<span>A mathematical sentence that contains one or more variables is sometimes called an open sentence.</span>
Since they are similar, and a side of 10 = a side of 4, the ratio would be 2.5 : 1. You would do 6 * 2.5, which would equal 15, and (15 + 2) / 2 = 8.5 or 17/2
Answer:
a: no the sample size is too small
b: Yes, the distribution is normal with a mean of 40 and standard deviation of 12
Step-by-step explanation:
a: If n < 30, we need to know that the sample is normally distributed or else we can't determine anything. When sample sized get very large, they usually resemble normally distributed data sets so we can still make conjectures even if the data isn't officially normally distributed
b: The question tells us that the sample is normally distributed, so even though n < 30, we can still make conjectures about the population
Answer:60
Step-by-step explanation:
⅟₂ of 30=15
¼ of 60=15
<h3>Half of thirty is 15 so u need to know what ¼ of something makes 15 so all u have to do is times 15 by 4 and there got ur answer this will not go for every question tho</h3>
Toni can carry up to 5 books
1+2+3b=18
combine 1 and 2
3+3b=18
subtract 3 from both sides
3b=15
divide 3 from both sides
b=5
