Answer: She needs to bowl 120 or more on her next game.
Step-by-step explanation:
When a constant force is applied to an object, the acceleration of the object varies inversely with its mass. When a certain constant force acts upon an object
with mass 9 kg, the acceleration of the object is 5 m/s². When the same force acts upon another object, its acceleration Is 3 m/s? What is the mass of this
object?
Answer:
Constant Force F= ?
A= 5m/s²
M=9kg
According to the Question
A
[tex] \alpha [/tex]
1/m
A=F/m
So F=ma
F=5×9
F=45N
we look for m using the formula A=F/m
m=F/A
where A=3
F=45
M=?
So M=45/3
M=15kg

Kelly works in a grocery store stocking shelves. The graph below shows the money Kelly earns stocking shelves.
Write an equation to represent the money Kelly earns in relationship to the hours she works. Let m represent the money she earns, and let h represent the number of hours she works.
Answer: m=1/8h
Step-by-step explanation:
When writing a linear equation, the slope is always rise over run. When it rises (goes up) 1, it runs (goes to the side 8. So the slope is 1/8. There is no y intercept because the line passes through (0, 0). The equation is m= because the amount of money earned equals 1/8h.
Simplify this please.

Step-by-step explanation:
Suppose you have a bag containing 5 white marbles, 8 black marbles, 4 red marbles, and 9 green marbles. You draw a
single marble, record the color, and then place the marble back into the bag. You do this 10 times in total. After the final
time, you count your observations and see that you drew a black marble 3 times. Using what you know about theoretical
probabilities, was this likely to occur? Explain.
Answer:Yes

What is the exponential regression equation for the data set?
yˆ=1.08⋅32.11x
yˆ=(1.08⋅32.11)x
yˆ=32.11⋅0.08x
yˆ=32.11⋅1.08x
Answer:
yˆ=32.11⋅1.08x
Step-by-step explanation:
just took the test
Option: A is the correct answer.
The quadratic regression equation for the data set is:
A. y = 0.056x²+1.278x-0.886
What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
We are given a set of data value as:
x y
3 3.45
5 6.9
6 8.79
8 12.91
10 17.48
12 22.49
15 30.85
On plotting these points on a scatter plot we see that the line that best fits these data points is a parabola i.e. the equation is a equation of a quadratic function.
The equation of the line of best fit is:
y = 0.056x²+1.278x-0.886

Answer:
-9, -5, -4.1, -4
[tex]\\q\leq -4[/tex]
Step-by-step explanation:
I think what you're missing here is that there is a negative sign in front of the q. This means that whatever number you put in for q will be multiplied by negative 1. Positive numbers will become negative, and negative numbers will become positive.
If you substitute 9 for q you will get [tex]-9\geq 4[/tex], which is clearly not true, because -9 is way less than 4.
For writing the equation you divide both sides by -1. When you do this however, you must flip the inequality sign
[tex]-q\geq 4\\q\leq -4[/tex]
the > sign turned into <, and the q and 4 switched signs.
What does it mean to restate using scientific notion
Restating into scientific notation means, making a super big or a super small number, more understandable to read. For example,
5,972,000,000,000,000,000,000,000.0012 is a big number. I don't think you even tried to read that. There is a solution to this problem. This is the exact number but in scientific notation. 5.972 × 10^24. Isn't that easier to read?

What is the total surface area of this cube?
Answer:
54 (also include units squared as the picture isn't clear)
Step-by-step explanation:
3×3=9 (area of square =l×b)
9×6= 54cm² (since a cube has 6 faces)
The length of life of oil-drilling bits depends upon the types of rock and soil that the drill encounters, but it is estimated that the mean length of life is 55 hours. An oil exploration company purchases drill bits that have a length of life that is approximately normally distributed with mean equal to 55 hours and standard deviation equal to 9.1 hours.
What proportion of the company’s drill bits will have to be replaced after more than 90 hours of use?
Answer:
"0.9999" is the correct solution.
Step-by-step explanation:
The given values in the question are:
Mean,
= 55
Standard deviation,
= 9.1
Now,
⇒ [tex]z=\frac{X-mean}{sd}[/tex]
By putting the values, we get
⇒ [tex]=\frac{90-55}{9.1}[/tex]
⇒ [tex]=\frac{35}{9.1}[/tex]
⇒ [tex]=3.8461[/tex]
hence,
[tex]P(X<90)[/tex]
= [tex]P(Z<3.8461)[/tex]
= [tex]NORMSDIST(3.8461)[/tex]
then the value will be:
= [tex]0.9999[/tex]

