Step-by-step explanation:

Take the total distance travel (2450) and divide that by the time (43.5) to get the mph. Hope this helps!

Answer:

21.94

Step-by-step explanation:

Convert the percentage to a decimal.

23.7% = 0.237

Divide the number the decimal.

5.2/0.237 = 21.94

The answer is 21.94.

Answer:

6 units above the x-axis

Step-by-step explanation:

The pair (9,6) are a set of coordinates that indicate how far away from the origin (0,0) the point is.

The coordinates are written (x,y) where 'x' is how far to the left or right of the y-axis (vertical) the point is. The 'y' is how far above or below the x-axis (horizontal) the point is.

So in this case, the set of (9,6) means that the point is located at 9 units to the right of the origin and the y-axis and 6 units above the x-axis

Answer:

6 points

Step-by-step explanation:

the y coordinate is 6, so therefore it is 6 higher

Answer:

The correct option is;

Two-tailed test

Step-by-step explanation:

From the interpretation of the question statement, the trader wants to conduct a hypothesis test on the trader's claim that the proportion of stocks that offer dividends is different from 0.14

Given that the difference is hypothesized, then the null hypothesis, H₀ and the alternative hypothesis, H₁ should be written as follows;

H₀: Null hypothesis (no difference, or no change)

H₁: μ ≠ μ₀ which is hypothesizing  difference which is known as a two-tailed test

The confidence level is then selected and the test statistic is calculated

Answer:

The percentage of  volumes that are within 3 standard deviation of the mean is 99.73%.

Step-by-step explanation:

We want to calculate the area under the curve within 3 standard deviations from the mean.

If we use the standard normal distribution, this probability can be calculated as the diference between P(z<3) and P(z<-3).

[tex]P(-3<X<3)=P(z<3)-P(z<-3)\\\\P(-3<X<3)=0.9987-0.0013=0.9973[/tex]

The area under the curve for the standard distribution and for any normal distribution within 3 standard deviation from the mean is 0.9973.

The percentage of  volumes that are within 3 standard deviation of the mean is 99.73%.

Answer:

(a) Bird

(b) 40%

(c) 7%

Step-by-step explanation:

The pie chart is attached below.

Approximate the portion of each type of pet as follows:

Fish ≈ 15%

Bird ≈ 33%

Dog ≈ 17%

Cat ≈ 23%

Other ≈ 7%

None ≈ 5%

(a)

The pet category "Bird" was selected by approximately one-third of

the community.

(b)

The proportion of the community that chose Cat was, 23%.

The proportion of the community that chose Dog was, 17%.

So, the proportion of the community that chose Cat or Dog was:

Cat% + Dog% = 23% + 17%

                       = 40%

(c)

The proportion of the community that chose "Other" was approximately 7%.

Answer:

A. x = -4

Step-by-step explanation:

We are given the equation:

x - 5 = -9

In order to solve for x, we must "undo" the -5 by adding 5 to both sides:

x - 5 + 5 = -9 + 5

x = -4

The answer is thus A.

~ an aesthetics lover

x-5= -9

we need to put everything in the right part to easily calculate it:

x=5 -9 or you can write (-9+5)

then, we have that x= -4

Answer:

Step-by-step explanation

-4(2p - 3) = 28

Do distributive property

-8p + 12 = 28

Subtract 12 from both sides so -8p is isolated

-8p = 16

Divide -8 on both sides to get your answer

p = -2

Answer:

-2

Step-by-step explanation:

-4(2p-3)=28

-8p+12=28

-8p=28-12

-8p=16

p=-2

Answer: A

Step-by-step explanation:

The solution to the graph of inequality given above is the shaded portion or the shaded part of the graph.

Since the point ( -3, -3) and ( 3, -1 ) are on the point line, and the line is a broken line, the inequality means greater than. That means that solution must be greater than those point. They are therefore not part of the solution.

Point ( 5, -5), where x = 5 and y = -5, according to the graph, the shaded portion does not cover y at -5.

Option C is therefore the correct answer which is within the shaded portion. (1, 5)

Answer: Ok for the second one because I don't really get the wording in the first one (thats cuz i SUCK at vocabulary) the answer is 756,100 and a number greater is any number from 756,073-756,149

Step-by-step explanation:

ok so 756072 rounds to 756100 because 72 is closer to 100 than it is to 0

from 50 on, you would round up so to round up to 756100 the smallest possible number is 756050 since the 50 will round up

the highest number is 756149 because from 50 onwards it will round to 756200 instead.

so you can choose any number from 756050-756149

Answer:

y= -3x +6

Step-by-step explanation:

slope-intercept form:

y=mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -3, m= -3.

