Answer:
1 and 9/20
Step-by-step explanation:
add your fractions together 7/10 + 3/4
make them have the same denom 14/20 + 15/20
so its 29/20
to get the mixed fraction, divide 29/20 to get 1.45. The 1 is your whole number. Subtract 20 from 29 to get 9, which is what is remaining, and will go over 20.

The line on a graph would show up negative seeing if the slope was negative.
Answer: $1500
Step-by-step explanation:
<u>Given information</u>
Number of puppies = 6
Cost of each puppy = $250
<u>Given expression deducted from the question</u>
Total cost = number of puppies × cost of each
<u>Substitute values into the expression</u>
Total cost = 6 × 250
<u>Simplify by multiplication</u>
Total cost =

Answer:
Lourdes has more brownies.
Step-by-step explanation:
First, you have to find a common denominator. Whatever you do to the bottom of the fraction you do to the top. 5/6 and 4/5 has a common denominator of 30. Multiply both digits in 5/6 by 5. Then multiply both digits in 4/5 by 6. Then you can compare the fractions. With the common denominators, Lourdes should have 25/30 brownies and Zachary has 24/30. Compare.
24/30 < 25/30. So Lourdes has the most brownies!
Answer:
B
Step-by-step explanation:
Consider an event A happening. If we do not have enough data to estimate its actual probability, we may choose a range 0.6 to 0.9 as a first case which indicates we are quite sure it will most likely occur. If however, we have enough data, we may estimate a range of 0.7 to 0.8 as a second case that is more certain on its actual likelihood of occurrence.
Say the actual probability of the event is given as 0.75, in the first case, we can infer the probability interval as 0.75 ± 0.15 (as 0.75-0.15=0.6 and 0.75+0.15=0.9 for the lower and upper bounds respectively). In the second case, we can infer the probability interval as 0.75±0.05 (as 0.75-0.05=0.7 and 0.75+0.05=0.8 for the lower and upper bounds respectively).
Thus, we can see that with more certainty of the event happening (with more data in this case), the probability or prediction intervals are lower.
Hence, in the experiment, we will observe a narrower prediction interval for researcher A who has more (twice as many points) data than researcher B who has fewer points.
