Answer:
B. x = 8√3 ≈ 13.86; y = 8
Step-by-step explanation:
✔️Find x using trigonometric ratio:
Reference angle = 60°
opposite = x
Hypotenuse = 16
Thus:
Sin(60) = x/16
16*sin(60) = x
16*√3/2 = x
8√2 = x
x = 8√3 ≈ 13.86
✔️Find y using Pythagorean Theorem:
y² = 16² - (8√3)²
y² = 256 - 192 = 64
y = √64
y = 8

For the following exercise, determine the range (possible values) of the random variable, X. A batch of 300 machined parts contains 10 that do not conform to customer requirements. The random variable is the number of parts in a sample of 5 parts that do not conform to customer requirements. Choose the correct answer.
a. The range of X is {0,1,2,3,4,5,6}
b. The range of X is {0,1,2,3,4,5,6}
c. The range of X is {0,1,2,3,4,5,6}
d. The range of X is {0,1,2,3,4,5,6}
e. The range of X is {0,1,2,3,4,5,6}
Answer:
{0,1,2,3,4,5}
Step-by-step explanation:
We are given that
Total number of machine parts=300
Number of defective machine parts=10
Total number of good machine parts=300-10=290
Sample contain parts that do not conform to customer requirement=5
X is a random variable which is the number of parts in a sample of 5 parts that do not conform to customer requirements.
We have to find the correct answer.
The sample contain 5 parts
Therefore, the possible values of random variable X
0,1,2,3,4,5
Hence, the range of X is given by
{0,1,2,3,4,5}
Two functions are defined by these equations: f(x) = 5.1 + 0.8x g(x) = 3.4 + 1.2x Which function has a greater value when x is 3.9? How much greater?
Step-by-step explanation:
Two functions are defined by these equations:
f(x) = 5.1 + 0.8x
g(x) = 3.4 + 1.2x
Put x = 3.9 in both f(x) and g(x).
f(x) = 5.1 + 0.8(3.9)
= 8.22
g(x) = 3.4 + 1.2(3.9)
= 8.08
So, f(x) is greater than g(x).
f(x)-g(x) = 8.22 - 8.08
= 0.14
So, f(x) is 0.14 units more than g(x).

Answer:
Option (D)
Step-by-step explanation:
Given expression is,
x³ × 3 ÷ [tex]\frac{2}{9}[/tex] + 9x - (7 - 6x)
By substituting x = [tex]\frac{2}{3}[/tex],
[tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-6(\frac{2}{3})][/tex]
By using rule PEMDAS,
P - Parenthesis
E - Exponent
M - Multiplication
D - Division
A - Addition
S - Subtraction
[tex]=(\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-[7-4][/tex]
= [tex](\frac{2}{3})^3\times 3 \div \frac{2}{9}+9(\frac{2}{3})-3[/tex]
= [tex]\frac{8}{27}\times 3 \div \frac{2}{9}+6-3[/tex]
= [tex]\frac{8}{9}\div \frac{2}{9}+6-3[/tex]
= [tex]\frac{8}{9}\times \frac{9}{2}+6-3[/tex]
= 4 + 6 - 3
= 7

The perimeter of an equilateral triangle is 114mm.
State the length of one of its sides
Answer:
Since an equilateral triangle has all three side equal then one of its side is 38mm
The length of one of the sides of the triangle is 38 mm.
What is Perimeter?The perimeter of a form is the space surrounding its edge. Find the perimeter of various forms by summing the lengths of their sides.
Given that all of the sides of an equilateral triangle are equal in length, we may calculate the length of a side by dividing the perimeter by the triangle's total number of sides, which is 3.
As a result, the equilateral triangle's one side has the following length:
114 mm / 3 = 38 mm
Therefore, the equilateral triangle's sides are each 38 mm long.

The Browns scored 13 more points than the Saints. The total of
their scores was 47. How many points did each team score?
Answer:
Saints team scores points = 17
Browns team scores point = 30
Step-by-step explanation:
Let Saints team scores points = x
Browns team scores point = y
As given,
The Browns scored 13 more points than the Saints.
⇒ y = x + 13
Now, given
The total of their scores was 47.
⇒ x + y = 47
⇒x + x + 13 = 47
⇒ 2x = 47 - 13
⇒2x = 34
⇒x= [tex]\frac{34}{2}[/tex] = 17
∴ we get
Saints team scores points = x = 17
Browns team scores point = y = x + 13 = 17 + 13 = 30
Answer:
30 , 17
Step-by-step explanation:
browns have x + 13
saints have y
x+13 + x+y = 47
2x = 34
x=17
17 + y = 47
y=30
7. Washcloths were selling for $1.88 each. If 14 1/4 dozen cloths were sold, what was the retail value of the total sales
Answer:
The retail value of the total sales was $311.48
Step-by-step explanation:
14 1/4 dozen cloths were sold
This means that the total number of cloths sold was:
[tex]14*12 + 12*\frac{1}{4} = 168 + 3 = 171[/tex]
Each for $1.88
So the retail value of total sales was.
$1.88*171 = $311.48
The retail value of the total sales was $311.48

Fred went to an arcade to play video games. He paid $2 for every 11 tokens he bought. He spent a total of $16 on tokens. Which equation can be used to determine t, the number of tokens Fred bought?
Answer:
D
Step-by-step explanation:
Since there are two types of values here: tokens and dollars, we will need to use the same value across numerators and denominators in the ratio.
Choice D has 11 tokens over $2 equals to t tokens over $16. In both fractions the numerator is tokens and denominator is dollars.