Susbt. m= -3 into the equation:

y= -3x +c

Since the line passes the point (4, -6),

(4, -6) lies on the line and must therefore satisfy the equation. Thus, susbt. (4, -6) into the equation to find the value of c.

y= -3x +c

when x=4, y= -6,

-6= -3(4) +c

-6= -12 +c

c= 12 -6

c= 6

Hence, the equation of the line is y= -3x +6.

Answer: z=74 , x=6

Step-by-step explanation:

Z = 74

12x+34=180-74

12x=72

x= 6

Answer:

x=6

z=74

Step-by-step explanation:

z and 74 are vertical angles and vertical angles are equal

z = 74

74 and 12x+34 are supplementary angles since they form a line. Supplementary angles  add to 180.  

74+ 12x+34 = 180

Combine like terms

12x+108 = 180

Subtract 108 from each side

12x = 180-108

12x = 72

Divide by 12

12x/12 = 72/12

x =6

Answer:

41°

Step-by-step explanation:

Looking at the attached diagram

A central angle of a circle is always congruent to its intercepted arc.

Therefore, m arc BC = m∠BZC

Again, m∠BAC is one-half m arc BC, as the measure of an inscribed angle is half the measure of its intercepted arc.

This gives us the following results:

= m∠BZC = 82°

= m arc BC = m∠BZC

= m arc BC = 82°

= m∠BAC = 1/2 × 82°

= m∠BAC = 41°

Note that:

∠DCA ≅ ∠BAC because alternate interior angles are congruent.

So m∠DCA = m∠BAC.

Hence, m∠DCA = 41°.

The correct option is C

C)  (2,3,4)

Step-by-step explanation:

Domain can be defined as the set of all possible values of input, for which we can calculate the values of output. The values of input are independent, while the values of output are dependent on the values of input.

In the diagram, we can see that the arrow represents that for a certain number in A, we get a number from B. Which means that A represents the input while B represents the output.

As A is the input, all values of A form the domain of the function, which means that domain in {2,3,4}

Step-by-step explanation:

Answer:

(ax+b) (x+a)

Step-by-step explanation:

Answer:

the lines are perpendicular

Step-by-step explanation:

the first step to this question will be to find the slope intercept form of each of these lines. to do this we will first:

find the slope-

(-3,-1) and (1,-9)

y2-y1 / x2- x1

-9 - (-1)  / 1 - (-3)  (negative - negative = positive)

-8 / 4

therefore the slope is:

-2

we know that slope intercept form is y=mx+b

so.. y= -2x +______

I left the last part blank, because we only have the first half of the equation, now we will substitute the value of x and y into the equation from one of the coordinate points given above.

(-9) = -2(1) + _____

now we can simplify:

-9 = -2

this equation (-9 = -2) is not true, therefore we need to determine what we have to do to -2 to make it equal to -9.

-9 = -2 - 7 is true

therefore the answer is :

y= -2x-7

therefore the slope intercept form is y= -2x - 7

now that you know how to find the slope intercept form, you can find the other slope intercept form, and i'll provide the answer:

the slope intercept form you should find is

y= [tex]\frac{1}{2}[/tex]x + [tex]\frac{7}{2}[/tex]

now when we plot both of these lines we can see that:

the lines are perpendicular, meaning the lines pass through each other.

Answer:

the two lines are perpendicular to one another

Step-by-step explanation:

Find the slopes of the two lines and then compare them.

If the slopes are the same, the lines are parallel.

If the slopes are negative reciprocals, the lines are perpendicular.

If neither of these conditions hold, then the lines are neither parallel nor perpendicular.

(−3,−1) and (1,−9):  As we go from the first point to the second, x (the "run") increases by 4 and y (the "rise") decreases by 8.  Thus, the slope of the line through (−3,−1) and (1,−9) is m = rise / run = -8/4, or m = -2.

(1,4) and (5,6):  As we go from the first to the second, x increeases by 4 and y increases by 2.  Thus, the slope of the line through (1,4) and (5,6) is

m = rise / run = 2/4 = 1/2.

Because 1/2 is the negative reciprocal of -2, we know that the two lines are perpendicular to one another.
