The median is 10.5 because its the middle line in the box and all you have to do is look at it and you can see it
Answer:
Horizontal line
Step-by-step explanation:
Zero slope means that the quotient "rise/run" equals zero.
A zero for a quotient of two numbers implies that the NUMERATOR is zero and the denominator different from zero.
Analyzing what a "rise" of zero means, we understand that there is NO RISE in the graph of the line. And no rise of any type means the line is flat (horizontal).
Answer:
y = -13.75x + 340
120 owls in 2019
Step-by-step explanation:
To find the population in a future year, use the formula y=mx+b since it changes linearly.
So over 4 years the owl population changed from 285-340=-55. Divide by 4 and this is a yearly change of -13.75. This is m.
The y-intercept is the starting point known as b in the equation. Here it is 340.
So the equation is y=-13.75x+340.
In 2019, t=16 so y=-13.75(16)+340 = 120.
Answer:
a) The probability that this whole shipment will be accepted is 30%.
b) Many of the shipments with this rate of defective aspirin tablets will be rejected.
Step-by-step explanation:
We have a shipment of 3000 aspirin tablets, with a 5% rate of defects.
We select a sample of size 48 and test for defectives.
If more than one aspirin is defective, the batch is rejected.
The amount of defective aspirin tablets X can be modeled as a binomial distribution random variable, with p=0.55 and n=48
We have to calculate the probabilities that X is equal or less than 1: P(X≤1).
Answer:
<u>Bob and John can finish the job together in approximately 2.92 hours or 2 hours and 55 minutes</u>
Step-by-step explanation:
Let's recall that the formula for solving this kind of problems is:
T/A + T/B = 1, where T = time working together, A = the time for person A working alone, and B = the time for person B working alone.
Now, replacing with the values we have:
T/5 + T/7 = 1
35 is the Lowest Common Multiple of 5 and 7
5T + 7T = 35
12T = 35
T = 35/12
T = 2.92 (Rounding to the next hundredth) and 0.92 * 60 ≅ 55
T ≅ 2.92 hours (Around 2 two hours and 55 minutes)
