The answer to this question is actually just simple arithmetic. At the end of the first round, Katie and Jenny will have 100 points each. In the second round, Katie and Jenny will have 200 points and 300 points respectively. At the third round, Katie and Jenny will both have 400 points. At the fourth round, Katie and Jenny will have 800 and 600 points respectively. So the turn at which Katie will have more points than Jenny is the fourth round since Katie has 800 and Jenny has 600.
10 degrees is in a 90 degree angle
90-10 =80
use sin
sin(80)=9/x
get x alone
x=9/sin(80)
Answer:
2630 g
Step-by-step explanation:
From the given information:
Given that:
mean (μ) = 3750 g
Standard deviation (σ) = 500
Suppose the hospital officials demand special treatment with a percentage of lightest 3% (0.03) for newborn babies;
Then, the weight of birth that differentiates the babies that needed special treatment from those that do not can be computed as follows;
P(Z < z₁) = 0.03
Using the Excel Formula; =NORMSINV(0.03) = -1.88
z₁ = - 1.88
Using the test statistics z₁ formula:
By cross multiply, we have:
-1.88 × 500 = X - 3570
-940 = X - 3570
-X = -3570 + 940
-X = -2630
X = 2630 g
Hence, 2630 g is the required weight of birth that differentiates the babies that needed special treatment from those that do not
Answer:
Answer D
Step-by-step explanation:
For each one simple put one of the x values in the x in the given equation. You will find that 9/3 give you 3, 12/3 give you 4. In other questions follow that rule for each and if the answer is the Y value then you know you are right.
These intercepts<span> are plotted in Figure 3.1 and the line </span>3x<span> + </span>2y<span> = </span>12<span> is drawn through them. Figure 3.2: Adding the graph of </span>y<span> = </span>x<span> + 1. The second equation </span>y<span> = </span>x+ 1 has slope-intercept<span> form </span>y<span> = mx + b. Hence, the slope is m = 1 and the </span>y-intercept<span> is (0, 1).</span>
