An equation for the total cars and trucks for dealership A is: x + y = 164.

An equation for the total cars and trucks for dealership B is: 2x + 0.5y = 229.

The number of cars that dealership A sold is: 98 cars.

The number of trucks that dealership B sold is: 66 trucks.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of cars sold and number of trucks sold, and then translate the word problem into an algebraic equation as follows:

Since the first dealership sold a total of 164 cars and trucks, a linear equation to model this situation is given by;

x + y = 164.

Additionally, the second dealership sold twice as many cars and half as many trucks as the first dealership, with a total of 229 cars and trucks;

2x + 0.5y = 229.

By solving the systems of linear equations simultaneously, we have:

2x + 0.5(164 - x) = 229

1.5x + 82 = 229

x = 98 cars.

For the y-value, we have;

2(98) + 0.5y = 229

0.5y = 229 - 196

y = 33/0.5

y = 66 trucks.

AREA OF SQUARE

\((x - 1)(x - 1) = x^2 - 2x + 1\)

AREA OF RECTANGLE

\(x(x - 2) = x^2 - 2x\)

Using this we know that the difference is 1, so B is incorrect. We also know that D and E are correct because we solved for the area. C is also wrong, by the same reasoning. Now, all we need to see is if A is right. Plug in x = 2.

\((2)^2 - 2(2) + 1 \\= 4 - 4 + 1 \\= 1\)

Because the area of the square is a square unit larger than the rectangle, the rectangle would have an area of 0, which is impossible, so A is correct.

If  the weights (in pounds) of the gaskets in a batch are 0.58, 0.63, 0.65, 0.53, and 0.61. The gaskets  that should be thrown out is 0.53  and the inequality is: 0.54 ≤ w ≤ 0.66.

Using this formula to determine the mean

Mean = ∑x/n

Mean = 0.58 + 0.63 + 0.65 + 0.53 + 0.61 /5

Mean = 3/6

Mean = 0.6

Since the mean is 0.6 the gasket that are less than 0.53 and more than 0.66 (0.6±0.06) should be thrown out which in turn means that 0.53 should be thrown out.

Answer:

t=14

v=13

q=12

s=23

w=-4

x=28

Step-by-step explanation:

we know that the universal set =100

so, everything in it must add up to 100

first, from the information given to us,

t= n(A n C)= 14

v=n(B n C)= 13

to find q

we know from our guide that n(A) =40

which means everything inside A will add up to 40

therefore,

q + 7 + 7 + t = 40

and we already know that t = 14

so, that will be;

q + 7 + 7 + 14 = 40

therefore, q = 12

to find s,

we all know that n(B) = 50

which means that everything inside B will be equal to 50

therefore,

s + 7 + 7 + v = 50

and we know that v = 13

therefore,

s + 7 + 7 + 13 = 50

and s will end up to be = 23

to find w,

we know that n(C) = 30

so, everything in C end up to be all equal to 30

therefore,

t + 7 + w + v = 30

from our solution, t = 14, v = 13

so,

14 + 7 + w

q = 19, s = 30, t = 7, v = 6, w = 10, x = 7.

A set is a collection of well defined objects.

According to the given question of Venn diagram given,

n(U) = 100, n(A∩B) = 14, n(A) = 40, n(B∩C) = 13, n(B) = 50, n(A∩C) = 14, n(C) = 30 and n(A∩B∩C) = 7.

t =   n(A∩C) - n(A∩B∩C).

t = 14 - 7

= 7.

q = n(A) - [  n(A∩B) + t ]

q = 40 - ( 14 + 7 )

q = 40 - 21

q = 19.

v = n(B∩C) - n(A∩B∩C)

v = 13 - 7

v = 6.

s =  n(B) - [ n(A∩B) + v ]

s = 50 - ( 14 + 6 )

s = 30.

w =  n(C) - [ n(A∩C) + v ]

w = 30 - ( 14 + 6 )

w = 10.

We know x = n(U) - q - s - w - n(A∩B) - n(B∩C) - n(A∩C) +  n(A∩B∩C).

x = 100 - 19 - 30 - 10 - 14 - 13 - 14 + 7.

The percent increase is 200%

Step-by-step explanation:

Answer:

The appropriate solution is:

(a) 0.1056

(b) 0

(c) 0.9544

Step-by-step explanation:

The given values are:

Mean,

\(\mu = 75\)

Standard deviation,

\(\sigma = 4\)

(a)

⇒  \(P(x>80)=1-(x<80)\)

                     \(=1-P[\frac{x-\mu}{\sigma} <\frac{80-75}{4} ]\)

                     \(=1-P[\frac{x-\mu}{\sigma} <\frac{5}{4} ]\)

                     \(=1-P(z<1.25)\)

By using the table, we get

                     \(=1-0.8944\)

                     \(=0.1056\)

(b)

According to the question, the values are:

\(n\) = 64

\(\mu_\bar{x}\) = 75

Now,

⇒  \(\sigma_\bar{x}\) = \(\frac{\sigma}{\sqrt{n} }\)

