Find the size of the angle yzx. Give your answer to 3 significant figures
Answers
Answer:
∠ YZX ≈ 19.7°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinZ = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{YZ}[/tex] = [tex]\frac{7.5}{22.3}[/tex] , then
∠ YZX = [tex]sin^{-1}[/tex] ([tex]\frac{7.5}{22.3}[/tex] ) ≈ 19.7° ( to 3 significant figures )

Prove that when a polynomial function p(x) is divided by a first degree polynomial ax + b the remainder is p(-b/a)
Answers
Answer:
r = p(-b/a)
Step-by-step explanation:
Let p(x) = q(x)(ax + b) + r(x) where q(x) is the quotient when p(x) is divided by ax + b and r(x) is the remainder.
Since ax + b is a first degree polynomial, r(x) is one power less than ax + b is is just a constant, r.
So, p(x) = q(x)(ax + b) + r
Now, p(x) = r when q(x)(ax + b) = 0
since q(x) ≠ 0, ax + b = 0 ⇒ ax = -b ⇒ x = -b/a
⇒ p(x) = r when x = -b/a
So, r = p(-b/a)
So, the remainder when a polynomial function p(x) is divided by a first degree polynomial ax + b is p(-b/a)

Samuel spends $8 on lunch. The tax rate is 9%. What is his total cost?
Answers
Answer:
$8.72
Step-by-step explanation:
Since the tax rate is 9% of the lunch cost, the tax for this lunch is .72 dollars since 9% of 8 is 0.72(see math below). You add the 0.72 to 8 and the total cost is $8.72.
8 x (9/100) = tax
8 x 0.09 = 0.72
8+0.72 = $8.72

You roll a 6-sided die.
What is P(5)?
Write your answer as a fraction or whole number.
Answers
Answer:
1/6
Step-by-step explanation:
there is one 5 on the die. therefore the chance of rolling a 5 is 1/6
The required probability P(5) = 1/6.
What is probability?Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
+ Addition operation : Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation : Subtracts right hand operand from left hand operand.
for example 4 -2 = 2
* Multiplication operation : Multiplies values on either side of the operator
For example 4*2 = 8
The die has only one 5 on it.
The number of favorable outcomes = 1
There are the total outcomes as {1, 2, 3, 4, 5, 6}
So the total number of outcomes = 6
Required probability P(5) = 1/6
Hence, the chance of rolling a 5 is 1/6

There is a total of 45 boys and girls in a choir.
The mean age of the 18 boys is 16.2 years.
The mean age of the 27 girls is 16.7 years.
Calculate the mean age of all 45 boys and girls.
Answers
Answer:
16.5 year
Step-by-step explanation:
Using, mean = sum/no. *of observations
Here,
=> 16.2 = (sum of ages of boys)/18
=> 16.2 x 18 = sum of ages of boys
=> 291.6 = sum of ages of boys
Similarly, sum of ages of girls = 27 x 16.7 = 450.9
Mean(total) = (sumof agesof boys + girls)/45
Mean = (291.6 + 450.9)/45 = 16.5
Answer:
The mean age of all 45 boys and girls is 16.5years
Step-by-step explanation:
Since the mean age of the 18 boys is 16.2years,
∴ Sum of their ages = 18 × 16.2
= 291.6years
The mean age of the 27 girls is 16.7years
∴ Sum of their ages = 27 × 16.7
= 450.9years
∴ Mean age of all 45 boys and girls = [tex]\frac{291.6 + 450.9}{45}[/tex] years
= [tex]\frac{742.5}{45}[/tex] years
= 16.5 years
∴ The mean age of all 45 boys and girls is 16.5 years.
