Recent research has found that 10% of Americans aged 30-49 played tennis in the past 12 months. A local city wishes to test whether this is true in their city as well. If more than 10% of their residents aged 30-49 play tennis, improvements will be made on their tennis courts. A random survey of 200 residents aged 30-49 found that 48 played tennis. Do we have evidence that more than 10% of the residents play tennis? Use α=.05.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

step-by-step explanation:

6.48/4 4 goes into 6.48 1.62 times

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
