Which algebraic expression is a polynomial with a degree of 2?
4x3 - 2x
10x2 - VX
8x3+3+3
6x2 - 6x + 5

Answer: 18 cm^2

Step-by-step explanation:

There are four equal triangle and a rectangle.

Formula of a rectangle = b * h = 2*3 = 6

Formula of triangle =  [tex]\frac{bh}{2}[/tex] but there four of them so we times them by 4, this leaves us with 2 (b * h) = 2(2*3) = 12

Area of pentagon = area of all triangles + rectangle

Area of pentagon = 12 + 6 = 18

Hope this helps.

Answer:

* Area of Pentagon ⇒ 18 cm^2 *

Step-by-step explanation:

Two of this triangles area are the same provided they are present with similar height and base length. They form a larger triangle such that, for the simplicity, let us start with finding the area of this larger triangle;

Area of Triangle ⇒ 1/2 * base * height ⇒ 1/2 * 6 * 2 ⇒ 6 cm^2

Now there is a similar issue with another two triangles, but they are present to not form a larger triangle. We could imagine that they are next to one another however, and solve for this larger triangle's area;

Area of Triangle ⇒ 1/2 * base * height ⇒ 1/2 * 4 * 3 = 6 cm^2

The last remaining shape is a rectangle, present with dimensions 3 by 2 centimeters such that it's area would be;

Area of Rectangle ⇒ base * height ⇒ 3 * 2 = 6 cm^2

The area of the pentagon is, consecutively;

Area of Pentagon ⇒ 6 + 6 + 6 = 18 cm^2

Answer:

Game:  1/2 lb; Textbook:  2 lb

Step-by-step explanation:

Let the weights of game and textbook be g and t respectively.

Then 6g + 9t = 21 (pounds), and

8g + 9t = 22 (pounds)

Eliminate the variable t by subtracting the first equation from the second.  We get:

2g = 1 (pounds)

Thus, 1 game weights 1/2 lb.

Since 6g + 9t = 21, and g = 1/2 lb,

3 + 9t = 21, or 9t = 18

Then t = 18/9.  1 textbook weighs 2 lb

A. [tex]f(x) = -3(x +2)^2-2[/tex]

Step-by-step explanation:

There is a -3 being multiplied, making the function on the graph narrower from the original. The -3 also makes the function flip over the x-axis, since it's negative. There is also a 2 being added in (x + 2), meaning that it shifts left by 2 units. There is a -2, meaning that the function shifts 2 units down the graph.

Based on the information that applies to this function, this is the only function that represents f(x) on the graph given.

Answer: The answer is dividing the radius in half

Step-by-step explanation: it is a half circle, remember that radius is half the diameter

The radius will be half the refracted base.

Radius is one of the important parts of a circle. It is the distance between the center of the circle to any point on its boundary. In other words, when we connect the center of a circle to any point on its circumference using a straight line, that line segment is the radius of that circle. A circle can have more than one radius because there are infinite points on its circumference. This means that a circle has an infinite number of radii and all the radii of the circle are equidistant from the center of the circle. The size of the circle changes when the length of the radius varies.

The radius of a circle can be found using the three basic radius formulas i.e., when the diameter, the area, or the circumference is known. Let us use these formulas to find the radius of a circle.

As, it is given that the  base of the refraction cup is a half circle.

So, to find the radius of the circle we have to we have to half the base.

This is because the radius is half of the diameter.

Answer:

3.67% probability of randomly seleting 37 cigarettes with a mean of 0.809 g or less.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

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.

In this question, we have that:

[tex]\mu = 0.895, \sigma = 0.292, n = 37, s = \frac{0.292}{\sqrt{37}} = 0.048[/tex]

Find the probability of randomly seleting 37 cigarettes with a mean of 0.809 g or less.

This is the pvalue of Z when X = 0.809.

