8×72= 576 fish

48/8= 6 gallons

(a) With a unit rate of 8, repeated (iterated) 72 times, we can simply multiply 8 by 72 to get the net change: 8 × 72 = 576 fish.

(b) For the unit rate (i.e. rate of change per time - minutes in this case) we can simply divide the total water pumped out by the total time it took to perform this. So: 48 ÷ 8 = 6 gallons/min.

Hope I could help you! :)

Given that z is a standard normal random variable, find z for each situation.
cestrela7 [59]
You have to use your standard normal table (or calculator) for these. The area under the curve should be 1, a z-value corresponds to the probability and is area to the left of that z.

a. A simple reverse lookup of 0.9750. z=1.96

b. Total area up to z would be 0.5+0.4750, so reverse look up 0.9750 and find z=1.96

c. A simple reverse lookup. z=0.61

d. Area to the left of z would b 1-0.1314, so lookup 0.8686 and find z=1.12

e. A simple reverse lookup. z=0.44

f. Just invert the area: 1-0.33 = 0.67 and reverse lookup: z=0.44

As an estimation we are told 5 miles is 8 km. <br> Convert 70 miles to km. <br> km
Lena [83]

Answer:  112 km

=====================================================

Work Shown:

(5 miles)/(8 km) = (70 miles)/(x km)

5/8 = 70/x

5*x = 8*70 ... cross multiply

5x = 560

x = 560/5 .... divide both sides by 5

x = 112

According to the given estimation, 70 miles converts to 112 km.

The more accurate conversion is approximately 70 miles = 112.65408 km, so this estimation isn't too far off.

Someone please help me w this standard form question​
svp [43]

Answer:

2.4 × 10⁶

Step-by-step explanation:

Given:

  • \sf x=3.8 \times 10^5
  • \sf y=5.9 \times 10^4

To calculate the value of R, substitute the given values into the given formula:

\begin{aligned}\sf R & = \sf \dfrac{x^2}{y}\\\\ \implies \sf R& = \sf \dfrac{(3.8 \times 10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{3.8^2 \times (10^5)^2}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44 \times 10^{10}}{5.9 \times 10^4}\\\\& = \sf \dfrac{14.44}{5.9} \times \dfrac{10^{10}}{10^4}\\\\& = \sf 2.4474... \times 10^{(10-4)}\\\\& = \sf 2.4474... \times 10^6\\\\\end{aligned}

Therefore, the value of R to 1 decimal place is 2.4 × 10⁶
