Write the equation in standard form using integers: y = -2/5x - 3

1 answer:

7 0

Let's assume you meant y = (-2/5)x - 3.

-2/5x could be misinterpreted.

First, clear out the fraction(s). To do this, mult. both sides of the above eq'n by 5.

Result: 5y= -2x - 15. Add 2x to both sides. The resulting equation is what you wanted: an equation in the form Ax + By = C (standard form).

A machine used for packaging seedless golden raisins is set so that their standard deviation in the weight of raisins packaged p

Kazeer [188]

Answer:

population standard deviation does not differ from 0.25

Step-by-step explanation:

The hypothesis :

σ² = 0.25²

σ² ≠ 0.25²

The Chisquare statistic, χ²: (n-1)*s²/σ²

Where s² = sample variance ; sample size, n = 30

Using calculator, the sample variance, s² = 0.1646

χ² = (n-1)*s²/σ²

χ²: (30 - 1) * 0.1646 / 0.25²

χ² = (29 * 0.1646) / 0.0625

χ² = 0.3292 / 0.0625

χ² = 5.2672

α = 0.05

Using the Pvalue from Chisquare calculator ; df = 29

Pvalue = 1

Since, Pvalue > α ; We fail to reject the null and conclude that population standard deviation does not differ from 0.25

Two points located on jk are j (-1,-9) and k (5,3). What is the slope of jk?

Ivenika [448]

Answer:

Step-by-step explanation:

slope of line= $\frac{y1 - y2}{x1 - x2}$

slope of JK

$= \frac{3 - ( - 9)}{5 - ( - 1)} \\ = \frac{3 + 9}{5 + 1} \\ = \frac{12}{6} \\ = 2$
