6:35pm, because 35 minutes before 7:10 pm is 6:35pm :)
Answer:
The answer is 137 degrees
Step-by-step explanation:
Add up the two angles you know already
93 + 44 = 137
Then you take that number and subtract it from 180 in order to find the other interior angle.
180 - 137 = 43
So angle LKJ is 43 degree
Now to find the exterior angle you take the missing angles measurement
Which is 43 and subtract it from 180 to get 137
Answer:
Step-by-step explanation:
To find inverse of a function, follow the steps below:
1. replace h(x) with y
2. Interchange x and y
3. Solve for the new y
4. Replace y to 
(this is the inverse function)
<u>Step 1:</u> y = -2/3x+6
<u>Step 2:</u> x = -2/3y+6
<u>Step 3:</u>
<u>Step 4:</u>
This is the inverse function.
Answer:
62.83
because you take 20, divide it by 2 to get the radius then you have the equation 2π(10)
Answer:
Step-by-step explanation:
Hello!
X: the lifespan of a new computer monitor of Glotech.
The average life is μ= 85 months and the variance δ²= 64
And a sample of 122 monitors was taken.
You need to calculate the probability that the sample mean is greater than 86.6 months.
Assuming that the variable has a normal distribution X~N(μ;δ²), then the distribution of the sample mean is X[bar]~N(μ;δ²/n)
To calculate this probability you have to work using the sampling distribution and the following formula Z= (X[bar]-μ)/δ/√n ~N(0;1)
P(X[bar]>86.6)= 1 - P(X[bar]≤86.6)
1 - P(Z≤(86.6-85)/(8/√122))= 1 - P(Z≤2.21)= 1 - 0.98645= 0.013355
The probability of the sample mean is greater than 0.013355
I hope this helps!
