Step-by-step explanation:

Question b has already been answered in part one. This is an exponential function.

C) 7 is the initial number of people who received the email;

7*2^n is the number of people who receive the email on day n;

2 is the factor of which the number of people increases each day.

D) On day 5,

{2}^{5}  \times 7 = 32 \times 7 =224

people will have received the email.

E) 2; 0 (no people has received the email on day 0). The equation is

y =  {2}^{x}  \times 7

With x in the natural numbers

About % of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9 and z = 0.9 z = 0.9 (or w
prisoha [69]

Using the normal distribution, it is found that 63.18% of the area under the curve of the standard normal distribution is between z = − 0.9 z = - 0.9.

<h3>Normal Probability Distribution</h3>

The z-score of a measure X of a normally distributed variable with mean \mu and standard deviation \sigma is given by:

Z = \frac{X - \mu}{\sigma}

  • The z-score measures how many standard deviations the measure is above or below the mean.
  • Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.

The area within 0.9 standard deviations of the mean is the <u>p-value of Z = 0.9(0.8159) subtracted by the p-value of Z = -0.9(0.1841)</u>, hence:

0.8159 - 0.1841 = 0.6318 = 63.18%.

Alex bikes 2 3/4 miles. Then, she runs 1 2/4 miles. The distance she bikes is how many times the distance she runs?
Svet_ta [14]

Answer:

1.83 times

Step-by-step explanation:

Take the distance biked divided by the distance run.

2 3/4 / 1.5 = 1.83 times.

This means that Alex biked 1.83 times more than the distance she ran.

Find the perimeter of the polygon. Assume that lines which appear to be tangent are tangent. Round to the nearest tenth if neces
kherson [118]

Answer:

P=53.6\ units

Step-by-step explanation:

we know that

The <u><em>Two-Tangent Theore</em></u>m states that if two tangent segments are drawn to one circle from the same external point, then they are congruent

so

Applying the Two-Tangent Theorem at each vertex of the triangle

The perimeter of the triangle is equal to

P=2(7.8)+2(8)+2(11)=53.6\ units
