<span>FALSE - The domain is all real numbers
TRUE - downward parabola, max-point vertex (-2, 6) So the range is </span><span>{y|y ≤ 6}.</span><span>
TRUE - increases to vertex over the interval (–∞ , –2).
FALSE - The function only decreases from vertex over the interval (−2, ∞).
TRUE - The function has a positive y-intercept.
-(0)^2 - 4(0) + 2 = 2 </span>
Answer:
26) 5 : 11 (simplify it down by 2)
27) 19 : 17 (can't simplify it down)
28) 25 miles per hour (divide 75 by 3)
29) 15 : 24 (subtract 9 from 24 that would leave the amount of students left)
Answer:
$ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample
Step-by-step explanation:
Here
Z∝ =1.64
Standard Deviation=S= 0.21
Sampling Error= SE= 0.05
As Sampling Error is found by
SE= z * s/√n
√n= z*s/ SE
n= (z* s/ SE)²
We use the above formula to calculate N
N= ( Z * S/SE)²
N= (1.64 * 0.21/0.05)²
N= 28.9296= 28.93
Cost of N number of burgers
= Cost *N
= $1.29 * 28.93= $ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample
The perimeter of the rectangle is 120
Answer:
8
Step-by-step explanation:
2 is 40% of 5, so if we stay within this data, then she will win 40% of the next 20 games she plays. 40% of 20 is 8, so she will win 8 games out of 20
