Answer:
Probability of viewing television between 5 to 10 hr is 0.6553
Step-by-step explanation:
Given data:
total time period of viewing of per household = 8.35 hr
standard deviation = 2.5 hr
Probability between 5 to 10 hr can be obtained as
= P(Between 5 and 10 hours)
= P(-1.34 < z < 0.66)
= P(z < 0.66) - P(z < -1.34)
determine z value from standard z table
= 0.7454 - 0.0901
= 0.6553

Answer:
<h3>230.65 </h3>Step-by-step explanation:
If two sides are the same (two sides measure 23.66) this means the triangle is an isoceles triangle. The equation for area of an isoceles triangle is as follows:
x base x height.
As you have the size of the base, you need to find the area of the height.
As this turns into a pythagoras' theory question, you need to reacall:
To get the b^2 value we need to divide the total base (22.8) value in two:
22.8 ÷ 2 = 11.4
So, as you have the hypotenuse () and the base (
) we need to find the
value.
To do this we need to subtract the value from the
value:
Plug the values in:
So
Simply square root this to find a:
a = 20.7325
Now we have all the possible value, we need to plug them into the area formula which was:
x base x height
Plug the values in:
= 230.6505
<h3>So the area is 230.65 feet!</h3><h3 /><h2>Hope this helps!</h2>
