A shop has determined that the number of bottles of water they sell on a summer day is a function of the day’s high temperature,
Alik [6]

Answer:

  •          T=t+94

                 Where T is the hight temperature and t is the day

Explanation:

The table shows that every day the<em> High temperature, T (degrees F) </em>increases 1 unit.

Then, this is a linear function with slope = 1ºF / day.

You can use the point-slope equation to determine the <em>function of the high temperature:</em>

  • Point-slope equation:

       y-y_1=m(x-x_1)

  • Choose any point from the table and m = 1. I will use the first point (1,95)

  • m = 1
  • x₁ = 1
  • y₁ = 95

Substitute:

        y-95=1(x-1)\\\\y=x-1+95\\\\y=x+94

Make the variables  y = T, and x = t:

     T=t+94

Answer:

EBC and ABE, as well as ABD and ABE

Step-by-step explanation:

Supplementary angles form an 180 degree angle. In other words, they form a straight line.

EBA and DBC are each greater than 90 degrees and are vertical angles, not supplementary angles.

EBC and ABE form a straight line. So they are supplementary angles.

ABD  and ABE form a straight line. So  they are also supplementary angles.

CBE and ABD are each less than 90 degrees and are vertical angles, not supplementary angles.

So, EBC and ABE, as well as ABD and ABE are the correct choices.

Fifteen people have been exposed to a particular disease. Each one independently has a 40% chance of contracting the disease. A
valina [46]

Answer: e. .0950

Step-by-step explanation:

Let X be the number of people that can be cure from disease.

Since each people independently has a 40% chance of contracting the disease.

So , X\sim Binomial(n=15,p=0.40)

A hospital has the capacity to handle at most 8 cases of the disease.

Binomial distribution formula : P(X=x)= ^nC_xp^x(1-p)^{n-x}

Then , the probability that the hospital’s capacity will be exceeded

P(X>8)=1-P(X\leq8)\\\\=1-0.905\ \ [\text{Using Binomial distribution table for n=15 , x=8 and p=0.4.}]

=0.095

Hence, the probability that the hospital’s capacity will be exceeded is e. .0950.

Thus , the correct option is e. .0950.
