Answer:

52 cm^2

Step-by-step explanation:

1) find the area of the rectangle

A = base x width = 8 x 5 = 40 cm^2

2) find the area of the triangle

A = (base x height)/2 = (8x3)/2 = 12 cm^2

3) find the total area

A = 40 + 12 = 52 cm^2

Answer:

Step-by-step explanation:

Area = 8 x 5 + 4 x 3  x 1/2 x 2

Area = 40 + 12 x 1/2 x 2

Area = 40 + 6 x 2

Area = 40 + 12

Area = 52

Answer:

-28(x + 2) = (y - 1)²

Step-by-step explanation:

..............

The equation (y + 1)² = -12(x - 2) represents the given parabola.

What is a parabola?

A parabola is a U-shaped plane curve. It is assumed to be mirror symmetrical. A parabola is produced by the intersection of a right circular cone and a plane parallel to the cone.

The vertex is at (-2, 1) and the directrix is x = 5.

Therefore, the vertex of the given parabola is at 2nd quadrant.

Again, the directrix is also parallel to the y-axis.

As a result, the parabola will open towards the left.

The general form of a parabola is (y - k)² = 4a(x - h)

Here, h and k are x and y coordinates respectively of the vertex.

Now, the coordinates of the focus are (h + a , k) and the directrix is at x = h − a.

Therefore, h - a = 5 (as, x =5)

⇒ 2 - a = 5

⇒ a = -3

Therefore, the equation of the parabola is (y − k)² = 4a(x − h)

⇒ [y - (-1)]² = 4(- 3)(x - 2)

⇒ (y + 1)² = -12(x - 2)

The equation of the parabola that has a vertex (2 , -1) and a directrix

of x = 5 is (y + 1)² = -12(x - 2)

Answer:

In the account that paid 3% Ramon put $800

In the account that paid 6% Ramon put $1,600

Step-by-step explanation:

Answer:

x+y= 9700 & 0.06x + 0.04y=466

Step-by-step explanation:

let X & Y be each account.  Together, they are $9,700.

So, x+y=9700

thus, account 1 (x) earns 6 %. which converted to decimal is 0.06

account 2 (y) earns 4 % which converted is 0.04

It also said that both accounts were $466, after 1 year.

0.06x+0.04y=466

Answer:

By the Central Limit Theorem, an approximately normal distribution, with mean $6425 and standard deviation $344.35.

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Sample mean was $6,425 with a standard deviation of $3,156

This means that [tex]\mu = 6425, \sigma = 3156[/tex]

Sample of 84:

This means that [tex]n = 84, s = \frac{3156}{\sqrt{84}} = 344.35[/tex]

a. Which distribution should you use for this problem?

By the Central Limit Theorem, an approximately normal distribution, with mean $6425 and standard deviation $344.35.

Answer:

FAIL TO REJECT

NOT ENOUGH

Step-by-step explanation:

Given a Pvalue of 0.32

Decision region :

When Pvalue < α ; Reject the Null and conclude that there is significant or enough evidence to accept the alternative hypothesis.

Otherwise, fail to reject reject the null and conclude that, there is not enough evidence to accept the alternative hypothesis

Therefore, for the scenario above, where Pvalue = 0.32

Possible α values are ; 0.1, 0.05, 0.01

For all α - values listed, the Pvalue is greater than α

Pvalue > α ; Hence, FAIL TO REJECT the Null.

Conclusion :

There is NOT ENOUGH evidence to support the alternative that the proportion of students who have ear infection at one school and the other is different.

Step-by-step explanation:

Part A:

Check conditions for a 2-sample t-interval:

Random sample? √

Is the sample size no more than 10% of the population? √

Are both samples approximately normal? √

Construct the 95% confidence interval:

On a TI-84, click on "Stat", scroll to "Tests", and select "2-SampTInt". Put your data into 2 lists and set C-Level to be 0.95 to represent a 95% confidence level. Make sure the data isn't pooled, and press "Calculate" to obtain your results. You will see that the 95% confidence interval for the difference between the mean scores for the two types of instruction is {-6.042,8.1175}

Part B:

The confidence interval does not contradict the claim because 0 is contained within the 95% confidence interval, so it is quite possible that there is no difference between the mean scores for the two types of instruction.

10x2 + 12x - 15x - 18

10x2 - 3x - 18

The product of the given polynomials is 10x² - 3x - 18

A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

The given polynomials are:

(2x – 3)(5x + 6)

By multiplying the two polynomials, we get

10x² + 12x - 15x - 18

10x²- 3x - 18

Hence, 10x²- 3x - 18 is the product of the given polynomials.

C. 360 Square meters

........

The total area is 360 square meter.

Area is the entire amount of space occupied by a flat (2-D) surface or an object's shape. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a shape on paper is the area that it occupies.

Given:

We get Three Rectangle

First Rectangle:

length = 12 m

width = 16 m

So, Area = 12 x 16 = 192 square meter.

Second Rectangle:

length = 8 m

width = 12 m

So, Area = 8 x 12 = 96 square meter.

Third Rectangle:

length = 12 m

width = 6 m

So, Area = 12 x 6 = 72 square meter.

Thus, the total area = 192 + 96+ 72 = 360 square meter.
