Answer:

y= 2/3x +1

Step-by-step explanation:

The y intercept is 1 It crosses the y axis at 1. So the point is (0,1)

Another point on the line is (3,3)

We can calculate the slope

m = (y2-y1)/(x2-x1)

= (3-1)/(3-0)

=2/3

The equation for a line is y=mx+b where m is the slope and b is the y intercept

y= 2/3x +1

Answer: C. y= 2/3x+1

Step-by-step explanation:

(3,3)

(6,5)

5-3=2

6-3=3

2/3 is slope then

y-3=2/3(x-3) solve and the answer is c

Normal distribution HELP

Answer:

0.0351478382 (To be precise)

Step-by-step explanation: Can I get brainliest? Thanks

1. Normal Distribution --> Z ~ (0,1^2)

2. Use normalcdf(lower bound, upper bound, μ, σ) function on a graphing calculator

P(Z≥103.53) = normalcdf(103.53, 1e99 [default], 80, 13)

P(Z≥103.53) ≈ 0.03

3. μ+σ ≈ 13.59% According to Z-distribution chart

80+13=93

So about 93 exceed only the top 16% (estimated answer not exact)

Darren wins a coupon for $4 off the lunch special for each of five days he pays $75 for his 5 lunch specials write and solve an

Valentin [98]

The original price for one lunch special is $19.

Explanation

The original price for one lunch special is 'p' dollar.

He wins a coupon for $4 off for each of five days. That means , he needs to pay $(p-4)$ dollar each day.

So, the total amount needed to pay for 5 days $= 5(p-4)$ dollar

Given that, he pays $75 for his 5 lunch specials. So the equation will be.....

$5(p-4)= 75\\ \\ 5p-20=75\\ \\ 5p= 75+20\\ \\ 5p= 95\\ \\ p=\frac{95}{5}=19$

So, the original price for one lunch special is $19.

Step-by-step explanation:

7/9 - 2/8 x 4/9

Reduce the fraction.

7/9 - 1/4 x 4/9

Reduce the numbers:

7/9 - 1/9

Subtract the fractions.:

Messi kicks a soccer ball from a position that is 3 meters from a sideline and 4 meters from a goal

Katarina [22]

Answer:

$( 4.8 ,7.6)$

Step-by-step explanation:

We want to find the point, B(x,y) that divides the directed line segment from Messi, M(3,4) to S(6,10) in the ratio m:n=3:2

We use the section formula:

$( \frac{mx_2+nx_1}{m + n} ,\frac{my_2+ny_1}{m + n})$

We substitute the coordinates and the ratio into the section formula to get:

$( \frac{3 \times 6+2 \times 3}{3 + 2} ,\frac{3 \times 10+2 \times 4}{3+ 2})$

We simplify to get:

$( \frac{18+6}{5} ,\frac{30+8}{5})$

This gives us:

$( \frac{24}{5} ,\frac{38}{5})$

$( 4.8 ,7.6)$
