PLEASE HELP

Mathematics
1 answer:
jeka943 years ago
7 0

Answer:

91.92%

Step-by-step explanation:

Given that:

Mean (μ) = 6.2, standard deviation (σ) = 1.5

Z score is a measure in statistics to determine the relationship of a measured value with the mean. It is given by the equation:

z=\frac{x-\mu}{\sigma}

To calculate the probability that a patient has a blood test result less than or equal to 8.3, we need to calculate the z score of 8.3

For x = 8.3, the z score is:

z=\frac{x-\mu}{\sigma}=\frac{8.3-6.2}{1.5} =1.4

From the probability distribution table:

P( x ≤ 8.3) = P(z < 1.4) = 0.9192 = 91.92%

Answer:

Width = 15 feet

Length = 45 feet

Step-by-step explanation:

You need to fence in a rectangular piece of land for your dog to run and play. The length is 3 times the width. If the perimeter is 120 ft, what are the dimensions of your very own dog park?

Perimeter of a rectangle = 2L + 2W

The length is 3 times the width.

L = Length = 3W

W = Width

P = 120 ft

Hence:

120 = 2L + 2W

120 = 2(3W) + 2W

120 = 6W + 2W

120 = 8W

W = 120/8

W = 15 feet

Solving for Length

L = 3W

L = 3 × 15 feet

L = 45 feet

Therefore, the dimensions of your very own dog park is

Width = 15 feet

Length = 45 feet

I just need a little help on this ??! Please.

1. Since it's m - 7 you would have 7 to both sides so you would in fact have m < 13. If you double check your answer, you see that if m is say 12 (because 12 is obviously less than 13), 12 - 7 < 6

2. Again, use the same process on this problem as the first one. Add 8 to each sides because it's you're subtracting 8 from n. So you end up with n > 13. Check your answer. Say n is 14. 14 - 8 > 5

3. This one is different because you are adding 5 to p. So in order to get p by itself, you need to subtract 5 from both sides. p < 5. Say p is 4, 4 + 5 < 10.

When working with problems like these, you need to isolate the variable on one side and get it by itself.
