Answer:

Step-by-step explanation:

-we need to change the mix number fractions in improper fractions

-find the common denominator so we can add the fractions

-simplify the fractions whenever possible

-convert it back in a mix number

Obs.

Remember that the order of operations requires us to do multiplication first and then addition.

Given the graph below, which of the following statements is true?

nirvana33 [79]

Answer:

D) The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Step-by-step explanation:

Let's find the ordered pairs.

(-4, 4), (-3, 2), (-2, 0), (-1, 0.5), (0, 1), (1, 1.5), (2, 2), (3, 0)

The graph passed through above points.

In the x-coordinates -3, 2 gives the same output. Therefore, the given function is not one-to-one.

Therefore, the answer D)

The graph does not represent a one-to-one function because the y-values between 0 to 2 are paired with multiple x-values.

Hope you will understand the concept.

Thank you.

4 red balls 4 white balls what is the probability of drawing at least 1 red ball if two balls are drawn

vodomira [7]

The probability of drawing exactly one red ball is given by:
$P(1\ red\ ball)=\frac{4C1\times4C1}{8C2}=\frac{16}{28}$
the probability of drawing two red balls is given by:
$P(2\ red\ balls)=\frac{4C2\times4C0}{8C2}=\frac{6}{28}$
The probability of drawing at least one red ball is:
P(1 red ball) + P(2 red balls) = 16/28 + 6/28 = 11/14.
The answer is $\ \frac{11}{14}$

I need help asap!!!!

kolbaska11 [484]

Answer:

24: x = 31

25: x = 15

Step-by-step explanation:

Remark

24 is supplementary which means that the two angles add to 180o which is on the right hand side of the equation

25 is complementary which means that the two angles add to 90o which is on the left hand side of the equation

Twenty Four

3x + 31 +2x - 6 = 180 Collect the like terms

3x +2x + 31 - 6 = 180 Do the adding and subtracting.

5x + 25 = 180 Subtract 25 from both sides

5x + 25 - 25 = 180 - 25

5x = 155 Divide by 5

x = 155/5

x = 31

Check

3x + 31 = 3*31 + 31

3x + 31 = 93 + 31

3x + 31 = 124

2x - 6 = 2*31 - 6 = 62 - 6 = 56

Total 124 + 56 = 180 as it should.

Twenty Five

Equation

3x+ 4x - 15 = 90

Solution

7x - 15 = 90 Like terms have been collected on the left.

7x = 90 + 15 15 was added to both sides

7x = 105 Divide by 7

x = 15 I'll leave the check to you

Simplify the expression. (16y54y3)12 Enter your answer in the box.

sp2606 [1]

Answer:

Simplify the expression: $(16y^{\frac{5}{4}}y^3)^{\frac{1}{2}}$

Use the exponent power:

$a^n \cdot a^m = a^{n+m}$

$\sqrt[n]{a^n} =a$
$(a^n)^m = a^{nm}$

$(16y^{\frac{5}{4}}y^3)^{\frac{1}{2}}$

Apply the given rules;

$(16y^{\frac{5}{4} +3} )^{\frac{1}{2}}$

Simplify:

$(16y^{\frac{17}{4}} )^{\frac{1}{2}}$

then;

$(16)^{\frac{1}{2}} \cdot (y^{\frac{17}{4}})^{\frac{1}{2}} = 4y^{\frac{17}{8}}$

Therefore, the simplified expression of $(16y^{\frac{5}{4}}y^3)^{\frac{1}{2}}$ is, $4y^{\frac{17}{8}}$
