Answer:
90 miles
Step-by-step explanation:
1 1/2 is half of 3 so just multiply 45 by two
The x-intercept represents the points in which the quadratic function passes through the x-axis. The maximum value represents the ordered pair with the highest range(y-value).
Interval increasing: (Negative Infinity-10)
Interval Decreasing: (10-Negative Infinity)
Part B: 8/5
Note: I am assuming the scale factor of the graph is 2.
I'm pretty sure the answer is 6.92 cause when you simplify it you'll get that exact answer
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
Answer:
Yes , those ratios are equivalent, because if you simply 18:8 inti the smpilest form you'll get 9:4.
Step-by-step explanation:
18:8= 18/8
18/8÷2/2=9/4
