2th bounce- 80
5th Bounce- (-)200
9th Bounce- (-)560
Every time the ball bounces it loses 40cm because on the first bounce 160cm-120cm=40cm
And the score goes down by 40 every time and since we go into the negatives the negatives sometimes add on top of each other
Answer:
the answer is a
Step-by-step explanation:
Well, you know that the sum of those two numbers aren't zero, as they aren't additive inverses of each other. The sum of these numbers will, furthermore, take the sign of the "greater" number without its sign. For example, 2-3 would be negative, since the negative sign of "3" is of the greater number without its sign.
Answer:
Mean: 65.25
Median: 70.5
Mode: 70
Step-by-step explanation:
Mean is the sum of the set of numbers divided by the number of numbers in the set.
20+68+70+70+71+72+75+76=522
522/8=65.25
The median is the number that is in the middle of the set when put in numerical order.
Since there is an even amount of numbers, the two middle numbers are 70 and 71, so you would take the mean of these two numbers to find the median.
70+71=141
141/2=70.5
The mode is the number that occurs most frequently in the set.
70 appears more times than any other number, therefore it is the mode.
Answer:
B.0.15
Step-by-step explanation:
To approximate a binomial distribution as a normal distribution, two conditions must be met:
np > 10
nq = n (1−p) > 10
Here, n = 250. Check each value of p to see if it meets the conditions.
A. p = 0.03
np = 7.5, nq = 242.5
B. p = 0.15
np = 37.5, nq = 212.5
C. p = 0.02
np = 5, nq = 245
D. p = 0.97
np = 242.5, nq = 7.5
E. p = 0.99
np = 247.5, nq = 2.5
Of the five choices, only B meets both conditions.
