Answer:
7.0 m/s
Explanation:
This is conservation of momentum, where the momentum of the bowling ball is conserved into both the bowling ball and the beach ball.
(7.0)(2.0) = (7.0)(1.5) + (0.5)x
0.5x = 3.5
x = 7m/s

The only statement that is not true about Invasive Species is; E. They tend to have low reproductive rates.
What are invasive species?Invasive Species are simply defined as plant or animal species that invade ecosystems.
Now, these invasive species are mostly introduced to ecosystems from another ecosystem and as such immediately they establish themselves, will be out-competing native species for resources.
Invasive species generally have high reproductive capacities and efficient dispersal mechanisms. Thus, option E is the wrong option
The missing options are;
a. They may compete with native species for food.
b. They may prey on native species.
They are generally introduced by human activity.
d. They may be plant or animal species.

Mr. red's first year salary is $40,000 and it increases by $1000 each year. what is the explicit rule for this sequence in simplified form?
If Mr. red's first year salary is $40,000 and it increases by $1000 each year. The explicit rule is: an = 1000n + 39,000.
Explicit rule
First term (a1) =40000
Common difference (d) = 1000
Using this formula to find the explicit rule
an = a1 + (n - 1) ×d
Let plug in the formula
an = 40000 + (n - 1) × 1000
Evaluate
an = 40000 - 1000 + 1000n
an =39,000 + 1000n
Rewrite
an = 1000n + 39,000
Therefore the explicit rule of Mr. Red's salary is: an = 1000n + 39,000.

The moment of inertia about the axis of a solid cylinder is _____ the moment of inertia of a cylindrical shell having the same mass and radius.
The moment of inertia about the axis of a solid cylinder is less than the moment of inertia of a cylindrical shell having the same mass and radius.
How to calculate moment of inertia?Mathematically, the moment of inertia for a solid cylinder is calculated by using this formula:
I = (1/2)mr²
Where:
m is the mass.r is the radius.In conclusion, the moment of inertia about the axis of a solid cylinder would be less than the moment of inertia of a cylindrical shell that has the same mass and radius because the mass of the solid cylinder must be taken near the axis of rotation, which makes it smaller.

A student reads in a newspaper that the soil in his area contains high levels of arsenic. Based on this information, he believes that his fellow high school classmates have this metal present in their bodies. To test his hypothesis, he conducts an investigation of the soil in his school yard to see if it is contaminated with arsenic. He tests seven different areas around the school and finds high levels of arsenic in each. He concludes that the students at the school must have high levels of arsenic in their systems as well. Which of these is the best evaluation of his conclusion?
The best evaluation of his conclusion is it is flawed because he did not test the students to see if their bodies contained metal arsenic.
What is arsenic?Arsenic is an element that is usually found mixed with sulfur and other metals.
Its heavy exposure can cause fatalities and its exposure for a long time can damage the liver, skin, kidney, etc.
In the experiment, he doesn't test students for correct results, so the experiment is flawed.
Thus, the correct option is D, His conclusion is flawed because he did not test the students to see if their bodies contained metal arsenic.

A company is considering a capital investment of $16,000 in new equipment which will improve production and increase cash flows for the next five years at the following amounts: year 1: $8,000; year 2: $6,000; year 3: $5,000; year 4: $6,000; year 5: $5,000. the payback period is years.
Based on the cost of the capital investment in the new equipment and the cash flows for the next five years, the payback period is 2.4 years.
What is the payback period?The payback period can be found by the formula:
= Year before payback + Amount remaining to be paid / Cashflow in year of payback
The year before payback can be inferred to be the Second year because $14,000 would have come in.
The remaining amount is:
= 16,000 - 14,000

Answer:
Explanation:
The experimental probability will be different because the chance of it happening doesn't mean it will always happen (which is why people with a 12% chance of life end up making it). This just means it is more likely to happen.

