Which function is graphed below?? TIMED HELP

nadezda [96]

That's the cosine x. The cosine of 0 is 1, so that's how you can tell. The sin of 0 is 0, so that's where the sin graph goes through the y axis

Find the equation of the line using the point-slope formula. Write the final equation using slope-intercept form. (1,2) with a s

Naily [24]

Answer:

$y-2=\displaystyle-\frac{6}{7}(x-1)$

$y=\displaystyle-\frac{6}{7}x+\frac{20}{7}$

Step-by-step explanation:

Hi there!

Point-slope form: $y-y_1=m(x-x_1)$ where m is the slope and $(x_1,y_1)$ is a point that falls on the line

Plug in the slope, -6/7, and the given point, (1,2):

$y-2=\displaystyle-\frac{6}{7}(x-1)$

To write the equation in slope-intercept form, isolate y:

$y-2=\displaystyle-\frac{6}{7}(x-1)\\\\y-2=\displaystyle-\frac{6}{7}x+\frac{6}{7}\\\\y=\displaystyle-\frac{6}{7}x+\frac{6}{7}+2\\\\y=\displaystyle-\frac{6}{7}x+\frac{20}{7}$

I hope this helps!

The average watermelon weighs 8 lbs with a standard deviation of 1.5. Find the probability that a watermelon will weigh between

Andrew [12]

Answer:

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = 0.5932

Step-by-step explanation:

Step 1:-

by using normal distribution find the areas of given x₁ and x₂

Given The average watermelon weighs 8 lbs

μ = 8

standard deviation σ = 1.5

I) when x₁ = 6.8lbs and μ = 8 and σ = 1.5

$z_{1} = \frac{x_{1} -mean}{S.D} = \frac{6.8-8}{1.5} = - 0.8$

ii) when x₂ = 9.3 lbs and μ = 8 and σ = 1.5

$z_{2} = \frac{x_{2} -mean}{S.D} = \frac{9.3-8}{1.5} = 0.866>0$

Step2:-

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = A(z₂) - A(-z₁)

= A(0.866) - A(-0.8)

= A(0.866)+ A(0.8)

check below normal table

= 0.3051 + 0.2881

= 0.5932

Conclusion:-

The probability that a watermelon will weigh between 6.8 lbs and 9.3 lbs.

P(6.8 ≤X≤9.3) = 0.5932
