Please please help me The incubation time for Rhode Island Red chicks is normally distributed with mean of 21 days and a standard deviation of approximately 1 day. If 1000 eggs are being incubated, how many chicks do we expect will hatch?

a. In 19 to 23 days?

b. In 22 days or more?

c. In 21 days or fewer?

d. In 18 to 21 days?

e. In 19 days or fewer

f. In 19 to 24 days?

g. In 18 to 24 days?

h. In 18 days or more?

Solve the system of equations. y= 2x y= x^2 - 15

Solve for x -2.3(r - 1.2 ) = -9.66 enter you answer as decimal.

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function. how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
