Answer: C, 2 3/5
Step-by-step explanation:
- Let's start by making these fractions easily subtractable
7 1/5 = 6 6/5 (1 is equal to 5/5 so we take that from the 7 and add it to the fraction)
4 3/5 remains the same because this is what we are subtracting
7 1/5 - 4 3/5 will be subsituted for 6 6/5 - 4 3/5=? because it's equivilant
I like to break this into two parts to make it less complicated, fraction then number
- Fraction: 6/5-3/5=3/5
- Whole Number 6-4=2
- Combine back into a mixed number
This will give you the proper fraction for the result of your equation
2+3/5=2 3/5
2 3/5
Answer:
<u>The function would be:</u>
<u>Since y should be positive or zero:</u>
So x can get values from 0 to 6.
<u>The domain is:</u>
Answer:
the slope is 4/5
Step-by-step explanation:
well the slope formula is the following:
m= (change in y)/(change in x)
let's take the two following points
(-3,0) and (2,4) so
![x_1=-3\\x_2=2\\y_1=0\\y_2=4](https://tex.z-dn.net/?f=x_1%3D-3%5C%5Cx_2%3D2%5C%5Cy_1%3D0%5C%5Cy_2%3D4)
so
change in y = ![y_2-y_1=4-0](https://tex.z-dn.net/?f=y_2-y_1%3D4-0)
change in x = ![x_2-x_1=2-(-3)=2+3=5](https://tex.z-dn.net/?f=x_2-x_1%3D2-%28-3%29%3D2%2B3%3D5)
so
m=4/5
Answer:
The probability of a student receiving a C in the course is p=0.3.
Step-by-step explanation:
We have a absolute frequency for each of the grades (A to F), of a total of 300 course tests.
It is assumed that this sample gives a dood estimation of the distribution of the grades. Then, we can estimate the probability of obtaining a C in the course usign the relative frequency for C.
The relative frequency is calculated as the division between the absolute frequency (in this case, 90 for a C grade) and the size of the sample (in this example, 300).
![p_C=\dfrac{X_C}{N}=\dfrac{90}{300}=0.3](https://tex.z-dn.net/?f=p_C%3D%5Cdfrac%7BX_C%7D%7BN%7D%3D%5Cdfrac%7B90%7D%7B300%7D%3D0.3)
Answer:
The correct answer is A.
Step-by-step explanation:
Scientific notation has to be a number between 1 and 10, so we know b and d are out. Then, you have to count how many places you'd have to move to get to the end of the number. It's 10 jumps, so the correct answer would be 1.19*10^10.
Hope this helps!
