SOMEONE PLEASE HELP ME QUICK
(THE ONE I CLICKED IS THE WRONG ANSWER)
Someone please give me the answer with an explanation.

Answer:

5 options : 2 correct options

: 3 wrong options

first answer : 2/5

second answer : 1/5-1

: 1/4

p( choosing correct answer)

= 2/5 × 1/4

= 1/10

Answer:

0.10

Step-by-step explanation:

hello,

there are 5 answers and 2 are correct

I choose a first answer - the probability to be a correct one is 2/5

then now, there are 4 left answers and only 1 left is correct

the probability to choose the correct one is 1/4

so in total the probability to choose the 2 correct answers out of 5 is

[tex]\dfrac{2}{5}*\dfrac{1}{4}=\dfrac{1}{10}[/tex]

which is 0.10

hope this helps

Answer:

In the picture attached, the graph is shown.

Step-by-step explanation:

No options are provided, so I made the graph.

The equation V = 4 + 2t, is the equation of a line with slope = 2 and y-intercept = 4.

To make a graph, mark some points is helpful. The next points are included in the graph:

t     V  

0    4 + 2(0) = 4

1     4 + 2(1) = 6

2    4 + 2(2) = 8

3    4 + 2(3) = 10

4    4 + 2(4) = 12

5    4 + 2(5) = 14

6    4 + 2(6) = 16

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation:

Use the compound amount formula:  A = P(1 + r)^t, where r is the annual interest rate as a decimal fraction, P is the initial amount of money, and t is the time in years.  Then:

A = ($240,000)(1 + 0.04)^12      (that's 12 years past 2008)

   = ($240,000)(1.04)^12 = $384,247.73

Growth rate:  4%, or 0.04

Independent variable:  time (t)

Dependent variable:  appreciated value of the house, A

Domain:  [0, 30) (assuming that the house is sold within 30 years)

Range:  [$240,000, infinity)   (the house will never sell for an infinite price)

Answer:

The sum of the digits in the first 25 counting numbers, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, and 25 is 127

Step-by-step explanation:

The question regards the addition of single digits in numbers and asks of the sum of the digits in the first 25 numbers as follows;

1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 1 + 0 + 1 + 1 + 1 + 2 + 1 + 3 + 1 + 4 + 1 + 5 + 1 + 6 + 1 + 7 + 1 + 8 + 1 + 9 + 2 + 0 + 2 + 1 + 2 + 2 + 2 + 3 + 2 + 4  + 2 + 5 = 127

The sum of the digits in the first 25 counting numbers, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, and 25 = 127.

Step-by-step explanation:

There are 6 blocks shaded out of 20.

[tex]6/20=3/10=30\%[/tex]

Answer:

x=6 the angle =88

z=92

Step-by-step explanation:

find x

92+11x+22=180

114+11x=180

11x=180-114

x=66/11

x=6 the angle is 11(6)+22=66+22=88

find z=

z+88=180

z=180-88=92

Answer:

m = -6

Step-by-step explanation:

3m = -18 (Divide both sides by 3)

3m/3 = -18/3

m = -6

Answer:

m=-6

Step-by-step explanation:

3m=-18

Divide by 3 on each side.

3m/3=-18/3

m=-6

Step-by-step explanation:

Answer:

y= -2/5 and y=1

Step-by-step explanation:

Start by transforming the equation to your liking:

[tex]5y^2-2=3y\\5y^2-3y-2=0\\[/tex]

Now we have to factor! To do this we have to find common numbers. Do this by multiplying -2 and 5 to get -10. Now think about which two numbers add multiply to be -10 but also add up to be -3 (I got this number from the middle of the equation). The two numbers you should've got are -5 and 2.

Now substitute those two number in place of the middle term, which is -3y like so:

[tex]5y^2-5y+2y-2 =0[/tex]

Now solve the equation in pieces... find the greatest common factor from [tex](5y^2-5y)[/tex] and the greatest common factor from [tex](2y-2)[/tex] . The two common factors for both of those are 5y and 2. Your equation should now look like this:

[tex]5y(y-1)[/tex] + [tex]2(y-1)[/tex]

The two greatest common factors become into one group and the other equation that they have in common (y-1) is it's own equation:

[tex](5y+2)(y-1)=0[/tex]

Now equal both of the equations to 0 and solve for y to get both of the values of y.

