Answer:
Initial amount (a)= 620
Growth factor (b)= 7.8
Step-by-step explanation:
620 is the initial amount and is multiplied by 7.8 x which is the growth factor.
Answer:
The value is a statistic, since it is from a sample.
Step-by-step explanation:
If the value is from a population, it is a parameter.
Otherwise, if the value is from a sample, it is a statistic.
In this question:
In a random sample of U.S. households, it was found that 72% have high-speed Internet.
The value is from a sample, so it is a statistic.
Answer:
x= -5
Step-by-step explanation:
let the number be x.
2x+5= -5 ====> equation
2x= -5-5. (shifted the +5 to the other side)
2x= -10
x= -10/2 ( shifted 2 on the other side as it was multiplying with x)
x= -5
Using proportions, it is found that the least number of teams that will include all of the students is of 10.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 12 + 36 + 9 = 57 students will be divided into teams of no more than 6 students, hence:
57/6 = 9.5.
Rounding up, the least number of teams that will include all of the students is of 10.

There will be 180 mL of water left.
To convert liters to milliliters, multiply by 1000:
0.4(1000) = 400
Each student will use two 5-mL spoons of water; 2(5) = 10 mL each. 10(22) = 220 total mL
400-220 = 180 mL left
