You know that 30% of a number is close to 25. What do you know about 90% of that number?
Answer:
90% is close to 75
Step-by-step explanation:
90% of a number would be 3 times 30% of a number. As a result we can assume 90% of the number would be around 3(25) or 75
A researcher measures the amount of food consumed by each dog in her lab. She finds that the mean amount eaten by the 10 dogs is 14 oz. The sum of squared deviations is 220. What is the variance for this data set
Using statistical concepts, it is found that the variance for this data set is of 22 oz squared.
What are the mean and the variance of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The variance of a data-set is given by the sum of the differences squared between each observation and the mean, divided by the number of values.
From the second bullet point, the variance can also be interpreted as the sum of squared deviations divided by the sample size.
In this problem, the sum of squared deviations is 220 and the sample size is 10, hence, the variance for this data set is of 22 oz squared.

When the light turns green, John accelerates straight down the road at 1.8 m/s for 8 seconds. What is his final velocity at the end of those 8 seconds
Acceleration is the rate of change of velocity over time
His final velocity is 14.4 meters per second
How to determine the final velocityFrom the question, we have:
Initial velocity: u = 0 m/sTime = 8 secondsAcceleration = 1.8 m/s^2Using the first equation of motion, we have:
[tex]v = u + at[/tex]
So, the equation becomes
[tex]v = 0 + 1.8 * 8[/tex]
[tex]v =14.4[/tex]
Hence, the final velocity is 14.4 meters per second

Area is 220 cm²
Step-by-step explanation:
Firstly divide the polygon into rectangle and triangle
For rectangle area
Area = A = L × W = 11 × 18 = 198 cm²
For triangle
Area = A = 1/2 bh = 1/2 × (15-11) × (18-7) = 1/2 × 4 ×11 = 44/2 = 22 cm²

Answer: B) The coordinate of L is (3,-2).
Step-by-step explanation:
Given that L is the midpoint of JK, we can apply the following equation to obtain the coordinates of point L:
L=(5+1/2, 3-7/2)
As a result of resolving this, we obtain
L=(6/2, -4/2)
L=(3,-2)
Therefore the answer is (3,-2)

Answer:
127
Step-by-step explanation:
The sum of 7 terms of the series 1 +2 +4 +... with first term 1 and common ratio 2 is given by ...
Sn = a1 × (r^n -1)/(r -1) . . . . . . first term a1, common ratio r
S7 = 1 × (2^7 -1)/(2 -1) = (128 -1)/1 = 127
At the end of 6 months, the club will have 127 members.
What’s the missing number in sequence 127, 144, 48, 66, 33, ?
The missing number in the sequence is 52.
What is the missing number in the sequence?In order to determine the missing number, the pattern in the sequence has to be determined.
The difference between the second and first number is 144 - 127 = 17
The third number is 3 times smaller than the second number: 144 / 48 = 3
The difference between the fourth number and the third number is 66 - 48 = 18.
The fifth number is 2 times smaller than the fourth number: 66/33 = 2
Based on this sequence, the sixth number would be 19 more than the fifth number. 33 + 19 = 52
