Identify the domain of the function shown in the graph. choices:

A. y = 1.5
B. x < y < 7
- -
C. x is all real numbers
D. -7< y < 7
- -

please help will mark brainliest if you’re RIGHT and an extra 50 points :)) the - mean how the < have a line under it i tried to make it look like it lol

The weights of players in a basketball league are distributed normally. the distance (d) of each player's weight (w) from the mean of 86 kilograms was computed as follows: d = |w - 86| if d is greater than 7 for approximately 5% of the players, what is the approximate standard deviation of the players' weights? a. 1.75 kilograms b. 3.5 kilograms c. 4.3 kilograms d. 7 kilograms

When 142 is added to a number the result is 64 more then 3 times the number. option 35 37 39 41

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
