Answer:
Step-by-step explanation:
The height of the heater is about 89.3 in.
You can solve this problem with the Pythagorean Theorem. The base is a square. So half way across the middle will the right under the tip of the pyramid. We can use the measurement with the slant height to write and solve the equation below.
23.8^2 + x^2 = 90.1^2
x will be about 89.3.
Mark brainliest please if the answer is correct
Answer:
The first blank: not equal
The 2nd blank: not right triangle (it's acute triangle)
The 3rd blank: equal
The 4th blank: it's right triangle
Step-by-step explanation:
4^2 = 3^2 + 3^2
<=> 16 = 9 + 9
<=> 16 = 18 ( nonsense)
so triangle LKJ is not right triangle
5^2 = 4^2 + 3^2
<=> 25 = 16 + 9
<=> 25 = 25 ( make sense)
so triangle ABC is right triangle
Done!! :))
Answer:
Option A - 0.9938
Step-by-step explanation:
Given : Assume that blood pressure readings are normally distributed with a mean of 118 and a standard deviation of 6.4. If 64 people are randomly selected.
To find : The probability that their mean blood pressure will be less than 120?
Solution :
The formula to find the probability is
Where, X is the sample mean
is the population mean
is the standard deviation
n=64 is the number of sample
The probability that their mean blood pressure will be less than 120 is given by,
From the z-table the value of z at 2.5 is
Therefore, Option A is correct.
The probability that their mean blood pressure will be less than 120 is 0.9938.
Answer:Angle MNO=105°
x=21°
Step-by-step explanation:Angle MNO+Angle TUV=180°
75+5x=180°
5x=105°
x=21°
Angle MNO=105°
