A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P ( red or blue)
Answer:
5/8Step-by-step explanation:
To find the combined probability we will write as a fraction with the number of occurrences for the specified conditions.
Here, we have 16 marbles total (as 6 + 6 + 4 = 16) and we want to find the probabiliy of choosing either a red or blue marble out of the 16. There are 10 marbles that are either red or blue (as 16 - 6 = 10) so the fraction would be 10/16. However, we still need to get this simplest form.
[tex]\frac{10}{16} = \frac{5}{8}[/tex]
As we cannot simplify 5/8 any further, this is the final answer.
During a food drive, a local middle school collected 8,502 canned food items. Each of the 31 classrooms
that participated in the drive donated about the same number of items. Estimate the number of items
each classroom donated.
Each class donated about
cans.
Answer:
it would be around 274
Step-by-step explanation:
if you divide 8,502 by 31 you will get 274.258064516129, so the estimate would be 274.
each classroom donated about 274 canned food items.
Frank says that 2/10 of the grid below is shaded. Kendra says that 20/100 of the grid is shaded. Who is correct and why?
Answer:
They are both correct because each fraction can simplify down to 1/5.
If you divide 2/10 by 2 you get = 1/5
Divide 20/100 by 20 to get = 1/5

What is the affect on the graph of the linear parent function f(x) equals X when FX is replaced by FX +3
Answer:
The graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).
Step-by-step explanation:
We know that when we add a constant to the input of the parent function, we get a horizontal shift.
The direction of shifting depends upon the value of the added constantly. If the added constant is negative, the shift of the graph will be left and if the added constant is positive, the shift of the graph will be right.
For example, consider the function
f(x)
so adding [tex]3[/tex] in the put i.e. [tex]f(x+3)[/tex] would be a change on the inside of the function, giving a horizontal shift left by 3.
Therefore, the graph of the f(x) will horizontal shift left by 3 when f(x) is replaced by f(x+3).

A cheetah can run at its top speed for about 25 seconds. Complete the table to represent a cheetah running at a constant speed.
Answer: For meters it is 3,000
Step-by-step explanation: Do 120 x 25= 3,000
Step-by-step explanation:
120 x 25 = 3000
270 ➗ 25 = 10.8
120 ➗ 4 = 30
3000 ➗ 25 = 120
270 ➗ 10.8 = 25
Noah has a coupon for 30% off at his favorite clothing
store. He uses it to buy a hoodie and a pair of jeans.
Noah paid $28 for the jeans after using the coupon.
What is the regular price of the jeans?
Answer:
$21.54Step-by-step explanation:
price paid = regular price ( 1 + coupon in percent)
$28 = regular price x (1.3)
regular price = $28 / 1.3
= $21.54
The regular price of the jeans is equal to $93.33.
Let the cost price be C.Given the following data:
Coupon = 30%Selling price = $28To calculate the regular price of the jeans:
Since Noah had a coupon for 30% off, it simply means that he would get a discount of 30% for any clothing he buys at his favorite clothing store. Thus, the cost price of the jean multiplied by 0.3 would give the amount of money to be paid by Noah, which is $28.
Mathematically, the selling price is given by:
[tex]28 = \frac{30}{100} \times C\\\\2800 =30C\\\\C=\frac{2800}{30}[/tex]
C = $93.33

Write an equation in slope-intercept form of the line shown.
Answer:
y = 3/4x - 2
Step-by-step explanation:
slope intercept form: y = mx + b
y-intercept(when x= 0) is given by b
slope is given by m
lets find the slope using the two given points, (4,1) and (8,4)
m = y2-y1 / x2-x1
m = 4 - 1 / 8 - 4
m = 3/4
Now use any of the given points to begin writing your equation, which will help you find the y intercept - ill use (4,1).
1 = 3/4(4) - b
1 = 3 - b
b = -2
now you have m and b so you can finish writing your equation.
y = mx + b
y = 3/4x - 2

Students in a sixth-grade class are raising money for an end-of-year camping trip. So far, they have raised $240. This is 2/3 of the cost of the trip. How much does the trip cost? Please include equations.
Answer:
$360 I think
Step-by-step explanation:
240 divided by 2/3 = 360
I hope this helps, sorry if it isn't the right answer
Answer: $600
Step-by-step explanation:
2/5 = 240 of the trip
1/5 = 120 of the trip
3/5 = 360 of the trip
4/5 = 480 of the trip
5/5= the whole trip $600

A gas has a volume of 5.0 L at a pressure of 50kPa. What happens to the volume when then the pressure is increased 125kPa. The temperature does not change.
9514 1404 393
Answer:
volume goes to 2.0 L
Step-by-step explanation:
At constant temperature, volume and pressure are inversely related. Increasing the pressure by a factor of 125/50 = 2.5 will cause the volume to be reduced by that factor.
volume = 5.0L / 2.5
volume = 2.0 L

When the errors show a non-random pattern in a residual plot, that means that your model probably is not appropriate for linear regression. True or false and why?
Answer: True
The errors represent how far off the guess is to the true value. The points on the residual plot must be scattered randomly around 0, in both positive and negative regions. Ideally, the smaller the errors, the better the fit. So we want these errors to be as close to 0 as possible. This is why we try to minimize the sum of the squared error (SSE) when trying to find the linear regression equation. The r and r^2 value are related to this idea as well.
If we don't have randomly scattered errors, and some pattern shows up, then this means a linear equation is not a good fit. Another model such as a quadratic model may be the better option.
As for the "why" this works, try to think of a person throwing darts. Their accuracy isn't perfect so they'll likely miss on the left and right sides of the target. Stuff on the left is negative territory, while stuff on the right is positive. Each side is fairly equal assuming the thrower isn't biased in some way. That's why we have randomly scattered points in both regions. In the case of a regression line, that's where our guess goes while the actual data point is the observed value. The difference between the two is the error.
I need help with finding x
ill give brainiest to whoever shows work
Answer:
x=-5
Step-by-step explanation:
-3-(7x+5)+9x=x-8+3x+10
Distribute the -1 to the terms in parentheses.
-3-7x-5+9x=x-8+3x+10
Combine like terms on both sides.
-8+2x=4x+2
Add 8 to both sides.
2x=4x+10
Subtract 4x from both sides.
-2x=10
Divide both sides by -2
x=-5
