Hello!

X and Y intercepts are found when graphing an equation. You know the X and Y intercepts by when a point crosses the X axis, and for the Y intercept, when a point crosses the Y axis.

First off we must simplify the equation.

4y + 12 = -2x - 12

Here is the photo of the graph attached.

By looking at the graph we can see the answer is...

X intercept = (-12,0)
Y intercept = (0,-6)

It costs more to produce defective items - since they must be scrapped or reworked - than it does to produce non-defective items

ale4655 [162]

Answer: a) 1082, b) wider.

Step-by-step explanation:

Since we have given that

Margin of error = 0.1 millimeter = E

Standard deviation = 2 mm = σ

Critical value would be

$z_{\frac{\alpha}{2}}=z_{0.05}=1.645$

a) Sample size would be

$n=(\dfrac{z_{\frac{\alpha }{2}}\times \sigma}{E})^2\\\\n=(\dfrac{1.645\times 2}{1})^2\\\\n=1082.41\\\\n=1082$

b) Sample size, n = 100

So, the margin of error would be

$E=z_{\frac{\alpha }{2}}\times \dfrac{\sigma}{\sqrt{n}}\\\\E=1.645\times \dfrac{2}{\sqrt{100}}\\\\E=1.645\times \dfrac{2}{10}\\\\E=0.329$

Since the margin of error in b part is more than a part, as we know that the higher the margin of error, the wider the confidence interval.

So, it would have wider confidence interval.

Hence, a) 1082, b) wider.

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

This is a equilateral triangle
So all sides and angles are equal

Let one angle=x

${:}\longrightarrow$ $\sf x+x+x=180$

${:}\longrightarrow$ $\sf 3x=180$

${:}\longrightarrow$ $\sf x={\dfrac {180}{3}}$

${:}\longrightarrow$ $\sf x=60°$

Jack used 1 2 of a bag of okra to make 1 4 of a gallon of jambalaya. If Jack's recipe is for 1 gallon of jambalaya, how much okr

Solnce55 [7]

Answer:

4 bags of okra

Step-by-step explanation:

To find the unit rate: multiply the numerator by the reciprocal of the denominator.

unit rate =

1/2 divided by 1/4

= 1/2× 4/1

=4/2

= 2 bags per gallon

Therefore, double the recipe: 2 × 2 = 4 bags of okra
