Isabella pitches for her high school softball team. Of the 7 pitches she throws, 5 are strikes. She uses a standard deck of cards to model her pitches, with hearts, clubs, and spades representing strikes. Which statement about her model is true?
A- Her model can be improved the most by removing all the face cards from the deck. B-Her model cannot be improved. C-Her model can be improved the most by removing all the aces from the deck. D-Her model can be improved the most by removing the queens and kings of hearts, clubs, and spades.
Answer:
B. Her model cannot be improved.
Step-by-step explanation:
We make this conclusion because it seems Isabella's model isn't actually proffering any solution to increase/reduce the number of strikes she has had.
Hence, any changes made do not clearly seem to improve the present model she is using.
Answer:
The correct answer is D!

The LA Dogers hit the most home runs in 2014. The number of home runs accounted for 6% of the entire major league Baseball home run count.If 583 total home runs were hit, then how many did the LA Dogers hit
Given:
Total number of home runs = 583
Home runs hit by LA Dogerse = 6% of the total home runs
To find:
The number of home runs hit by LA Dogers.
Solution:
We have,
Home runs hit by LA Dogerse = 6% of the total home runs
[tex]=\dfrac{6}{100}\times 583[/tex]
[tex]=\dfrac{3498}{100}[/tex]
[tex]=34.98[/tex]
[tex]\approx 35[/tex]
Therefore, LA Dogerse hits about 35 home runs.

Xavier ran 2.5 miles in 12 minutes. How long will it take him to run 1 mile?
Answer:
4.8 minutes
Step-by-step explanation:
2.5/2.5=1
so
12/2.5=4.8
Answer:
4.8 minutes per mile
Step-by-step explanation:
Let mi be miles
Let min be minutes
2.5mi = 12min
Divide by side by the mile to get the unit rate
2.5/2.5 = 12/2.5
You will get 1 = 4.8
Explain what is occurring in each chunk of the graph
Answer:
Please check the explanation.
Step-by-step explanation:
As the given graph includes distance 'd' at the y-axis and time 't' at the x-axis.
so from the distance-time graph, it is clear that the graph includes 5 chunks.
The first chunk of the graph indicates that the object has started traveling. And the distance 'd' is being covered in time 't', as the slope is upward, hence the speed of the object is increasing.
Please note that speed is basically the distance covered per unit time.The second chunk of the graph indicates the no distance is being covered. It means the object is at rest.
The third chunk of the graph indicates that the distance 'd' is being covered in time 't', as the slope is again upward, hence the speed of the object is increasing and the object has started traveling.
The fourth chunk of the graph indicates that the slope is downward, and the object has started traveling to get back to the destination, and eventually, the object has reached the starting point.

A student collected monetary pledges for a fundraiser. One donor pledged to contribute $5 for each mile walked by the student during the fundraising walk up to a maximum of six miles.
A. is the situation continuous or discrete
B.write the domain and range of the situation
Answer:
A. The situation is discrete B. i. { x : 0 ≤ x ≤ 6; x ∈ Z} ii. { C = 5x : 0 ≤ C ≤ 30; C ∈ Z}
Step-by-step explanation:
A. The situation is discrete since we have integral values for the amount paid per mile walked. The amount per mile is $5 and is only paid if a complete mile is walked. So, it is a discrete situation.
B. i. Since 0 miles represents 0 distance and the student walks a maximum of 6 miles, let x represent the distance walked. So the domain is 0 ≤ x ≤ 6 where x ∈ Z where Z represent integers.
{ x : 0 ≤ x ≤ 6; x ∈ Z}
ii. Since at 0 miles the amount earned is 0 miles × $5 per mile = $ 0 and at the maximum distance of 6 miles, the amount earned is 6 miles × $5 per mile = $ 30, let C represent the amount donated in dollars. So the range is 0 ≤ C ≤ $ 30 where C = 5x.
{ C = 5x : 0 ≤ C ≤ 30; C ∈ Z}

Answer:
Point Form: ( 4 , − 5 )
Equation Form: x = 4 , y = - 5
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Point Form: ( 4 , − 5 )
Equation Form: x = 4 , y = - 5
Answer:
(4, - 5)
Step-by-step explanation:
3x - 4y = 32 ........ (1)
5x + 2y = 10 ....... (2)
(2) × 2 + (1)
13x = 52 ⇒ x = 4
3(4) - 4y = 32 ⇒ y = - 5

