Answer:

5

Step-by-step explanation:

Step 1. Get two points off the graph

Points: (-70, 0) and (-60, 50)

Step 2. Use the two points to find the slope

m = slope

m = change in y/change in x

m = y2 - y1/x2 - x1

m = 50 - 0/-60 - -70

m = 50/10

m = 5/1

m = 5

The slope is 5

Krystal went To the carry out to purchase some items. She purchased four bottles of pop, three candy bars, and two bags of chips

Sunny_sXe [5.5K]

Answer:

Equation to determine crystals total bill (T) =(7.7+2x) - 1.50

Step-by-step explanation:

Given:

Number of bottles of pop purchased = 4

Number of candy bars purchased = 3

Number of chips bag purchased = 2

Cost of per bottle of pop = $1.25

Cost of per candy bar = $.90

Cost of the coupon = $1.50

To Find :

Equation to determine crystals total bill (T) given the cost of one bag of chips = ?

Solution:

Let the cost of one chips bag be x

Cost of 4 bottles of pop

=> $4 \times 1.25$

=>$ 5

Cost of 3 candy bars

=> $3 \times 0.90$

=>$ 2.7

Cost of 2 bags of chips

=> $2 \times x$

=>$ 2x

Now the total cost of the bill is

T = 5 + 2.7+ 2x

T =7.7+2x

Also Krystal had a coupon worth $1.50, the cost of the ticket will be

T =(7.7+2x) - 1.50

ioda

Answer:

200 mL

Step-by-step explanation:

If x is the volume of solution B:

0.06 (500) + 0.20 x = 0.10 (500 + x)

30 + 0.20 x = 50 + 0.10 x

0.10 x = 20

x = 200

According to records from 50 years, there is a 2/3 chance of June temperatures being above 80 F. Azul needs to find the probabil

Brrunno [24]

Record of june temperature of last 50 years

Probability of June temperature being above 80° F from last 50 years

$=\frac{2}{3}$

It means , out of 30 days ,there are only 20 days , in which temperature is above 80°F.

⇒Probability that it will be above 80° F for 20 or more days this June

$=\frac{20+x}{30}$

where, x is the number of extra days after 20 days in month of june, when temperature is above 80°F.

Value of this Probability will be in between

$\frac{2}{3}\leq P \leq 1$

Now, what Azul wants

To find the probability that it will be above 80° F for 20 or more days this June.

The Simulation given is

⇒There are 30 days in June. If we use a number cube with the numbers 1-6 and assign 1-4 as a temperature above 80° F and 5-6 as a temperature 80° F or below.

Total number of numbers on number cube ={1,2,3,4,5,6}

Favorable Outcome={1,2,3,4}=Temperature above 80° F

Temperature 80° F or below ={5,6}

⇒Probability of getting number {1,2,3,4} on the number cube when rolled once,that is Temperature above 80° F

$=\frac{4}{6}\\\\=\frac{2}{3}$

⇒Probability of getting number {5,6} on the number cube when rolled once, that is Temperature 80° F or below

$=\frac{2}{6}\\\\=\frac{1}{3}$

This is Incorrect Simulation, as there are chances that , there can be more than 20 days out of 30 days when Temperature goes above 80° F.But Here we have got Probability of temperature being above 80° F for 20 days only, not more than 20 days, which is $=\frac{2}{3}$

Not,a number

$\frac{2}{3}< \text{Probability} \leq 1$ .

Soloha48 [4]

X-(4.5+1.5+1+3)= 8
x-10=8

x= 18

He took $18 to the fair. You take his original amount and subtract the things he paid for/bought to get what he came home with. I hope it helps!
