Answer:

Alicia had 61 pencils

Step-by-step explanation:

Alicia had 76 pencils at the end, gave 18 pencils, and received a total of 33 pencils. 33-18 = 15. Alicia gains 15 pencils. To figure out how many she already had we subtract 76 to 15. 76-15 = 61. To check this we can make an equation. 61-18+10+23 = 76. 76 = 76 so Alicia had 61 pencils in the begginning.

If this helped I would appreciate it if you marked me Brainliest. Thank you and have a nice day!

Factoring:

FOIL (first, outer, inner, last) method

(a+b)(c+d) = 0

ac+ad+bc+bd = 0

Zeros:

(x+a)(x+b) = 0

x+a = 0, x= 0-a

A plumber has a set fee for a house call and charges by the hour for repairs. The total cost of her services can be modeled by c
Lostsunrise [7]

Answer:

1, 2 and 3

Step-by-step explanation:

Let

t -----> the number of hours the job takes

C(t) -----> the total cost for the service

we have

C(t)=125t+95

This is the equation of a line in slope intercept form

where

The slope m is equal to m=125\ \frac{\$}{h}

The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)

therefore

<u><em>The statements that are true</em></u>

1 a house call fee costs $95

2 the plumber charges $125 per hour

3 the number of hours the job takes is represented by t

The coefficient of determination is used to: compute correlations for truncated ranges. compare the relative strength of coeffic
kozerog [31]

Answer: compare the relative strength of coefficients.

Step-by-step explanation: The Coefficient of determination usually denoted as R^2 is obtained by taking the squared value of the correlation Coefficient (R). It's value ranges from 0 to 1 and the value obtained gives the proportion of variation in the dependent variable which could be attributed to it's correlation or relationship to th independent variable. With a R^2 value close to 1, this means a large portion of Variation in a variable A could be explained due to changes in variable B while a low value signifies a low variance between the variables. Hence, the Coefficient of determination is used in comparing the relative strength of the Coefficients in other to establish whether a weak or strong relationship exist.

wolverine [178]

Good morning

______

Answer:

___________________

Step-by-step explanation:

2/3 = (2*4)/(3*4)=8/12

3/4 = (3*3)/(4*3)=9/12

Since 9/12>8/12 then 3/4>2/3
