3 0

Answer:

0.136

Step-by-step explanation:

If you have a calculator with statistical functions, this problem is straightforward.

Use the normcdf function as follows:

normcdf(300,350,400,50) = 0.136

This result is the probability that a worker makes between $300 and $350 per week:  0.136

The minimum value of f(x) = x3 – 3x2 – 9x + 2 on the interval [–4, 0] is
garri49 [273]

Answer:

-74

Step-by-step explanation:

Graph the function. See attached picture. Between the interval where -4 > x < 0, the graph rises up to a peak and descends back down when x = 0. This means the minimum value will be where x = -4.

Substitute x = -4 into the equation.

f(-4) = (-4)^3 -3(-4)^2 - 9(-4) + 2

f(-4) = -64 -3(16) +36 + 2

f(-4) = -64 - 48 + 36 + 2

f(-4) = -74

Problem solving with inequalities
anzhelika [568]

Option D:

15c ≤ 200

Solution:

Let c be the number of cases of tea bags.

Cost of each tea bag = 15 gold coins

Total gold coins Mad have = 200

<u>Set up an inequality:</u>

Cost of c tea bags = 15 × c = 15c

Mad can buy tea bags at most 200 gold coins.

(At most 200 means 200 is the greater value)

15 × c ≤ 200

15c ≤ 200

Hence option D is the correct answer.

The line represented by the equation 3x + 5y = 2 has a slope of - Which shows the graph of
Lubov Fominskaja [6]

Answer:

Step-by-step explanation:

Solve the given 3x + 5y = 2 for y.  This will automatically indicate the slope of the line.

Subtracting 3x from both sides of this equation, we get:

5y = -3x = -3x + 2.

Dividing both sides by 5 yields y = (-3/5)x + 2/5.

The slope of the given line is -3/5.  The y-intercept of this line is (0, 2/5).

Next time, please share the answer choicess.  Thank you.
