Jacob does the long jump for his track team. On his first jump, he jumped 7

USPshnik [31]

Answer: Jacob's second jump was 6 1/3 feet

Step-by-step explanation:

On his first jump, he jumped 7 2/3

feet. We would convert each mixed fraction to improper fraction

to enable easy addition and subtraction. Converting 7 2/3 feet to improper fraction, it becomes 23/3 feet.

His second jump was 1 1/3 feet shorter. Converting 1 1/3 feet to improper fraction, it becomes 4/3 feet.

Therefore, the distance that Jacob covered on his second jump would be

23/3 - 4/3 = 19/3 feet

Converting 19/3 feet back to mixed fraction, it becomes

6 1/3 feet

A microchip manufacturer has determined that 6% of the processors they produce are defective. A quality technician performs the

Alborosie

Answer:

The expected value for the number of inspections until a defective unit is found 17.

Step-by-step explanation:

Percentage of defective microchips = 6%

Let the total number of inspection = x

number of defective microchip = 1

As we know

1/x = 6%

1/x = 0.06

x = 1/ 0.06

x = 16.67 inspections

x = 17 ( rounded off to nearest whole number )

17 inspection is done until the defective microchip is found.

Because you are shifting the function to the left by 2 units, you will represent that as:

Because you are shifting the function to the left by 2 units, you will represent that as:
$f(x) = (x+2)^2-7$

Generally, if you are moving to the left, it's seen going in the negative direction, but remember since f(x) is going to the left, it means that you are solving for x. So, solve for x in (x + 2), you get x = -2. Hopefully this makes sense.

The, you are dilating the entire function in which you have to multiply the entire thing. Let's do it:
$f(x) = 3((x+2)^2-7)$

Which is equal to:
$f(x) = 3(x+2)^2 -21$

So, your answer is D. If anything doesn't make sense to you, please tell me, I'd be happy to explain!

Solve. 20/n+10 = 10/n+20 n = -10 n = -20 n = 30 n = -30

kirill115 [55]

Answer:

20/n+10 = 10/n+20 n

multiply both side n,

n (20/n+10) = n(10/n+20 n)

20+10n = 10+20n^2

20+10n -20 = 10+20n^2 -20

10n = 20n^2 -10

10n - 10n = 20n^2 -10 -10n

0 = = 20n^2 -10 -10n

20n^2 -10 -10n = 0

n = 1 or n = -0.5