(b) suppose a simple random sampling process is used to select the sample of 100 women. what is the probability that at least 30 percent of the women in the sample will not meet the age requirement for the internships?
Based on the information given, the probability
of a randomly sampled woman not being
qualified for the internship will be 0.223.
The probability of a randomly sampled woman
not being qualified for the internship will be:
= P(x<20) = P(x=17) + P(x=18) + P(x=19)
= 0.005 + 0.107 + 0.111 = 0.223
Also, the probability that at least 30 percent of
the women in the sample will not meet the age
requirement for the internships will be 0.03216
In conclusion, from the information given,
a woman who does not meet the age

The value of x in the right triangle using the Pythagorean theorem is 15 units
How to determine the value of x in the right triangle?From the right triangle (see attachment), we have the following Pythagoras theorem
x² = 12² + 9²
Evaluate the exponents
x^2 = 144 + 81
Evaluate the sum
x^2= 225
Take the square root of both sides
x = ±15
The value of x cannot be negative.

A patient takes a medication with a half life. initially, there are 11 milligrams of the medication in the patient's system. after 70 minutes there are 7 milligrams. after how many minutes will there be only 3 milligrams remaining in the patient's system? round your answer to the nearest whole number, and do not include units.
Using an exponential function, it is found that there will be only 3 milligrams remaining in the patient's system after 201 minutes.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, initially, there are 11 milligrams on the patient's system, hence A(0) = 11. After 70 minutes there are 7 milligrams, hence A(70) = 7, and this is used to find r.
[tex]A(t) = A(0)(1 - r)^t[/tex]
[tex]7 = 11(1 - r)^{70}[/tex]
[tex](1 - r)^{70} = \frac{7}{11}[/tex]
[tex]\sqrt[70]{(1 - r)^{70}} = \sqrt[70]{\frac{7}{11}}[/tex]
[tex]1 - r = \left(\frac{7}{11}\right)^\frac{1}{70}[/tex]
1 - r = 0.99356387084
r = 1 - 0.99356387084
r = 0.00643612916
Hence the equation for the amount after t minutes is:
[tex]A(t) = 11(0.99356387084)^t[/tex]
In will be of 3 mg when A(t) = 3, hence:
[tex]A(t) = 11(0.99356387084)^t[/tex]
[tex]3 = 11(0.99356387084)^t[/tex]
[tex](0.99356387084)^t = \frac{3}{11}[/tex]
[tex]\log{(0.99356387084)^t} = \log{\left(\frac{3}{11}\right)}[/tex]
[tex]t\log{(0.99356387084)} = \log{\left(\frac{3}{11}\right)}[/tex]
[tex]t = \frac{\log{\left(\frac{3}{11}\right)}}{\log{(0.99356387084)}}[/tex]
t = 201
There will be only 3 milligrams remaining in the patient's system after 201 minutes.

How many 3-inch thick bags of mulch should noemi buy to cover 100 square feet at a depth of 4 inches?
Seventeen, 3-inch thick bags of mulch should be used to cover 100 square feet at a depth of four inches.
What are inches and meters?Inches and meters are the units to measure the length or the depth of the objects.
Given,
The length of the bag of mulch = 3.2 ft
The width of the bag of mulch = 2.5 ft
The thickness of the bag of mulch = 0.25 ft
The volume of the mulch bag is calculated as:
[tex]\begin{aligned} \rm volume &= \rm length \times width \times thickness\\\\&= 3.2 \times 2.5 \times 0.25\\\\&= 2 \;\rm cubic \; feet\end{aligned}[/tex]
Given,
The area to be covered = 100 square feet
The depth of the area = [tex]\dfrac{1}{3}[/tex] feet
The volume of the portion needed to be covered is calculated as:
[tex]\begin{aligned} \rm Volume &= \rm area \times depth\\\\&= 100 \times \dfrac{1}{3}\\\\&= 33 \; \dfrac{1}{3} \;\rm cubic \; feet\end{aligned}[/tex]
