Leonardo read that his reptile food should be given at a temperature of 72.5°F. He keeps the food in the freezer at –4°F. He has

found that if he sets the food on his reptile’s hot rock, the temperature rises 8.5 degrees each hour. How many hours will it take for the reptile food to reach 72.5°F? 72.5 = -4 + 8.5h 76.5 = 8.5h 8 hours 9 hours 9.5 hours 12

Graph y ≥ -x^2 - 1. Click on the graph until the correct graph appears.
Nitella [24]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y\geq -x^{2}-1

The solution of the inequality is the shaded area above the solid line of the equation of the  parabola y= -x^{2}-1

The vertex of the parabola is the point (0,-1)

The parabola open downward (vertex is a maximum)

using a graphing tool

One in a hundred million people is a genius. If they are a genius, the probability that the person is acting extremely quirky is
Mila [183]

Answer:

The correct option is E) About 1 in a million.

Step-by-step explanation:

Consider the provided information.

It is given that one in a hundred million people is a genius.

Let G represents the Genius and Q represents the quirky.

We need to find the probability that someone is acting quirky- what is the probability that they are a genius.

The probability that person is quirky is: P(Q)=0.999\cdot0.00000001+0.01\cdot0.99999999

The probability of P(Q\cap G)=0.999\cdot0.00000001

Hence, the required probability is:

P(G|Q)=\frac{P(Q\cap G)}{P(Q)}

P(G|Q)=\frac{0.999\cdot0.00000001}{0.999\cdot0.00000001+0.01\cdot0.99999999}

P(G|Q)\approx 9.98999\times10^{-7}

Which is near about 1 in a million.

Hence, the correct option is E) About 1 in a million.

If a set of data has mean 60 and variance 9 then it's coefficient of variation is
loris [4]
Coefficient of variation is calculated by dividing the standard deviation by the mean multiplied by 100. Given a data set with mean equal to 60 and variance equal to 9, we can calculate the coefficient of variation by finding the value of the standard deviation which is the square root of the variance. so standard deviation is equal to square root of 9 which is 3. Then, the coefficient of variation is equal to 3/60*100 which is equal to 5%.

What additional information would prove that LMNP is a rectangle? The length of LM is and the length of MN is . The slope of LP
kumpel [21]

Answer:

The correct answer is diagonals are equal and bisect each other.

Step-by-step explanation:

A rectangle is a quadrilateral with opposites sides equal in length and all interior angles equal to 90°. Opposite sides are parallel and adjacent sides are perpendicular. Diagonals in a rectangle are equal in length and they bisect each other. If we want to draw a circumcircle, then the point of intersection of these diagonals give the circumcenter.
