Joey had a large bag of the same amount of blue and orange toy bears. He randomly pulled out a bear and replaced it. The results are 45 blue and 15 orange. What is the experimental probability the next bear he pulls is NOT orange?
*The denominator will be how many times he did the experiment*

Answers

Answer:

use division for the numbers.

Step-by-step explanation:

Answer:

45/60

Step-by-step explanation:

Because the bears that are not orange are blue and there are 45 blue bears.

Since there are 45 blue bears that is the numerator.

There is 60 bears in total so the denominator is 60/.

Declan has n baseball cards. Sam has 4 times as many baseball cards as Declan. Amaya has 7 fewer baseball cards than Sam. Which expression represents the number of baseball cards that Amaya has?

Answers

Answer:

4n-7

Step-by-step explanation:

First, you know that Sam's equation is 4n, since it is 4 times Declan's value n. Next, you take Sam's equation and subtract 7 from that value, since Amaya has 7 fewer cards than Sam. The final equation will be 4n-7.

Answer:

Okay I get it now, N is equal to 4-7.

how do the equations y = mx and y =kx compare plz help me bad answers will be reported

Answers

We can compare y = kx to the slope-intercept form of a line, y = mx + b.

We can see that y = kx is a linear equation with slope k and y-intercept 0.

Hey there!

The difference is that y = kx means the "y directly varies with x", which means that y/x = k. Also, the line of the graph passes directly through the origin. Or, in other words, there is no y - intercept other than (0, 0)

y = mx could have a y - intercept not at the origin. If you have an equation in slope - intercept form, such as y = 5x + 3, than "y" does not directly vary with "x", because you can't get "m" by doing y/x, because first you have to subtract 3. In order to actually find "m", you would have to do (y - 3) / x = m (or, in this case, 5).

Hope this helps! Good luck and have a great day!

how do I solve this
t + 1 = -3

Answers

Solve for t. Simply sense its +1, do the opposite and minus 1 from both sides of the equation. +1 - 1 = 0; -3 -1 = -4. Therefore, t = -4 is the correct solution.

Answer:

-4

Step-by-step explanation:

"t" could be any number.

The equation is basically asking, if you add 1 to a number, and it equals -3, then what number did you add to? To solve this just reverse the equation (subtract 1 from -3), which will get you -4.

"t" is -4

help please u will get good points

Answers

Answer:

A,B,C,E

Step-by-step explanation:

Answer: A and E

For letter A:
5-3x=-3x+4
Combine same variables
So in this case add 3 on both sides for x
Ur left with
5=x+4
subtract 4 on both sides
Your left with
x=1 which is the same thing as saying x

For letter E:
x+6=5+x
Combine same variables
In this case x
So subtract 1 on both sides
Ur left with
c+6=5
Subtract 6 on both sides
Ur left with
x= -1 Which is the same thing as saying -x

I going to say its going to take her about 15 months to invest in the money to get the iPhone. But if you still don't get it, just take a look at my math.

Jenna wants to save => $35/per month

$35 * 14 mo = $490 + $20 = $510

(The $20 is for what Jenna started with, she most likely saved that up too)

So, it will take her about 15 months to get an iPhone.

The rectangular front yard of a house has a length to width ratio of 4:5. If the perimeter of the yard is 90 meters, what is the length of the yard

A. 50 meters
B. 40 meters
C. 25 meters
D. 20 meters

Answers

Answer:

B!

Step-by-step explanation:

If the ratio is 4:5, then that means you can take the 90 and divide it by 9 (4+5) which is 10. You now know that each unit in the ratio is equal to 10 meters. If the length is 4 units, take that 4 and multiply it by 10.
