Answer:
The value of x = 38
Step-by-step explanation:
As we know that
The mean of a data set is the sum of the terms divided by the total number of terms.
Using math notation we have:
Mean = (Sum of terms) ÷ (Number of terms)
As
Number of terms = 5Mean = 19Sum of terms = -3 + 10 + 22 + x + 28so mean the equation becomes
Mean = (Sum of terms) ÷ (Number of terms)
19 = (-3+10+22+x+28) ÷ 5
19 × 5 = -3+10+22+x+28
95 = x + 57
x = 95 - 57
= 38
Therefore, the value of x = 38

Find the 18th term of the arithmetic sequence whose common difference is d = 2 and whose first term is a, = 3.
Answer:
The 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]
Step-by-step explanation:
We know that the arithmetic sequence with a common difference 'd' and the first term 'a₁' is defined as
[tex]a_n=a_1+\left(n-1\right)d[/tex]
Given the values
d = 2
a₁ = 3
As we have to determine the 18th term of the arithmetic sequence.
so putting n = 18 in the nth term to determine the 18th term.
[tex]a_n=a_1+\left(n-1\right)d[/tex]
[tex]a_{18}=3+\left(18-1\right)2[/tex]
[tex]=3+17\cdot \:2[/tex]
[tex]=3+34[/tex]
[tex]=37[/tex]
Therefore, the 18th term of the arithmetic sequence will be:
[tex]a_{18}=37[/tex]

Debbie cut a cord into sixths. She used five of the pieces to make necklaces. She used equal lengths of the remaining cord for each of four bracelets. What fraction of the original cord did Debbie use
Answer:
1/24
Step-by-step explanation:
Debbie cut a cord into 6 places and use five pieces to make a necklace.
i.e.
5/6 was used to make a necklace and we have 1/6 remaining cord.
However, the remaining cord was used for each of the four bracelets.
i.e.
(1/6) ÷ 4
(1/6) *(1/4) = 1/24
Thus, the fraction of the original cord that Debbie used to make this bracelets = 1/24
∆GHI is an isosceles triangle with a vertex angle H
If the m∠H=80°, then find the m∠I.
Given :
∆GHI is an isosceles triangle with a vertex angle H.
m∠H=80°
To Find :
The m∠I.
Solution :
Since, H is the vertex angle.
So, m∠I = m∠G = x
We know, by angle sum property of triangle :
m∠I + m∠G + m∠H = 180°
2x + 80° = 180°
x = 50°
Therefore, m∠I = 50° .
Answer:
the answer is actually 75 degrees

Find the binomial distribution for flipping a coin 3 times, where "heads" is a success. P(k successes) = nCk pk(1 – p)n – k P(0 successes) = 3C0(0.5)0(0.5)3
Answer:
0.125, 0.375, 0.375, 0.125
Step-by-step explanation:
For a binomial distribution :
nCk * p^k * (1 – p)^(n – k)
P(0 successes) = 0 head, k = 0
n = 3 = number of flips
P(success) = 0.5
3C0 * 0.5^0 * 0.5^3
1 * 0.5^0 * 0.5^3 = 0.125
P( 1 success) = 1 head, k = 1
n = 3 = number of flips
P(success) = 0.5
3C1 * 0.5^1 * 0.5^2
3 * 0.5^1 * 0.5^2 = 0.375
P(2 successes) = 2 head, k = 2
n = 3 = number of flips
P(success) = 0.5
3C2 * 0.5^2 * 0.5^1
3 * 0.5^2 * 0.5^1 = 0.375
P(3 successes) = 3 head, k = 3
n = 3 = number of flips
P(success) = 0.5
3C3 * 0.5^3 * 0.5^0
1 * 0.5^3 * 0.5^0 = 0.125

0.125, 0.375, 0.375, 0.125

This is how you would determine the equation and solve the problem:
- First, it is important that you find how much each eraser cost. You do know that 66 erasers cost $6.60. So create an equation.
- The equation would be: 66/6.60
which means each eraser was 10 cents each
- Now you can create a equation that would determine the cost of 333 erasers since you know how much each eraser actually cost. The equation would be:
- .10×333=?
To create that equation all you need to do is multiply the price of the erasers (10 cents) by how many erasers you are buying (333).

