Find the slope and y-intercept for this table.

labwork [276]

Answer:

See below:

Step-by-step explanation:

To find the slope, we use the following formula:

$\frac{y_{2} - y_{1} }{x_{2} - x_{1} }$

For this case, we can use (6,60) as the first set of points.

We can use (4,70) as the second set of points.

Now, we can use the formula, 70-60 is for the top of the fraction (10)

We can do 4-6 to find the bottom, which is (-2)

Now, if we add the fraction back we get -> 10/-2 which is -5 for slope!

To find out the y intercept, it in simple words is "What is y when x is 0?".

We can do that by using the slope intercept formula: $y=mx+b$ .

Once we insert our slope which is -2 we get: $y=-2x+b$

We can now substitute a point, lets use (6,60) so we can find out b.

We now get the equation: $60=-5(6)+b$ .

If we solve for that we get 90!

Once we input that, we get, $y=-5x+90$

Now we put in x as 0 and we get our y intercept as 90!

If this answer helped, consider marking as brainliest!!

On Saturday a restaurant used 10 7 ⁄ 9 cans of vegetables. On Sunday they used another 3 4 ⁄ 6 cans. What is the total amount of

Rudik [331]

Answer:

14 4/9 cans

Step-by-step explanation:

We need to add the cans used on Saturday and Sunday

10 7/9 + 3 4/6

We can simplify the fraction 4/6 by dividing the top and bottom by 2

10 7/9 + 3 2/3

To add, we need the fractions to have a common denominator of 9

10 7/9 + 3 2/3*3/3

10 7/9 + 3 6/9

Add the whole numbers 10 +3 = 13

Add the fractions 7/9 + 6/9 = 13/9

13/9 = 1 4/9

Move the whole part of the fraction to the whole numbers

13 + 1 + 4/9

14 4/9

artcher [175]

Answer:

The probability of the carton weight being between 775g and 825g is 0.71

Step-by-step explanation:

Hello!

The variable of interest is

X: the weight of an egg of a certain breed of hen. (g)

This variable is normally distributed with mean μ= 65.9g and standard deviation σ=5.5 g

If a carton (a random sample of 12 eggs) is taken, you need to calculate the probability of it weighting 775g and 825g, symbolically: P(775≤X[bar]≤825)

For this, you have to use the distribution of the sample mean X[bar]~N(μ;σ²/n)

If the carton weights 775g, then its eggs will have an average weight of 775/12= 64.48g

If the carton weights 825g, then its eggs will have an average weight of 825/12=68.75g

P(64.48≤X[bar]≤68.75)= P(X[bar]≤68.75) - P(X[bar]≤ 64.48)

P(Z≤(68.75-65.5)/(5.5/√12)) - P(Z≤(64.48-65.5)/(5.5/√12))

P(Z≤1.89) - P(Z≤-0.64)= 0.971 - 0.261= 0.71

The probability of the carton weight being between 775g and 825g is 0.71

I hope you have a SUPER day!
