Answer:
-7/4
Step-by-step explanation:
8x=-14
X=-14/8
X=-7/4
The answer to the question
Answer:
Given all right triangles
<u>Use Pythagorean to find the missing side:</u>
- a² + b² = c², where c- hypotenuse
=1=
- x² = 6² + 3² = 45
- x = √45
- x = 6.7
=2=
- x² = 12² + 5² = 169
- x = √169
- x = 13
=3=
- x² = 2² + 5² = 29
- x = √29
- x = 5.4
To solve this problem, we make use of the formula for
Confidence Interval:
Confidence Interval = X ± z * σ / sqrt (n)
where X is the mean value, z is the z score which is taken
from the standard tables, σ is the standard deviation, and n is the number of
samples
z = 1.645 (at 90% Confidence Level)
Substituting the values into the equation:
Confidence Interval = 94 ± 1.645 * 12 / sqrt (70)
Confidence Interval = 94 ± 2.36
Confidence Interval = 91.64, 96.36
Therefore at 90% confidence level, the blood pressure
reading ranges from 91.64 mmHg to 96.36 mmHg.
The way to get the answer is to find out how much each person goes every 1 second. It would make your life a lot easier
To find how far they traveled per second you would divide the both numbers in order to see how far they traveled per second.
Mai: 15 ÷ 6 = 2.5 meters per second.
Priya: 22 ÷ 10 = 2.2 meters per second.
Mai was moving faster than Priya.