Allison is making treat bags for Valentine's Day. She uses 7 sheets of stickers
and 3 bags of candy for every 8 friends. If Allison is making 14 treat bags, how
many sheets of stickers will she use? How many bags of candy?
The number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.
What is the ratio?It is defined as the comparison between two quantities that how many times the one number acquires the other number. The ratio can be presented in the fraction form or the sign: between the numbers.
Allison uses 7 sheets of stickers and 3 bags of candy for every 8 friends.
It means the ratio of the sticker to candy bags:
7:3 for 8 friends
[tex]\frac{7}{8} :\frac{3}{8}[/tex] for 1 friend or
0.875:0.375
If she makes 14 treat bags then:
The number of sheets of stickers she will use = 0.875×14 ⇒ 12.25
The number of bags of candy she will use = 0.375×14 ⇒ 5.25
Thus, the number of sheets of stickers is 12.25, and the number of bags of candy is 5.25 she will use.

C. f ( x ) = sqr 3 7x and g ( x ) = ( x /7 )3
D. f ( x ) = x /9 + 1 2 g(x) = 9x – 12
The inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.
What is an inverse function?A function in mathematics set up a relationship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
The inverse function of a function f in mathematics is a function that reverses the operation of f. If and only if f is bijective, then the inverse of f exists, and if it exists.
The inverse of the function is given by,
f(x) = 8x – 3 and g ( x ) = x + 3/8
The inverse of the function is calculated by dividing the function by the coefficient of x and reversing the sign of the function.
f(x) = 8x – 3
Divide the function by 8.
f(x) = ( 8x - 3 ) / 8
Reverse the sign of the function.
f(x) = ( 8x + 3 ) / 8
Simplify the function.
f(x) = ( x + 3 / 8 ).
Therefore, the inverse of the function is f(x) = 8x – 3 and g ( x ) = x + 3/8. The correct option is B.

If a board 8 ¾ ft. long is cut into 7 equal parts, how long is each part?
Answer:
26 5/32 in. or 2 ft
Step-by-step explanation:
Since we are taking into account 1/8in for each saw cut the total length of the 4 pieces of wood will be 3/8in less than the single long piece (3 cuts * 1/8).
Let's first convert the piece of wood to inches:
8 3/4ft = 8.75ft
8.75 ft *(12in./1ft) => 8.75 *12= 105 inches
Now we can subtract the 3/8in that will be lost from making 3 cuts:
105in. - 3/8in. = 104 5/8in.
So the total length of the 4 pieces of wood will be 104 5/8in.
Therefore, each piece will be (104 5/8in)/4 in length.
First let's convert 104 5/8in. to an improper fraction to make it easier to work with:
104 5/8in. = (104*8 + 5)/8in.
=837/8in.
Now we can divide this by 4 to get the length of each piece of wood:
(837/8in.)/4 is the same as (837/8in.)*(1/4)
Multiply numerators together, and multiply the denominators together:
(837/8in.)*(1/4) = 837/32in.
Convert back to a mixed number if needed:
837/32in.= 26 5/32in. or 2ft, 2 5/32in.

Consider w=sqrrt2/2(cos(225°) + isin(225°)) and z = 1(cos(60°) + isin(60°)). What is w+ z expressed in rectangular form?
Answer:
Option (3)
Step-by-step explanation:
w = [tex]\frac{\sqrt{2}}{2}[\text{cos}(225) + i\text{sin}(225)][/tex]
Since, cos(225) = cos(180 + 45)
= -cos(45) [Since, cos(180 + θ) = -cosθ]
= -[tex]\frac{\sqrt{2}}{2}[/tex]
sin(225) = sin(180 + 45)
= -sin(45)
= -[tex]\frac{\sqrt{2}}{2}[/tex]
Therefore, w = [tex]\frac{\sqrt{2}}{2}[-\frac{\sqrt{2}}{2}+i(-\frac{\sqrt{2}}{2})][/tex]
= [tex]-\frac{2}{4}(1+i)[/tex]
= [tex]-\frac{1}{2}(1+i)[/tex]
z = 1[cos(60) + i(sin(60)]
= [tex][\frac{1}{2}+i(\frac{\sqrt{3}}{2})[/tex]
= [tex]\frac{1}{2}(1+i\sqrt{3})[/tex]
Now (w + z) = [tex]-\frac{1}{2}(1+i)+\frac{1}{2}(1+i\sqrt{3})[/tex]
= [tex]-\frac{1}{2}-\frac{i}{2}+\frac{1}{2}+i\frac{\sqrt{3}}{2}[/tex]
= [tex]\frac{(i\sqrt{3}-i)}{2}[/tex]
= [tex]\frac{(\sqrt{3}-1)i}{2}[/tex]
Therefore, Option (3) will be the correct option.
