Answer:

The probability of selecting both yellow is 5/22.

Step-by-step explanation:

Given the number of yellow marbles = 6

Black marbles = 4

Purple marble = 2

Now find the total number of marbles in the jar.

Thus total marbles = Yellow marbles + Black marbles  + Purples marble

Now insert the values in the above formula.

Total marbles = 6 + 4 + 2

Total marbles = 12

The probability of 2 yellow marble:

[tex]= \frac{6}{12} \times \frac{5}{11} \\= \frac{5}{22}[/tex]

Thus, the probability of selecting both yellow is 5/22.

Answer:

B.) 50.91 kilograms

Step-by-step explanation:

Write an equation that looks like this:

[tex]\frac{kilogram}{pound}= \frac{kilogram}{pound}[/tex]

Insert the information in the appropriate section, with 1 kilogram and 2.2 pounds on the same side:

[tex]\frac{1}{2.2}=\frac{x}{112}[/tex]

Solve for x, which is the number of kilograms for 112 pounds if there is 1 kilogram per 2.2 pounds.

Solve for x. Cross multiply:

[tex]1(112)=2.2(x)\\\\112=2.2x[/tex]

Isolate the variable. Divide both sides by 2.2:

[tex]\frac{112}{2.2}=\frac{2.2x}{2.2}\\\\x= 50.909090...[/tex]

Round to the nearest hundredth (two decimal places to the right):

50.909 → 50.91

If 1 kilogram is equal to 2.2 pounds, then 50.91 kilograms is equal to 112 pounds.

Step-by-step explanation:

-3(4x + 2) = 18

Divide by -3:

-3(4x + 2) / -3 = 18 / -3

4x + 2 = -6

Subtract 2:

4x + 2 - 2 = -6 - 2

4x = -8

Divide by 4:

4x / 4 = -8 / 4

Answer:

-24 - 57i

Step-by-step explanation:

i'm assuming that this is a question about imaginary numbers and that i²= -1

we can expand the binomial by using the FOIL method (see attached)

(6 − 7i)(3 − 6i)

= (6)(3) + (6)(-6i) + (-7i)(3) + (-7i)(-6i)

=18 - 36i - 21i + 42i²   (recall that i²= -1)

= 18 - 57i + 42(-1)

= 18 - 57i - 42

= -24 - 57i

Answer:

See below.

Step-by-step explanation:

For 3, we have:

1, 3, 6, ___, 15, 21, _____, 36, _______

Let's try to determine the pattern. From 1 to 3, we added 2.

From 3 to 6, we added 3.

So, it seems that the fourth term would be to add 4, and then add 5. Let's try it:

6+4=10

10+5=15.

So, it seems we're correct. So, we will add 6, then 7, and then 8, etc. Therefore, our correct sequence would be:

1 (+2), 3 (+3), 6 (+4), 10 (+5), 15 (+6), 21 (+7), 28 (+8), 36 (+9), 45

For 4, we have:

100, _____, 64, ______, 36, 25, _______

Notice that these all are perfect squares. 10 squared is 100, 8 squared is 64, etc. Thus, we can rewrite this as:

10², _____, 8², ______, 6², 5², ______

Therefore, our blanks would be:

10², 9², 8², 7², 6², 5², 4².

Evaluated, this woul be:

100, 81, 64, 49, 36, 25, 16.

And we're done!

Answer:

x=20

Step-by-step explanation:

sum of all the sides is equal to 180degrees

group like terms

solve the question

By definition, 3 side lengths are a triangle if any 2 side lengths add up to be greater than the third.

We can already see that the side lengths 6 and 12 will add up to a value of 18, which is equal to the last side length, meaning that the three values are not a triangle.

[tex]a=6[/tex]

[tex]b=12[/tex]

[tex]c=18[/tex]

[tex]a+b>c[/tex]

[tex]b+c>a[/tex]

[tex]c+a>b[/tex]

[tex]6+12>18[/tex] (Since this is not true, this is not a triangle)

Hope this helps.

Answer:

f(g(4) = -11

Step-by-step explanation:

Whenever we are given a composite function where the output of one of the functions serves as an input for the second one, the first step is to evaluate the numerical output from the first function.

Output from first function: g(x) = [tex]x^{2} + x[/tex]

g(4) will be evaluated by substitution 4 for x in the above equation.

this will give us [tex]g(x)=4^{2}+4 =20[/tex]

Output from the composite function f(g(4)

The next stage is to input our results from the function g(4) into the function

f(x) = 9 - x. The output from g(4) which is 20, will now become our input.

[tex]f(x)-9-(20)= -11[/tex]

Therefore f(g(4) = -11

Area = length x width.

Divide the two total areas by the width to find the lengths:

760/16 = 47.5

1000/16 = 62.5

The interval is:

47.5<= x <= 6.5

The interval for the length of x that you will cover before you need to buy more roof coating will be 47.5 ≤ x ≤ 6.5.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.The space occupied by any two-dimensional figure in a plane is called the area.

Given that you have 20 gallons of roof coating to apply to the roof of a mobile home that is 16 feet wide. Twenty gallons covers 760 to 1000 square feet.

The formula to calculate the area of the

Area = length x width.

Divide the two total areas by the width to find the lengths:

760/16 = 47.5

1000/16 = 62.5

The interval is:

47.5 ≤ x ≤ 6.5

Therefore, the interval will be 47.5 ≤ x ≤ 6.5.
