Elza [17]3 years ago

Answer:

The slope of the line is 14 pounds per day

Step-by-step explanation:

We are given that The local hiking club went on a 7-day hiking trip to Denali National  Park.

The group started with 98 pounds

We are also given that the decreasing amount of food each day is modeled by a linear  function

On Day 1  amount of food = 98 pounds

Since day 7 was the last day

So, On Day 8 amount of food = 0

So,(x_1,y_1)=(1,98)

(x_2,y_2)=(8,0)

Slope = Constant Rate of change per unit

Slope = \frac{y_2-y_1}{x_2-x_1}=\frac{0-98}{8-1}

So, Slope =\frac{-98}{7}

Slope = - 14

Negative sign shows decreasing amount of food each day

Hence the slope of the line is 14 pounds per day

Troy spends $9.75 on chicken feed
Oxana [17]

Answer:

A

Step-by-step explanation:

Total eggs in lay in one week = 48 * 7 = 336

total eggs sold = 336 - 12 = 324

Total dozen = 324 : 12 = 27

Total profit = 27 * 4 = $108

Profit without chicken feed = 108 - 9.75 = $98.25

The variables x and y vary inversely, and x = 12 when y = 6. Use the inverse variation formula, k = xy, to find y when x = 3.
Allushta [10]

Answer:

  24

Step-by-step explanation:

  xy = k

Filling in given values, we have ...

  12·6 = k = 3·y

  y = 12·6/3 = 24

y is 24 when x is 3.

Help me find Sample variance and standard deviation
AnnZ [28]
First, find the mean. You'll need it to compute the variance.

\bar x=\displaystyle\frac15\sum_{i=1}^5x_i=\dfrac{21+10+6+7+11}5=11

The variance of the sample is then computed with the formula

s^2=\displaystyle\dfrac1{5-1}\sum_{i=1}^5(\bar x-x_i)^2=\dfrac{(21-11)^2+\cdots+(11-11)^2}4=\dfrac{71}2=35.5

The standard deviation is the square root of the variance, so

s=\sqrt{35.5}\approx5.958
