The lengths of nails produced in a factory are normally distributed with a mean of 3.34 centimeters and a standard deviation of

Shtirlitz [24]

Answer:

3.47 and 3.21

Step-by-step explanation:

Let us assume the nails length be X

$X \sim N(3.34,0.07^2)$

Value let separated the top 3% is T and for bottom it would be B

$P(X < T)= 0.97$

Now converting, we get

$P(Z < \frac{T-3.34}{0.07})= 0.97$

Based on the normal standard tables, we get

$P(Z < 1.881)= 0.97$

Now compare these two above equations

$\frac{T-3.34}{0.07} = 1.881 \\\\ T = 1.881 \times 0.07 + 3.34 \\\\ = 3.47$

So for top 3% it is 3.47

Now for bottom we applied the same method as shown above

$P(Z < \frac{B-3.34}{0.07})= 0.03$

Based on the normal standard tables, we get

$P(Z < -1.881)= 0.03$

Now compare these two above equations

$\frac{B-3.34}{0.07} = -1.881$

$= -1.881 \times 0.07 + 3.34 \\\\ = 3.21$

hence, for bottom it would be 3.21

Alan compared the slope of the function y=3x+2 to the slope of the linear function that fits the values in this table. Which cho

Anastaziya [24]

OPTIONS:

*The slope of the graph of the table is 1 more than the slope of the graph of the equation.

*The slope of the graph of the table is 2 more than the slope of the graph of the equation.

*The slope of the graph of the equation is 2 more than the slope of the graph of the table.

*The slope of the graph of the equation is 1 more than the slope of the graph of the table.

Answer:

The slope of the graph of the equation is 1 more than the slope of the graph of the table.

Step-by-step explanation:

The slope in the equation of the function, y = 3x + 2, is identified as 3.

We know this because, the equation for the function was given in the slope-intercept form, y = mx + b, where m represents the slope.

Therefore, the slope of the function is 3.

The slope of the function represented by the table of values can be calculated using any two given pairs on the table.

Using (1, 6) and (3, 10):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_2} = \frac{10 - 6}{3 - 1} = \frac{4}{2} = 2$

Slope of the function represented by the table of values is 2.

Therefore, comparing the slope of both functions, we can conclude that:

✅"The slope of the graph of the equation is 1 more than the slope of the graph of the table."

Is this problem correct?

Strike441 [17]

Answer:

Yes that is correct. B is correct.

Step-by-step explanation:

When you plug 0 in for x, the result is 3.

When you plug 1 in for x, the result becomes 1.

The equation matches up correctly.

f(x) = -2x + 3

A farmer in Iowa owns 450 acres of land. He is going to plant each acre with wheat or corn. Each acre planted with wheat yields

Andrei [34K]

Answer:

each 200 acres.

Step-by-step explanation:

Here we are given 2000 profit for wheat per acre and 3000 profit per acre for corn.

Hence objective function to maximize is

$Z=3000W+2000C$

Where W is wheat cultivated and C, corn cultivated

Constraints are workers and acres

Total workers required = 3W+2C and total fertilizers = 2w+4c

$3W+2C\leq 1000\\2W+4C\leq 1200$

We solve and get corner points as

(W,C) = (333,0) (600,0) (0,500) (0,300)

Intersecting point is

by solving we get

2w = 400 or w =200 and c = 200

Thus feasible points are

(200,200) Or (333,0) or (0,300)

Z for I point = 1000000

Z for II point = 666000

Z for III point =900000

Maximum is when wheat and corn are 200 acres each planted.