A scientist measures the temperature of a chemical solution. At the start of the experiment, the solution is at a temperature of -14.06*C. TH decreases 2.9°C each hour. What is the temperature of the solution after 3 hours, rounded to the nearest whole degree?
Answer:
T(3) = -23°C
Step-by-step explanation:
Constant Rate of Change
Given an initial condition of a variable T, To and a constant rate of change m, it's possible to write a model to predict the value of T in time t:
[tex]T(t)=T_o+mt[/tex]
The initial temperature the scientist measures of a chemical solution is To=-14.06°C.
It's known the temperature decreases at a constant rate of -2.9°C each hour, thus the model is:
[tex]T(t)=-14.06-2.9t[/tex]
Evaluating at t=3 hours:
[tex]T(3)=-14.06-2.9\cdot 3[/tex]
[tex]T(3)=-14.06-8.7[/tex]
T(3) = -22.76°C
Rounding to the nearest whole degree:
T(3) = -23°C

if kevin took 1/10 of an hour to use 1/2 of package of napkins. how many hours would it take to use 2 packages?
Answer:
2/5 hours
Step-by-step explanation:
We can write a proportion to solve
1/10 hour x hours
---------------- = -------------------
1/2 package 2 packages
Using cross products
1/10 * 2 = 1/2 x
1/5 = 1/2x

Actually Welcome to the Concept of the Straight lines.
Since there are more than one lines that can land plane safely, we take one of it,
When, X = 10 and Y = 7, so the equation we get as,
y-7 = m(x-10) + c
lets find slope, that is value of m,
y2-y1/x2-x1 = m
so, 9-7/ 7-10 = 2/-3
so, m= -2/3
so the final Equation is,
=> y-7 =(-2/3)(x-10) +c

Find an explicit rule for the nth term of the sequence.
-4, -8, -16, -32, ...
A) an = -4 • 2n - 1
B) an = 2 • -4n + 1
C) an = 2 • -4n
D) an = -4 • 2n
Answer:
An explicit rule for the nth term of the sequence will be:
[tex]a_n=-4\cdot \:2^{n-1}[/tex]
Thus, option (A) is true.
Step-by-step explanation:
Given the sequence
[tex]-4, -8, -16, -32, ...[/tex]
A geometric sequence has a constant ratio r and is defined by
[tex]a_n=a_0\cdot r^{n-1}[/tex]
Computing the ratios of all the adjacent terms
[tex]\frac{-8}{-4}=2,\:\quad \frac{-16}{-8}=2,\:\quad \frac{-32}{-16}=2[/tex]
As the ratio 'r' is the same.
so
[tex]r=2[/tex]
as
[tex]a_1=-4[/tex]
Hence, the nth term of the sequence will be:
[tex]a_n=a_0\cdot r^{n-1}[/tex]
substituting the values [tex]r=2[/tex] and [tex]a_1=-4[/tex]
[tex]a_n=-4\cdot \:2^{n-1}[/tex]
Therefore, an explicit rule for the nth term of the sequence will be:
[tex]a_n=-4\cdot \:2^{n-1}[/tex]
Thus, option (A) is true.

- Mt. Everest is considered the tallest mountain in the world at 8,848 meters above sea level. In fact, the forgest
mountain in the world is Mauna Loa, in Hawai'i, Mauna Loa rises 4, 170 meters from sea level to the top of the
summit, but its base is deep under water. The base of the mountain is at -5,000 meters,
A probe is dropped 7, 500 meters straight down into Mauna Los from its summit.
At what height is the probe, relative to sea level?
meters
How far is the probe from the base of the volcano?
meters
Answer: 10000
A.) 4170m above sea level ;3330m below sea level
B) 1670 m from the base.
Step-by-step explanation:.
Given that:
Mauna Loa :
4,170 meters (from sea level to summit)
-5000 meters (base of mountain to sea level)
Depth of probe dropped from summit of Mauna Loa = 7500 m
Height of probe relative to sea level :
Depth of probe - height of Mauna Loa(from sea level to summit)
7500 m - 4170 m = 3330 m
Hence, height of probe relative to sea level :
4170m above sea level
3330m below sea level
Distance of probe from base of volcano:
Total depth of Mauna Loa = (4170 + 5000) = 9170m
Total depth of probe = 7500 m
Distance of probe from base :
9170 - 7500 = 1670 m
The probe is 1670 m from the base of the volcano.
