(B) Number of football games played and the position of a football player.
(C) High temperature of the day and number of zoo visitors that day.
(D) Type of beverage ordered and time of day it was ordered.
(E) Brand of cell phone and number of cell phones sold.

Answers

Answer 1

Answer:

The relationship which could be described using correlation, r is; Choice C; High temperature of the day and number of zoo visitors that day.

What is correlation

Correlation is a statistical measure that expresses the extent to which two variables are linearly related (meaning they change together at a constant rate). It's a common tool for describing simple relationships without making a statement about cause and effect.

Correlation is characterized by the two variables being quantitative variables.

Hence, since High temperature of the day and number of zoo visitors that day are quantitative, the relationship can be described as correlative.

A scientist begins an experiment with a petri dish containing a culture of bacteria cells and records the cell growth every hour. At 1 hour, the bacteria had grown to 880 cells, and at 2 hours, had grown to 3,520 cells. Which function can be used to represent the relationship between the number of bacteria cells, y, and the time in hours, x?

Answers

Answer: Hello!

we know that in the first hour, we had 880 cells, and in the second hour we have 3520 cells. The first step is see how much the population changed in this one hour, this can be done by looking into the quotient:

3520/880 = 4

then the population of cells cuatriplied in one hour, and is safe to asume that every hour that pases, the population will catriplied again.

so if the populationat hour 1 is: 880

at hour 2 is: 4*880

at hour 3 is = 4*4*880 and so on.

This can be described with an exponential function as follows

$P(t) = 880*4^(x-1)$

where 880 is the initial population, and x is represents the hours.

These are the choices y = 4 x y = 220(4) x y = 880(4) x y = 880(0.25) x Right..?

2. Which diagram shows a point P an equal distance from points A, B, and C?H

Answers

Answer:

The correct option is (a).

Step-by-step explanation:

The vertices are equidistant from the circumcenter.

Circumcenter of a triangle is a point where the perpendicular bisectors are intersection each other.

In figure (a) the point P is the intersection point of all perpendicular bisector, therefore point P is the circumcenter of triangle ABC and the point P is equidistant from A,B and C.

Therefore option (a) is correct.

In figure (b) the point P is the intersection point of all perpendicular, therefore point P is not the circumcenter of triangle ABC.

Therefore option (b) is incorrect.

In figure (c) the point P is the intersection point of all bisectors, therefore point P is not the circumcenter of triangle ABC.

Therefore option (c) is incorrect.

In figure (d) the point P is the intersection point of all medians, therefore point P is not the circumcenter of triangle ABC.

Therefore option (d) is incorrect.

Henrietta has $120 to buy a new bicycle. She finds the bike that she wants to buy on sale for 20% off the regular price of $150. If there is 6% sales tax, which of the following best describes the amount of money Henrietta has with regards to buying the bike. a. Henrietta has enough before the tax, but not enough after the tax. b. Henrietta has enough money even after the tax. c. Henrietta does not have enough money even before the tax. d. There is not enough information given.

Answers

Given:
Henrietta budget: 120
Original Price of the bike : 150
discount: 20%
sales tax: 6%

150 * 20% = 30
150 - 30 = 120 discounted price

120 * 6% = 7.2 sales tax
120 + 7.2 = 127.20 total cost of the bike

Since Henrietta only has 120, A.) Henrietta has enough before the tax, but not enough after the tax.

Answer:

A. Henrietta has enough before the tax, but not enough after the tax.
