Answer:
m ≤ -15
Step-by-step explanation:
You can convert m into positive by multiplying -1 on both sides of the equation. This would also result to a -15.
Note that when an unknown variable changes its sign, the symbol becomes the opposite version of itself.
So,
-m ≥ 15
-m(-1) ≥ 15(-1)
m ≤ -15
Answer:
1.B 2.H 3. A
Step-by-step explanation:
1. First, find out the percentage of people who voted for Mathematika in survey one.
The total amount of people who voted is 14+17+19, which equals 50. 17/50 people voted for Mathematika, 17/50 = 0.34.
To find out how many people out of 300 will vote for Mathematika, multiply the 0.34 by 300. 300 x 0.34 = 102, so 102 people will vote for Mathetika.
2. You use the same logic for number 2. 14+17+19+20+19+11 = 100, so 100 people voted in total. 34 people voted for Infinitus. 34/100 = 0.34. Multiply 0.34 by 750 to get 255 people will vote for Infinitus.
3. The mean = the average. To find the average, add up all of the numbers, then divide that number by the amount of numbers added together.
7+9+11+13+15 = 55
5 numbers were added together so you divide 55 by 5
55/5 = 11. The mean is 11
9+10+11+12+13 = 55
There were 5 numbers added together
55/5 = 11. Both the means were the same
Hey, the answer to your question is 330°
You divide the area of the square by how many sides it has. 6400 ÷ 4 = 1600ft
Answer:
16%
Step-by-step explanation:
Find the z-score.
z = (x − μ) / σ
z = (93 − 85) / 8
z = 1
This means 93 is one standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and +1 standard deviations. So 32% is either less than -1 or greater than +1 standard deviations. Normal curves are symmetrical, so 16% is greater than +1 standard deviations.
