Answer:
2.75 dollars
Step-by-step explanation:
If 7 boxes cost 19.25 dollars to get one box you would divide 19.25 by 7
Multiply 65 by .2 and then take that number and subtract it from the original 65. So it would be 65 - 13 = 52
Answer:
1.8 Kg
Step-by-step explanation:
a week- 3kg rice
every day-0.6 kg rice
therefore, multiply 3 kg by 0.6kg
3kg x 0.6kg =1.8 kg
he will have 1.8 kg rice after 4 days
have a great day !
Answer: 22.5 degrees
Step-by-Step Explanation:
As we can see, we are given a line, which is a straight angle. Hence, it will be of 180 degrees.
=> All the angles sum up to 180.
Therefore,
=> 3x + x + 90 = 180
= 4x + 90 = 180
= 4x = 180 - 90 = 90
=> x = 90/4 = 22.5
Therefore, x = 22.5 degrees
Verification:
=> 3x + x + 90 = 180
= 3(22.5) + 22.5 + 90 = 180
= 67.5 + 22.5 + 90 = 180
= 90 + 90 = 180
=> 180 = 180
=> LHS = RHS
Answer:
C. The college spread is best described by the IQR. The high school spread is best described by the standard deviation.
Step-by-step explanation:
If data is normally distributed we use Standard deviation otherwise we use Interquartile Range (IQR) for measuring the spread.
Further, data is said to be normally distributed if Mean = Median = Mode.
So, High School data is normally distributed but College data is not.
So, We measure the spread of College data by IQR and High School data by Standard Deviation.
Thus, Option C is the only correct option.