Answer:

6 minutes more

Step-by-step explanation:

Time = Distance ÷ Speed

Time = 30miles ÷ 60mph

Time = 30mins

Time = 30miles ÷ 50mph

Time = 36mins

36mins - 30mins = 6mins difference

Answer: 6 minutes

Step-by-step explanation:

Time = Distance / speed

When speed is 60 mph

Time = 30/60 = 1/2 hour = 30 minutes

When speed is 50 mph

Time = 30/50 = 3/5 hour = 36 minutes

Answer:

d

Step-by-step explanation:

Let m = number of miles.

Each mile costs $2.35, so m miles cost 2.35m.

The flat fee is $2.

The total cost is

2.35m + 2

He can spend no more than $47, so he can spend $47 or less,

2.35m + 2 <= 47

Answer: d

Answer:

x = 4

Step-by-step explanation:

It is stated that f(x) passes through

(-3, 3), (0, 3), (4, 3)

and g(x) passes through

(-4, -3), (0, 0), (4, 3)

Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.

Answer:

d x =4

Answer:

B and D

Step-by-step explanation:

In the picture attached, the question is shown.

The graphical solution for a system of two equations is found at the intersection of the two lines. At point (1, 4) line B intersect line D, therefore this point is the solution of the set of equations B and D.

Answer:

D) 0

Step-by-step explanation:

In a ║gm, opposite sides are parallel and equal.

So,

RS = UT

=> x+5 = 2x+5

=> 2x-x = 5-5

=> 2x = 0

=> x = 0

Answer:

142 km^3

Step-by-step explanation:

A=2(wl+hl+hw)

A=2(7*5+3*5+3*7)

A=142

Answer:

[tex]142km^{2}[/tex]

Step-by-step explanation:

you need to find the area of every side and then add them all together so

you do the equation

[tex]2[(7*5)+(3*5) + (7*3)][/tex]

I multiply everything by 2 because there is 2 of every side

once you solve this you get the answer of [tex]142km^{2}[/tex]

Answer: x = 15

Step-by-step explanation:

First, we will have to acknowledge that Angle M is a complementary angle (that means that it is 90 degrees) meaning that 2x° + 4x° will equal 90 degrees. So, let’s set up this equation.

90 = 2x + 4x

90 = 6x

[tex]\frac{90}{6}[/tex] = [tex]\frac{6x}{6}[/tex]

15 = x

Therefore, the x is 15.

Answer:

The additive inverse of the polynomial  being subtracted is -0.612-8+181

Step-by-step explanation:

Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)

Now the polynomial being subtracted : (0.612 + 8 - 181)

Additive inverse : The number in the set of real numbers that when added to a given number will give zero.

So, Additive inverse of 0.612 = -0.612

Additive inverse of 8 = -8

Additive inverse of -181 = 181

So, The additive inverse of polynomial being subtracted : -0.612-8+181

So, Option B is true

Hence the additive inverse of the polynomial  being subtracted is -0.612-8+181

Answer:

Tangent B = eight-sixths

Step-by-step explanation:

Data

From tangent definition:

tan(β) = opposite/adjacent

where β is some angle, and opposite and adjacent are the opposite and adjacent sides (or legs) to that angle.

In our case, B is the angle, opposite to angle B is side AC, and adjacent to angle B is side AB. Replacing with data:

tan(B) = AC/AB

tan(B) = 8/6

Answer:

B is the correct option here

Answer:

150 m

Step-by-step explanation:

Since we have a dome inscribed in a rectangle, and are given the width of the rectangle, we can,

1. Find the diameter of the circle, which is also 150m

2. Find the length of the rectangle, which is 75m (the length of the rectangle is the same as the radius of the circle)

If we are to find the perimeter of the shaded region, we add the length and half the width of the rectangle. So,

75 + 75 = 150m
