Whats an approximate equation of a line that passes through the points (-4.3,2.3) and (1.3,-7.4)
Wewaii [24]
Use the 2 points to find the gradient of the line
Gradient = (y - y1)/(x - x1), y and y1 are the two different y values.
(2.3 - - 7.4)/(-4.3 - 1.3) = -97/56 = -1.732
Note: y and x both come from the same coordinate, and y1 and x1 also come from the same coordinates - (x , y), (x1 , y1)

Use the following to find the equation (x, x1, y, and y1 are not the same as the first part)
y - y1 = m(x - x1)

Where x2 and y2 is an intersection (one of the coordinates you used) and m is the gradient you found.
So...
y - 2.3 = -1.732(x - - 4.3)
You can simplify this if you are required to.

How much material was required for each dresses of the same size if it took 5 1/2 yards for both ?
ki77a [65]

Answer:

2.75 yards

Step-by-step explanation:

If it took both (meaning 2) dresses a certain amount, half of that amount is one dress. So, we need to divide 5 1/2 by 2

*1/2 of 1 = 0.5

0.5 + 5 = 5.5

5.5 / 2 = 2.75

(2.75 also equals 2 3/4)

Suppose a university advertises that its average class size is 34 or less. A student organization is concerned that budget cuts
Korolek [52]

Answer:

H0​: μ ≤ 34

H1​: μ > 34

The​ z-test statistic is ≈ 1.8

The critical​ z-score is 1.28

we fail to reject the null hypothesis H0​: μ ≤ 34

Step-by-step explanation:

H0​: μ ≤ 34

H1​: μ > 34

The​ z-test statistic is calculated using the formula:

z=\frac{X-M}{s} where

  • X is the average class size found in the sample (35.6)
  • M is the mean according to the null hypothesis (34)
  • s is the standard deviation for class size (9)

then z= \frac{35.6-34}{9} ≈ 0.18

The critical​ z-score is 1.28 for α=0.10​ (one tailed)

Because the test statistic is less than the critical value, do not reject the null hypothesis.
