What is the point -slope form of a line with slope -4 that contains the point (-2,3)

Arada [10]

Answer:

y - 3 = -4 (x +2)

Step-by-step explanation:

Point slope form is

y -y1 = m(x-x1) where m is the slope and ( x1,y1) is a point on the line

y - 3 = -4 (x - -2)

y - 3 = -4 (x +2)

On a clear day you can see about 25.2 miles from the upper observation platform of the Eiffel tower in Paris. Using the formula

fredd [130]

Answer:

D. 914 feet

Step-by-step explanation:

We are given the distance that a person can see on a clear day from the upper observation platform of the Eiffel tower in Paris. We are then required to estimate the height of the upper observation platform using the formula;

$d=\frac{5}{6}\sqrt{h}$

Where d is the distance and h the height of the upper observation platform. The first step would be to solve for h, that is make h the subject of the formula in the above equation;

We multiply both sides of the equation by the reciprocal of 5/6 which is 6/5;

$\sqrt{h}=\frac{6}{5}d$

The next step is to eliminate the square root on the Left Hand Side of the equation by squaring both sides;

$h=1.44d^{2}$

Given d is 25.2, h becomes;

$h=1.44*25.2^{2}\\h=914.4576$

To the nearest whole number, h becomes 914

The following random sample from a population whose values were normally distributed was collected.10 8 11 11The 95% confidence

Margaret [11]

Answer:

Step-by-step explanation:

First to find the sample mean

Xbar= summation x/n= 40/4= 10

The sample standard deviation is:

S= √summation(x-xbar)²/ n-1

=√6/3= 1.4142

The degrees of freedom

df= N-1= 4-1= 3

For 95% confidence level, critical value of t

t= 3.182

The 95% confidence interval is:

=Xbar plus or minus t' *8/√n

= 10 plus or minus 3.182(1.4142/√4)

= 10plus or minus 2.25

So 7.75 or 12.25
