5 hours.

Answer:

$133,728 would be in the count after 12 hours.

Step-by-step explanation:

Continuous compounding:

The amount of money, in continuous compounding, after t years, is given by:

[tex]P(t) = P(0)e^{rt}[/tex]

In which P(0) is the initial deposit and r is the interest rate, as a decimal.

Isaac invested $77,000 in an account paying interest rate of 4.6% compounded continuously.

This means that [tex]P(0) = 77000, r = 0.046[/tex]

Assuming no deposits or withdrawals are made, how much money, to the nearest cent, would be the count after 12 years?

This is P(12). So

[tex]P(t) = P(0)e^{rt}[/tex]

[tex]P(12) = 77000e^{0.046*12} = 133728[/tex]

$133,728 would be in the count after 12 hours.

Answer:

Coffee = $2.00

Juice = $1.50

Doughnut = $1.00

Step-by-step explanation:

Given

Let:

[tex]c = coffee\\ j= juice\\ d = doughnut[/tex]

So, we have:

Anna

[tex]2c + j + 2d = 7.50[/tex]

Barry

[tex]c + 3d = 5.00[/tex]

Cathy

[tex]3c + j + 4d = 11.50[/tex]

Required

The price of each

We have:

[tex]2c + j + 2d = 7.50[/tex]

[tex]c + 3d = 5.00[/tex]

[tex]3c + j + 4d = 11.50[/tex]

Make c the subject in: [tex]c + 3d = 5.00[/tex]

[tex]c = 5.00 - 3d[/tex]

Substitute [tex]c = 5.00 - 3d[/tex] in [tex]2c + j + 2d = 7.50[/tex] and [tex]3c + j + 4d = 11.50[/tex]

[tex]2c + j + 2d = 7.50[/tex]

[tex]2[5.00 - 3d] + j + 2d = 7.50[/tex]

[tex]10.00 - 6d+ j + 2d = 7.50[/tex]

Make j the subject

[tex]j = 7.50 - 10.0 +6d - 2d[/tex]

[tex]j = -2.50 +4d[/tex]

[tex]3c + j + 4d = 11.50[/tex]

[tex]3[5.00 - 3d] + j + 4d = 11.50[/tex]

[tex]15.00 - 9d + j + 4d = 11.50[/tex]

Make j the subject

[tex]j = 11.50 - 15.00 + 9d -4d[/tex]

[tex]j = -3.50 + 5d[/tex]

So, we have:

[tex]j = -3.50 + 5d[/tex] and [tex]j = -2.50 +4d[/tex]

Equate both values of  j

[tex]-3.50 + 5d = -2.50 + 4d[/tex]

Collect like terms

[tex]5d - 4d = 3.50 -2.50[/tex]

[tex]d = 1.00[/tex]

Substitute [tex]d = 1.00[/tex] in [tex]j = -3.50 + 5d[/tex]

[tex]j = -3.50 + 5d[/tex]

[tex]j = -3.50 + 5 * 1.00[/tex]

[tex]j = -3.50 + 5.00[/tex]

[tex]j = 1.50[/tex]

To solve for c, we substitute [tex]d = 1.00[/tex] in [tex]c + 3d = 5.00[/tex]

[tex]c + 3 * 1.00 =5.00[/tex]

[tex]c + 3.00 =5.00[/tex]

Solve for c

[tex]c =- 3.00 +5.00[/tex]

[tex]c =2.00[/tex]

Answer:

D. 2.4.

Step-by-step explanation:

S.E. =  std dev / √N

= 24 / √100

= 2.4.

The standard error of the sampling distribution will be 2.4. Then the correct option is D.

The standard deviation of a statistic's sample distribution, or an approximation of that standard deviation, constitutes the statistic's measurement error (SE).

SE = σ / √n

A population has a standard deviation of 24. Then the standard error of the sampling distribution, if the sample size is 100, is calculated as,

SE = σ / √n

SE = 24 / √100

SE = 24 / 10

SE = 2.4

The standard error of the sampling distribution will be 2.4. Then the correct option is D.
