Answer:
B and C
Step-by-step explanation:
We need to find which one of these numbers is a perfect square. We know 7 and 13 can be eliminated since they're prime numbers so they can't be perfect squares. B and C are both perfect squares so that's the answer.
Answer:
∠8 * 4 = ∠7 ----------------(1)
∠8 + ∠7 = 180 ------------(2)
Taking the value of ∠7 from (1) and using it in (2):
<u><em>∠7 = 4 * ∠8</em></u>
<u><em /></u>
∠8 + ∠7 = 180
∠8 + (4 * ∠8) = 180
∠8 + 4∠8 = 180
5∠8 = 180
∠8 = 36° ---------------(3)
Using the value of ∠8 from (3) in (2):
∠8 + ∠7 = 180
36 + ∠7 = 180
∠7 = 144° and ∠8 = 36°
Step-by-step explanation:
if 70% of the orice is 420 then
70x = 100 × 420
70x = 42000
x = 42000/70
x = 600
The answer is y=2x+8 because your original is y=my+b
Answer:
Absenteeism significantly increases cost.
Step-by-step explanation:
We are given the following in the question:
The Sensor Dynamics Corporation did a scientific study on the impact of absenteeism on increased costs.
The correlation between the two was found to be 0.7
Correlation:
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and 0.3 tells about a weak positive linear relationship, values between 0.3 and 0.7 shows a moderate positive correlation and a correlation of 0.7 and 1.0 states a strong positive linear relationship.
Thus, we can say that there is a high positive correlation between absenteeism and cost.
Thus, absenteeism significantly increases cost.