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{0.809 - 0.895}{0.048}[/tex]

[tex]Z = -1.79[/tex]

[tex]Z = -1.79[/tex] has a pvalue of 0.0367

3.67% probability of randomly seleting 37 cigarettes with a mean of 0.809 g or less.

The correct answer is 1365 ft

Explanation:

The volume refers to the space a body occupies, in the case of the bin made by Lauren this is composed of two rectangular prisms (one in the front and one in the back). Additionally, the volume of each prism can be calculated by multiplying the height, length, and width this means Volume= H x L x W.

According to this, the volume of the front rectangular prism is 735 considering 7ft (H) x 21ft (L) x 5ft (W) = 735 and the volume of the rectangular prism in the back is 630 considering the height of this is 3ft more than the one in the front this means the heigh is 10ft and 10ft (H) x 21ft (L) x 3ft (W) = 630. Finally, it is necessary to add the two volumes to find the total volume, thus 630+ 735 is equivalent to 1365 ft, which is the volume of all the bin.

1365

Answer:

[tex]z=\frac{0.584-0.510 -0.15}{\sqrt{0.551(1-0.551)(\frac{1}{250}+\frac{1}{202})}}=-1.615[/tex]    

The p value would be given by:

[tex]p_v =P(Z<-1.615)= 0.0531[/tex]    

The p value if is compared with a significance of 5% we see that is higher than 0.05 so then at this significance level we have enough evidence to conclude that the true difference in the proportion of males in favor is 15% more than the % of females in favor

Step-by-step explanation:

Information provided

[tex]X_{1}=146[/tex] represent the number of male in favor

[tex]X_{2}=103[/tex] represent the number of female in favor

[tex]n_{1}=250[/tex] sample of males selected

[tex]n_{2}=203[/tex] sample of females selected

[tex]p_{1}=\frac{146}{250}=0.584[/tex] represent the proportion of males in favor

[tex]p_{2}=\frac{103}{202}=0.510[/tex] represent the proportion of females in favor

[tex]\hat p[/tex] represent the pooled estimate of p

z would represent the statistic

[tex]p_v[/tex] represent the value

System of hypothesis

We want to test if the proportion of males in favor is 0.15 point above the proportion of females, the system of hypothesis would be:    

Null hypothesis:[tex]p_{1} - p_{2} \geq 0.15[/tex]    

Alternative hypothesis:[tex]p_{1} - p_{2} <0.15[/tex]    

The statistic is given by:

[tex]z=\frac{p_{1}-p_{2} -0.15}{\sqrt{\hat p (1-\hat p)(\frac{1}{n_{1}}+\frac{1}{n_{2}})}}[/tex]   (1)  

Where [tex]\hat p=\frac{X_{1}+X_{2}}{n_{1}+n_{2}}=\frac{146+103}{250+202}=0.551[/tex]  

Replacing the info given we got:

[tex]z=\frac{0.584-0.510 -0.15}{\sqrt{0.551(1-0.551)(\frac{1}{250}+\frac{1}{202})}}=-1.615[/tex]    

The p value would be given by:

[tex]p_v =P(Z<-1.615)= 0.0531[/tex]    

The p value if is compared with a significance of 5% we see that is higher than 0.05 so then at this significance level we have enough evidence to conclude that the true difference in the proportion of males in favor is 15% more than the % of females in favor

Step-by-step explanation:

in multiplication we have given form of expression

Dividend(D) = Quotient(Q) x Divisor(d) + Remainder(r)

The number which is getting divided is called dividend

divisor is the number which divides the dividend.

quotient is the No. of times a dividend is divisible by divisor.

if dividend is not completely divisible by divisor then leftover after quotient * divisor is remainder.

value of remainder should be always less than divisor.

In  the problem given

Dividend is 75

divisor is 5

so by the given above expression

Dividend(D) = Quotient(Q) * Divisor(d) + Remainder(r) ----> 1

we know that 15*5 = 75

75 = 15*5 + 0

comparing with the  expression 1

we have q = 15

r = 0

Thus, quotient is 15.
