4.The zoo has 112 types of reptiles and amphibians in their exhibits. There are 72 types of reptiles, and the
rest are amphibians. How many more types of reptiles are there than amphibians in the exhibits?

Answers

Answer:

There are 35 more types of reptiles than amphibians

Step-by-step explanation:

112-72=40

75-40=35

The 40 is the number of amphibians and if you do the number of reptiles minus the number of amphibians (75-40) you get how many more reptiles there are than amphibians.

Final answer:

The zoo has 32 more types of reptiles than amphibians. This was determined by subtracting the number of amphibians from the number of reptiles.

Explanation:

The subject of this question is mathematics, specifically a problem requiring the subtraction operation to determine the difference between two numbers. When you are told there are 112 types of reptiles and amphibians at the zoo and 72 of them are reptiles, you are being asked to find out how many are amphibians. To do this, you simply subtract the number of reptiles from the total number of amphibians and reptiles, which is 112 - 72 = 40. Now, the student asked how many more types of reptiles there are. Since there are 72 reptiles and 40 amphibians, you would find the difference by subtracting 40 from 72, giving the result of 32. So, there are 32 more types of reptiles than amphibians at the zoo.

50 points! A $60 sweater is marked "8 % off." If there is a sales tax of 7%, will the actual amount paid for the sweater be greater, less than, or equal to $60? Explain your answer and show all work.

Answers

60*0.08 Multiply the price of the sweater by 0.08, or 8%
4.8 solution
60-4.8 Subtract discount from original price
55.2 solution
7/100=a/55.2 construct formula to find sales tax
a=3.864 solution
55.2+3.864 add solution to discounted price
59.064 solution
$59.06 round down to 59.06

It will be less than 60 dollars because, according to the work shown, 59.06<60.

60 x 8% = 4.8 4.8 discount
60 - 4.8 = $55.2 pricewith discount
55.2 x 7% = 3.86 tax
55.2 + 3.86 = $59.06 so it would be less than $60.00.

I have 2 questions to ask 1 is divide 180 degrees in a ratio of 4,5 and 9the other one is divide 42 in a ratio 1 2 and

Answers

Here's how to do dividing in a certain ratio:

-- You want to divide up the whole thing in the ratio of
4 parts, 5 parts, and 9 parts.

-- How many parts all together ? (4 + 5 + 9) = 18 parts all together.

-- The whole thing is 180, and that's 18 total parts.
So each part is (180/18) = 10 degrees.

4 parts = (4 x 10) = 40
5 parts = (5 x 10) = 50
9 parts = (9 x 10) = 90.

Check: (40 + 50 + 90) = 180 . yay!

If a seed is planted, it has a 75% chance of growing into a healthy plant.If 6 seeds are planted, what is the probability that exactly 1 doesn't grow?

Answers

Final answer:

Using the binomial probability formula, the probability that exactly 1 out of 6 seeds doesn't grow is approximately 0.119 or 11.9%.

Explanation:

This question revolves around the concept of binomial probability. The binomial distribution model is an appropriate statistical model here since there are a fixed number of trials (6 seed plantings), each trial (seed planting) is independent, and each trial results in one of two outcomes: success (plant grows) or failure (plant doesn’t grow).

The binomial probability formula is P(X=k) = C(n, k)*(p^k)*(q^(n-k)), where 'n' is the number of trials (6 in this case), 'k' is the number of 'successes' we're interested in (5 in this case, since we want only 1 seed - out of 6 - not to grow), 'p' is the probability of success, and 'q' is the probability of failure.

Here, to calculate the probability, p (probability of successful growth) is 0.75 and q (probability of not growing) is 0.25 (= 1 - 0.75).

So, P(5 plants grow and 1 doesn’t) = C(6, 5) * (0.75^5) * (0.25^1) = 0.119.

So, the probability that exactly 1 out of 6 seeds does not grow is approximately 0.119 or 11.9%. This scenario is also known as binomial distribution scenario.
