Answer:

Answer Choice A (8, eight)

Step-by-step explanation:

To begin, add all of the marbles together. When finished, the answer should be 20. Because the variable 20 equals 100, you divide 4 by 100. You will get 0.04 as a result. This multiplied by 20 equals 8. Finally, the answer is A.

Answer:

the answer is 3/4

the answer is 3/4

Check the picture below, so that happens when h = 0.

now, notice, 0 is also a solution, which means at 0 seconds the ball was touching the ground, well, it was kicked "from" the ground, so at 0 seconds it was initially on the ground anyway.

Answer:

7a + 2b

Step-by-step explanation:

Just remove the parentheses:

Based on the simple interest amount he could be making, and the rate of investment, Tyrell's additional interest per month is $1,000.

Assuming the additional interest that Tyrell is paying is x, the following formula can be used:

300 = (x × 2.5%) x 12 months

Solving gives:

300 = 0.025x × 12

0.025x = 300/12

x = 25 / 0.025

x = $1,000

Answer:

no solution

Step-by-step explanation:

Given equation:

3(2x + 4) - 8x = -2(x + 1) + 3

Expand the brackets:

⇒ 3(2x) + 3(4) - 8x = -2(x) - 2(1) + 3

⇒ 6x + 12 - 8x = -2x - 2 + 3

Collect like terms:

⇒ 6x - 8x + 12 = -2x - 2 + 3

Combine like terms:

⇒ -2x + 12 = -2x + 1

Subtract 12 from both sides:

⇒ -2x + 12 - 12 = -2x + 1 - 12

⇒ -2x  = -2x - 11

Add 2x to both sides:

⇒ -2x + 2x  = -2x +2x - 11

⇒ 0 = -11

The sides are not equal, therefore there is no solution

Answer:

There are no values of x that make the equation true.

Probability helps us to know the chances of an event occurring. The probability of two cards being black without replacement is 24.5%.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given the standard deck has 26 black cards while the total number of cards is 52. Therefore, the probability of two cards being black without replacement is,

Probability = (Probability of the first card is black) × (Probability of the second card being black)

Probability = (26/52) × (25/51)

Probability = 0.245 = 24.5%

Hence, the probability of two cards being black without replacement is 24.5%.

Answer:

Step-by-step explanation:

My approach was to draw out the probabilities, since we have 3 children, and we are looking for 2 boys and 1 girl, the probabilities can be Boy-Boy-Girl, Boy-Girl-Boy, and Girl-Boy-Boy. So a 2/3 chance if you think about it, your answer 2/3 can't be correct. If we assume that boys and girls are born with equal probability, then the probability to have two girls (and one boy) should be the same as the probability to have two boys and one girl. So you would have two cases with probability 2/3, giving an impossible 4/3 probability for both cases. Also, your list "Boy-Boy-Girl, Boy-Girl-Boy, and Girl-Boy-Boy" seems strange. All of those are 2 boys and 1 girl, so based on that list, you should get a 100 percent chance. But what about Boy-Girl-Girl, or Girl-Girl-Girl? You get 2/3 if you assume that adjacencies in the (ordered) list are important, i.e., "2 boys and a girl" means that the girl was not born between the boys.

Answer

The students participating in other than music or dance = 22

Step by step explanation

Total number of students = 72

No. of students participating in dance = 26 (let them be 'a')

No. of students participating in music = 24 (let them be 'b')

No. of students participating in othe na than dance or music = 'c'

72 = a+b+c

= 26+24+c

= 50 + c

c (no. of students participating in other activities)

= 72 - 50 = 22

Answer:

The function role is +2 for x, and -1 for y.

Step-by-step explanation:

The reason for my answer is because as you can see on the table;

For X, it starts at 0 and counts up by 2. For Y, it starts at 2 and counts back by 1.

Step-by-step explanation:

I assume that one a student is picked for an oral exam, the same student will not be picked again.

the total number of possibilities to pick 14 students out of 18 is C(18, 14) = 18!/(14! × (18-14)!) = 18!/(14! × 4!) =

= 18×17×16×15/(4×3×2) = 18×17×2×5 =

= 3,060

how many of these possibilities contain exactly 8 girls and 6 boys ?

so, we choose 8 out of the 10 girls, and 6 out of the 8 boys.

that means

C(10, 8) × C(8, 6) = 10!/(8! × 2) × 8!/(6! × 2) =

= 10×9/2 × 8×7/2 = 5×9 × 4×7 =

= 45 × 28 = 1,260

so, the probability to have 8 girls and 6 boys in a random selection of 14 students out of 18 is

1260/3060 = 21/51 = 7/17 = 0.411764706... ≈ 0.412

What is the equation of the line parallel to y=-5x-9 and contains the point (-3, -3)?

[tex]\blue{\textsf{\textbf{\underline{\underline{Answer and How to Solve:-}}}}[/tex]

First of all, parallel lines have the exact same slope.

So we know the slope of the line:- -5.

(enter -5, It's the number that belongs in the green box)

How about the y-intercept?

Well, since we're given the slope and a point that the line intersects, we can write the line's equation in point-slope form:-

y-y1=m(x-x1)

y-(-3)=-5(x-(-3)

y+3=-5(x+3)

y+3=-5x-15

y=-5x-18

             - - - -- - - - - - - - - - - - - - -- - - - - - - - - - - - -- - - - - - - - - - - - - - -- - - - -

The equation of line which is parallel to y= -5x - 9 is y=-5x-18.

The general equation of a straight line is y = mx + c, where m is the gradient, and y = c is the value where the line cuts the y-axis.

Given:

y= -5x - 9 passes the point (-3, -3)

As, the slope of parallel lines are

m1 = m2 = -5

Now, if the point (-3, -3) intersects the line then equation in point-slope form is

y-y1=m(x-x1)

y-(-3)=-5(x-(-3)

y+3=-5(x+3)

y+3=-5x-15

y=-5x-18

Hence, the equation of line is y=-5x-18

Answer:

The y-intercept is 6

Step-by-step explanation:

The y-intercept of a function is where the graph of an equation touches or crosses the vertical axis. This is usually the value of y when x = 0.

For this particular function, when x = 0 ⇒

f(0) = 0^2 + 4(0) + 6

= 0 + 0 + 6

= 6

Therefore, the y-intercept of this function is 6

Answer:

6

Step-by-step explanation:

the y-intercept is the last number of the equation

so because 6 is the last number, the y-intercept is 6

Given the following

Substitute

Tn = x = 8(2)^52
x = 8(2)^52

If the polar coordinate of a point is (9, π/5). Then the cartesian coordiante will be (7.28, 5.29).

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

The polar coordimnate is given below.

P(9, π/5)

Then the cartesian coordinate will be

We know that the conversion of the polar coordinate to the cartesian coordinate.

(x, y) = (r cos θ, r sin θ)

Then we have

r = 9

θ = π/5

Then we have

x = 9 cos π/5

x = 7.28

y = 9 sin π/5

y = 5.29

Then the coordinate will be (7.28, 5.29).
