Answer:

6x - 3y

Step-by-step explanation:

First find the sum

10x - 2y - 3y

10x - 5y

Now do the subtraction

10x - 5y - (4x - 2y)            Remove the brackets.

10x - 5y - 4x + 2y

10x - 4x = 6x

-5y + 2y = - 3y

Answer

6x - 3y

Answer:

-1/2

Step-by-step explanation:

-1/2 is -0.5

-7/10 is -0.7

-0.5 is closer to 0 which means it is greater than -0.7

Answer:

A = 2(11 + 6x)

Step-by-step explanation:

GCF = Greatest Common Factor (remember example: 12 and 16 gcf = 4 because it is the largest number they have together. 12 = 4 * 3 and 16 = 4*4)

22 and 12's GCF is 2:

22 = 2*11

12 = 2*6

Using the distributive property, we can find out that A is the right answer.

However, let us check the other options:

B does not make sense because 6*5 is 30. 6 only applies to 12

C is not correct because it does not apply to 22 or 12

And D only applies to 12 as well because 4*3 = 12 but 4*6 is 24

A should be the answer so I hope this helps!

Answer:

[tex]B = \fra{3V}{h}[/tex]

Step-by-step explanation:

Given

[tex]V = \frac{Bh}{3}[/tex]

Required

Make B the subject

[tex]V = \frac{Bh}{3}[/tex]

Multiply both sides by 3

[tex]3 * V = \frac{Bh}{3}*3[/tex]

[tex]3V = Bh[/tex]

Divide both sides by h

[tex]\fra{3V}{h} = \frac{Bh}{h}[/tex]

[tex]\fra{3V}{h} = B[/tex]

[tex]B = \fra{3V}{h}[/tex]

Answer:

0.3846 = 38.46% probability that the subcommittee consists of 2 men and 1 woman.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

To solve this question, we need to know the combinations formula and conditional probability.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

What is the probability that the subcommittee consists of 2 men and 1 woman, given that it contains both men and women?

Event A: Contains both men and woman

Event B: Consists of two men and 1 woman.

Probability of containing both men and woman:

Desired outcomes:

2 men(from a set of 6) and 1 woman(from a set of 9), or 1 men(from a set of 6) and 2 women(from a set of 9). So

[tex]D = C_{6,2}*C_{9,1} + C_{6,1}*C_{9,2} = \frac{6!}{2!4!}*\frac{9!}{1!8!} + \frac{6!}{1!5!}*\frac{9!}{2!7!} = 351[/tex]

Total outcomes:

3 people from a set of 6 + 9 = 15. So

[tex]T = \frac{15!}{3!12!} = 455[/tex]

Probability:

[tex]P(A) = \frac{D}{T} = \frac{351}{455} = 0.7714[/tex]

Intersection of events A and B:

Intersection between both men and women, and 2 men and 1 woman, is 2 man and 1 women. So

Desired outcomes:

2 men(from a set of 6) and 1 woman(from a set of 9).

[tex]D = C_{6,2}*C_{9,1} = 135[/tex]

Total outcomes:

3 people from a set of 6 + 9 = 15. So

[tex]T = \frac{15!}{3!12!} = 455[/tex]

Probability:

[tex]P(A \cap B) = \frac{D}{T} = \frac{135}{455} = 0.2967[/tex]

Desired probability:

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.2967}{0.7714} = 0.3846[/tex]

0.3846 = 38.46% probability that the subcommittee consists of 2 men and 1 woman.

5y^2+10y+5x^2

Rearrange terms

Solution

5x^2+5y^2+10y

Answer:

0° to 90°: reference angle = angle ,

90° to 180°: reference angle = 180° - angle ,

180° to 270°: reference angle = angle - 180° ,

270° to 360°: reference angle = 360° - angle .

Step-by-step explanation:

Definition of Reference Angle: Let θ be a non-quadrantal angle in standard position. The reference angle of θ is the acute angle θR that the terminal side of θ makes with the x-axis. If θ is in QI, θR = θ If θ is in QII, θR = 180° – θ or π – θ If θ is in QIII, θR = θ – 180° or θ – πThe reference angle of 240° is 60°. To find the reference angle of a given angle, A, with measure x°, we start by adding or subtracting. You can see that the terminal side of the 135° angle and the x-axis form a 45° angle (this is because the two angles must add up to 180°). This 45° angle, shown in red, is the reference angle for 135°.

Answer:

0.2177 = 21.77% conditional probability that she does, in fact, have the disease

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Test positive

Event B: Has the disease

Probability of a positive test:

90% of 3%(has the disease).

1 - 0.9 = 0.1 = 10% of 97%(does not have the disease). So

[tex]P(A) = 0.90*0.03 + 0.1*0.97 = 0.124[/tex]

Intersection of A and B:

Positive test and has the disease, so 90% of 3%

[tex]P(A \cap B) = 0.9*0.03 = 0.027[/tex]

What is the conditional probability that she does, in fact, have the disease

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.027}{0.124} = 0.2177[/tex]

0.2177 = 21.77% conditional probability that she does, in fact, have the disease

Answer:

in order from left to right : NO, NO, YES, NO, YES, NO

Step-by-step explanation:

here's how you can tell! if any point on the line (or singular point) lines up VERTICALLY with a different point, it automatically is not a true function. thats why a vertical slope is "undefined" because its not a function.

i hope this made sense... have a good day !

- A cylindrical fish tank can hold approximately 502.40

cubic inches of water. If the height of the fish tank is

10 inches, what is the radius of the tank? Use 3.14 for

the answer, 6.86

Answer:

it is 5 units

Step-by-step explanation:

All you have to do for this one is subtract 6-1 which equal 5 units. This only works in this one because is says at the end -2 on both the numbers.

Answer:

Eliminate redundant parentheses

( − 5 ) = 1 − 5 = 1

Divide both sides of the equation by the same term− 5 = 1

-5x/-5 = 1/-5

Simplify

Cancel terms that are in both the numerator and denominator

-5x/-5=1/-5     x=1/-5

Divide the numbers

x=-1/5

Answer:

$312.40

Step-by-step explanation:

First, multiply his salary per hour by the hours he worked. (9.55 x 28 = 267.4)

Then, find 15% of 300. (300 / 0.15 = 45)

Now add the two numbers together!

267.4 + 45 = 312.40

Answer:

Let the no. of students be X.

Boys = 60% of X .

So Boys = (60/100)*X.

So left 40% of students are girls and it is given they are 14.

So total students X= total boys + total girls.

X = (60/100)*X+14.

(40/100)*X = 14.

X = (14*100)/40.

X = 35.

X - (60/100)*X = 14.
