Answer:
3026
30
Step-by-step explanation: Average sum of the female and male's test score is the sum of expected value of each gender:

Assuming x represents the random male selected and y represents the random female selected:

3026
The average sum of their scores is 3026.
Average difference is the difference between the expected value (mean) of each gender:

1528 - 1498
30
The average difference of their scores is 30.
Answer:
37.5 °C
Step-by-step explanation:
The temperature appears to be increasing linearly at the rate of 5 °C in 2 minutes, or 2.5 °C per minute.
1 minute after 4 minutes, when the temperature is 35 °C, we expect it to be 2.5 °C higher, or 37.5 °C.
Answer:
Step-by-step explanation:
mean is found by adding the numbers and dividing the sum by the number while the median is the middle value of the list ordered in an ascending order
I’m not sure if this is a question, but yes, i like to use “PEMDAS”.
Parentheses, exponents, multiply, divide, add, subtract.
You always go in order from left to right!
First you would solve for h(5) by plugging in 5 as your x, then solving it.
h(5) = 5^2 + 1
h(5) = 25 + 1
h(5) = 26
Next you would multiply the 26 by the individual h, which is basically h(1).
h(1) = 1^2 + 1
h(1) = 2
Lastly you multiply your h(1) value by the h(5) value to get your answer.
h(1) • h(5) = 26 • 2
h[h(5)] = 52
