Answer:

y=(x+4)^2 -37

Step-by-step explanation:

y+ ? = x^2 +8x+ ?-21

y+? =x^2+8x +16-21

y+16=x^2+8x+16-21

y+16=(x+4)^2 -21

y=(x+4)^2-21-16

Anestetic [448]

Answer:

3.113, 4.507

Step-by-step explanation:

From the given values:

Mean = 3.81

Standard deviation = 1.74

Therefore

M = √(1.72/18) = 0.4

μ = M ± t(sM)

μ = 3.81 ± 1.74*0.4

μ = 3.81 ± 0.697

Recall that the mean is estimated at 90% confidence level,

Hence,

= 90% CI [3.113, 4.507]

Andrei wants to fill a glass tank with marbles, and then fill the remaining space with water. W(n) models the amount of water An
Troyanec [42]

Answer:

0.05

Step-by-step explanation:

We know that the number of marbles is represented by n.  We also know that as the number of marbles increases, the volume of water W(n) decreases, since 0.05n is subtracted.

Since 0.05n is subtracted from 32, then 32 must be the original amount of water used if there are no marbles.

Since the amount of water decreases by 0.05 times the number of marbles, the volume of each marble must be 0.05.

It takes Jonas 7 1/4 minutes to run the mile. It takes Mario 8 5/12 to run the mile. How much faster is Jonas than Mario?
Elanso [62]
We know that

<span>It takes Jonas ---------> 7 1/4 minutes to run the mile
7 1/4-------> (7*4+1)/4------> 29/4 minutes

</span>It takes Mario ---------> 8 5/12 minutes to run the mile
8 5/12-------> (8*12+5)/12------> 101/12 minutes

multiply  (29/4) by (3/3)-------> 87/12


[101/12]-[87/12]------> 14/12 -------> 7/6 -------> 1 1/6 minutes

the answer is
1 1/6 minutes
