Answer:Answer is 4

Step-by-step explanation:

Because the standard equation is;

y=mx + c

By comparing both the equations we can get y-intercept.

Answer:

b = 4

Step-by-step explanation:

y = mx + b represents the equation of a line

m represents the slope

b represents the y-intercept

Based on what we're given, we could determine that 4 is our y-intercept or b.

The slope is the coefficient of the variable. In this case, -1/4 is before the x. So the answer is C

lab scale known to have a standard deviation of 0.001gram, speimen weghtted 8 times. average weiht is 4.1602 gram. what is 99% c

gtnhenbr [62]

Answer:

$99\% CI=4.1602 \pm 0.0009$

Step-by-step explanation:

From the question we are told that:

Sample size $n=8$

Mean $\=x=4.1602$

Standard deviation $\sigma=0.001gram$

Generally 99\% confidence from table is mathematically given by

$99\% CI=4.1602 \pm *2.576*\frac{0.001}{\sqrt{{8}}}$

$P(-z$

$Z_{\alpha/2}=2.576$

Generally the equation for 99\% confidence level (CI) is mathematically given by

$99\% CI=\=x \pm Z_{\alpha/2*\frac{\sigma}{\sqrt{{n}}}$

$99\% CI=4.1602 \pm 0.0009$

For a shape to be a square all the angles need to be 90 degrees.

Angle B = 3x+60 = 90

3x +60 = 90

Subtract 60 from each side:

3x = 30

Divide both sides by 3:
x = 30 /3
X = 10