         = \(\frac{4}{\sqrt{64} }\)

         = \(\frac{4}{8}\)

         = \(0.5\)

⇒  \(P(\bar {x} >80 ) = 1 - P(\bar x <80 )\)

                      \(=1 - P[\frac{(\bar x-\mu_\bar x)}{\sigma \bar x} < \frac{80-75}{0.5} ]\)

                      \(=1-P(z<10)\)

By using the table, we get

                      \(=1-1\)

                      \(=0\)

(c)

As we know,

⇒ \(\sigma_\bar x\) = \(\frac{\sigma}{\sqrt{n} }\)

        = \(\frac{4}{\sqrt{64} }\)

        = \(\frac{4}{8}\)

        = \(0.5\)

then,

= \(P(74< \bar x <76)\)

= \(P[\frac{74-75}{0.5} < \frac{\bar x-\mu \bar x}{\sigma \bar x} < \frac{76-75}{0.5} ]\)

= \(P(-2<z<2)\)

= \(P(z<2)-P(z<-2)\)

By using the table, we get

The area of the Region bounded by y = √x, y = 2-x², and y = -√2x is $\frac{32}{15}$.

To find the area of the region bounded by y = √x, y = 2-x², and y = -√2x, we need to graph the equations and determine the points of intersection. Then we can integrate to find the area.

Firstly, we'll graph the equations and find the points of intersection:

y = √xy = 2-x²y = -√2xGraph of y = √x, y = 2-x², and y = -√2xWe need to solve for the points of intersection, so we'll set the equations equal to each other and solve for x:√x = 2-x²√x + x² - 2 = 0Let's substitute u = x² + 1:√x + u - 3 = 0√x = 3 - u

(Note: Since we squared both sides, we have to check if the solution is valid.)u = -2x²u + x² + 1 = 0 (substituting back in for u

)Factoring gives us:u = (1, -2)We can then solve for x and y:x = ±1, y = 1y = 2 - 1 = 1, x = 0y = -√2x = -√2, x = 2y = 0, x = 0Graph of y = √x, y = 2-x², and y = -√2x with points of intersection to find the area, we need to integrate.

The area is bounded by the x-values -1 to 2, so we'll integrate with respect to x:$$\int_{-1}^0 (2 - x^2) - \sqrt{x} \ dx + \int_0^1 \sqrt{x} - \sqrt{2x} \ dx$$

We can then simplify and integrate:$$\left[\frac{2x^3}{3} - \frac{2x^{5/2}}{5/2} + \frac{4}{3}x^{3/2}\right]_{-1}^0 + \left[\frac{2x^{3/2}}{3} - \frac{4x^{3/2}}{3}\right]_0^1$$$$= \frac{4}{3} + \frac{4}{3} - \frac{4}{15} + \frac{4}{3} - \frac{4}{3}$$$$= \frac{32}{15}$$

Therefore, the area of the region bounded by y = √x, y = 2-x², and y = -√2x is $\frac{32}{15}$.

There is insufficient evidence to say that the population proportion has decreased from 28%.

"Information available from the question"

In the question:

The significance level, α =.01

The sample size, n = 1122

The number of success, x = 291

What are the null and alternative hypotheses?

Now, According to the question;

Let's know:

Significance Level:

The significance level is the area of the rejection region in the hypothesis test. The larger the significance level, the easier is to reject the null hypothesis. The most common significance level used is 5% but in cases where high precision is required significance level is reduced.

\(H_0\) : p \(\geq\) 0.28

\(H_\alpha\) : p < 0.28

The significance level, α =.01

The sample size, n = 1122

The number of success, x = 291

So,

The sample proportion:

p(cap) = x/ n

          = 291/1122

         =  0.2594

Test Statistics:

z = \(\frac{p_c_a_p - p }{\sqrt{p\frac{(1-p)}{n} } }\)

z = \(\frac{0.2594 - 0.28}{\sqrt{0.28\frac{(1-0.28)}{1122} } }\)

z = -0.0206/0.0003396

z = -0.2591

Decision rule:

Reject the null if,

p- value \(\leq\) \(\alpha\)

We can use a z-distribution table, an online tool, or the following excel command to calculate the p-value using excel.

p - value = P(z <  -0.2591)

              = 0.79635

p - value ≈ 0.79635 > \(\alpha\) = 0.01

The probability is found by dividing the number of spaces with a letter by the total number of places the spinner can land.

Step-by-step explanation:

The formula for calculating the future value of an investment compounded annually is:

FV = P(1 + r)^t

where:

FV = future value of the investment

P = principal or initial investment

r = annual interest rate as a decimal

t = number of years the investment is held

In this problem, the principal is given as $4700, the annual interest rate is given as 5.25%, and the time is measured in years since 2007.

So we can write the function as:

y = 4700(1 + 0.0525)^t

In this function, y represents the future value of the investment (in dollars) and t represents the number of years since 2007.

The above function can be written in the form A or A B , where A and B are constants or variable expressions that have no variables in common.

A = 4700

B = 1 + 0.0525

y = A*B^t

So the exponential function for the problem is:
