Answer:

Step-by-step explanation:

Z = (x-µ)/(s/√n)=(98.5-98.2)/(0.62/√19) = 2.11

left tail p-value = 0.9826

so 98.26% are lower.

Which techniques can be used to evaluate the expression 12.75/<br><br> 1.5
sergeinik [125]

Answer:

8.5

Step-by-step explanation:

Given the expression 12.75/1.5. The technique in solving the division expression is as shown

First we can write the decimals as fraction as shown;

12.75 = 1275/100

1.5 = 15/10

12.75/1.5 = (1275/100)÷(15/10)

12.75/1.5 = 1275/100×10/15

12.75/1.5 = 1275/10 × 1/15

12.75/1.5 = 1275/150

12.75/1.5 = 8.5

Hence the result of the division is 8.5

a parallelogram has one angle that measures 55 degrees. what are the measures of the other angles in the parrelogram.
Ugo [173]

a parallelogram has four sides so all its angles add up to make 360

the angle across from the 55 would also be a 55 equaling a 110 degrees angle leaving you with 250 so your other two angles both equal 125

There is no solution to the equation cscx=0.<br> True or False
Svetradugi [14.3K]

Answer:

True

Step-by-step explanation:

First, we need to recognize that

csc(x)=\frac{1}{sin(x)}

Now, we can try to solve

\frac{1}{sin(x)} =0

Multiply each side by sin(x)

1=0*sin(x)\\\\1=0

As we end up with an answer that cannot be true, we know that there is no solution.

Another method to solve this would be graphing the function y=csc(x)

When graphed, it can be seen that there is an asymptote at x=0 meaning that there is no value for x=0.
