4. Compare the function f(x) = –x^2 – 4x + 3 with the function g(x), graphed here. Which function has a greater absolute maximum
inessss [21]

Answer:

f(x) has the greater absolute maximum

Step-by-step explanation:

f(x)=-x^2-4x+3 \\\\f'(x)=-2x-4=-2(x+2)

so f'(x)=0 for x = -2 and f(-2)=-4+8+3=11-4=7

so f(x) has the greater absolute maximum

hope this helps

the number of defectives in 10 different samples of 50 observations each is the following: 5, 1, 1, 2, 3, 3, 1, 4, 2, 3. what is
Law Incorporation [45]

The estimate of the population proportion of defectives is 0.05.

Given that,

There are 10 different samples of 50 observations, that is, total of 500 observations.

To find : The estimate of the population proportion of defectives

And total number of defectives from 500 observations is (5+1+1+2+3+3+1+4+2+3) = 25

Thus, the point estimate for the population proportion defectives will be,

=25/500=0.05

or just obtain the individual proportion of each sample and then take their average to obtain the same result.

Thus, the point estimate for the population proportion defectives will be 0.05

Convert each measure into radians
mars1129 [50]

Answer: -240 = -4π / 3, 60 = π / 3, 270 = 3π / 2, 945 = 21π / 4, -30 = -π / 60, 195 = 13π / 12

Step-by-step explanation:

The formula for converting <em>Degrees </em>into <em>Radians </em>is <em>Degrees </em>* (π / 180) = <em>Radians</em>.

For -240, we have -240 * (π / 180) = -240π / 180 and simplifying gives us -4π / 3

60:  60 * (π / 180) = 60π / 180 = π/3

270:  270 * (π / 180) = 270π / 180 = 3π / 2

945:  945 * (π / 180) = 945π / 180 = 21π / 4

-30:  -30 * (π / 180) = -30π / 180 = π / 60

195:  195 * (π / 180) = 195π / 180 = 13π / 12

draw and label a parallelogram with a base twice as long as the height and an area less than 60 square inches. find the area
liubo4ka [24]
Answer: 5 cm by 10 cm gives an area of 50 cm^2

To do this draw a parallelogram and start by labeling the base as 10 cm. If 10 cm is the base, then the height needs to be 5 cm.

To find the area, multiply the base times height.

This will give you: 5 x 10 = 50 which is less than 60.
