Answer:
first you have to see the twpo numbers then you have to subtract 132|
132 minus 17 and that will give you the answer
Step-by-step explanation:
1.42·10⁷ tons + 1.07·10⁷ tons = 2.49·10⁷ tons . . . . matches the first choice
_____
The distributive property applies.
1.42·10⁷ tons + 1.07·10⁷ tons = (1.42 + 1.07)·10⁷ tons = 2.49·10⁷ tons
Answer:
sin θ = 0.2426.
Step-by-step explanation:
The cot and cos are both negative in the second quadrant.
cot θ = 1 / tan θ = -4 so tan θ = -1/4.
θ = 165.96 degrees
sin θ = 0.2426.
The method that can be used to randomly choose these 500 people is the use of systematic random sampling.
<h3>What is random sampling?</h3>
Random sampling is defined as the method of sampling in which the whole sampling frame is being considered.
In order the survey a community of people to see whether they are willing to have their taxes increased for one year to fund the construction of the skate park, both the male and female should be considered.
The systematic random sampling will give the both male and female equal opportunity to the chosen.

Answer:
- Cameron is 13 and Avery is 8 years old
Step-by-step explanation:
Let Cameron's age be x and Avery's age be y.
<u>The difference is 5 and the product is 104:</u>
<u>Solve by substitution:</u>
- xy = 104
- y(y + 5) = 104
- y² + 5y - 104 = 0
- y = (- 5 ± √(5² + 4*104))/2 = (- 5 ± √441)/2 = ( - 5 ± 21)/2
<u>Taking the positive root as age can't be negative:</u>
<u>Find x:</u>