4. Thirty students from the Netherlands set up a record of 1,500,000 dominoes. Of these, 1,138,101 were toppled by one push. Which is a more reasonable estimate for how many dominoes remained standing after that push: 350,000 or 400,000?
Answer:
361,899
hope this helps
Answer:
350,000
Step-by-step explanation:
1,500,000 - 1,138, 101 = 361,899
361,899 - 350,000 = 11,899
400,000 - 361,899 = 38,101
11,899 is less than 38,101
So, 350,000 is the answer.
The ages of job applicants for a security guard position are uniformly distributed between 25 and 65. Could a 25-year-old job applicant be two standard deviations below the mean (or more than two standard deviations)?
Answer:
No, a 25-year-old job applicant cannot be two standard deviations below the mean
Step-by-step explanation:
There are two frequencies 25 and 65
Mean of the two frequencies = 25+65/2 = 45
Standard deviation =
[tex]\frac{65-25}{\sqrt{12} } \\= 11.55[/tex]
Mean - 2 x standard deviation [tex]= 45 - 2 * 11.55 = 21.9[/tex]
[tex]21.9 < 25[/tex]
Thus, a 25-year-old job applicant cannot be two standard deviations below the mean

Suppose a city with population 900,000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 19 years
Answer:
Future population in 19 years = 3,254,580 people (Approx.)
Step-by-step explanation:
Given:
Current population of city = 900,000
Growth rate of population = 7%
Number of year = 19
Find:
Future population in 19 years
Computation:
A = P[1+r]ⁿ
Future population = Current population[1+g]ⁿ
Future population in 19 years = 900,000[1+7%]¹⁹
Future population in 19 years = 900,000[1+0.07]¹⁹
Future population in 19 years = 900,000[1.07]¹⁹
Future population in 19 years = 900,000[3.6162]
Future population in 19 years = 3,254,580
Future population in 19 years = 3,254,580 people (Approx.)

v. State the slope and interpret its meaning in context.
vi. SS(resid)=16.7812. Use this to compute se.
vii. Show what needs to be calculated for a 95% prediction interval for x = 20. (fill in all the values in the equation but do not evaluate.)
r = - 0.98754
Answer:
Slope = - 0.7120
SE = 1.295
Step-by-step explanation:
Given the data:
0 | 33.3
0 | 31.0
3 | 29.8
3 | 27.8
6 | 28.0
6 | 29.0
10 | 25.5
10 | 23.8
20 | 18.3
20 | 15.5
30 | 11.7
Using the relation to Obtian the slope :
Slope, b = r(Sy/Sx)
r = correlation Coefficient ; Sy = standard deviation of Y - values ; Sx = standard deviation of X-values
r = - 0.98754
Slope, b = - 0.98754(7.8471 / 10.884) = - 0.7120
SE = √SSresidual / df
df = n - 2 = 12 - 2 = 10
SSresidual = 16.7812
SE = √(16.7812/ 10)
SE = 1.295

Heyaa!!! Im Pinky! Im here to inform you that your answer is....
Step-by-step explanation:
1st. We need to Distribute:
3(+2)=2(2−)
3+6=2(2−)
Just like That!
2nd. We have to Rearrange terms:
3+6=2(2−)
3+6=2(−+2)
3rd. Distribute One Last Time:
3+6=2(−+2)
3+6= −2+4
4th. Simplify:
3=−2−2
5th. Add 2 to both sides of the equation:
3=−2−2
3+2=−2−2+2
6th. Simplify:
5=−2
7th. Divide both sides of the equation by the same term:
5=−2
5/5 = -2/5
8th. Solve:
x = -2/5
Have an Amazing day!!
