The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.
Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.
Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
9y+68+ 5y= 180
14y+68= 180
-68 -68
14y= 112
Y= 8
Now that we know what y is, we can plug it into the equation for angle B and find its actual angle measurement.
9(8)+ 68= 72+ 68= 140
So its 140 degrees.
Answer:
So the value of the test statistic is -0.85.
Step-by-step explanation:
We know that a sample of 1800 computer chips revealed that 53% of the chips do not fail in the first 1000 hours of their use. The company's promotional literature states that 54% of the chips do not fail in the first 1000 hours of their use.
We get that:
We calculate the standar deviation:
We calculate the value of the test statistic:
So the value of the test statistic is -0.85.
1.) 1/4
2.) 25%
First is fraction, sedond is percent
Answer:
27
Step-by-step explanation:
5e-8+2e-1= 180
7e-9= 180
7e=189
e= 27°
