Answer:

x<13

Step-by-step explanation:

To solve this, we want to have the isolate the variable x on the left side, by itself without a coefficient. All we have to do to do this is add 4 to both sides, cancelling out the -4 and getting x<13

Answer:

x = 13 + y

Step-by-step explanation:

Simplify:

-4 + x = y + 9

Reorder the terms:

-4 + x = 9 + y

Move all terms containing x to the left all other terms to the right

Add 4 to each side of the equation

-4 + 4 + x = 9 + 4 + y

Combine like terms: -4 + 4 = 0

0 + x = 9 + 4 + y

x = 9 + 4 + y

9 + 4 = 13x = 13 + y

Answer:

x = 13 + y

rodikova [14]

Answer:

(5r - 20)

Step-by-step explanation:

(3r + 14) + (Ar + B) = (8r - 6)

B = -6 - 14 = -20

Please help!!!!<br><br>CE is tangent to this circle, CD is a radius and ECB=48 what is BAC

den301095 [7]

Answer:

48degrees

Step-by-step explanation:

From the circle geometry shown, traingle BDC is an isosceles triangle which shows means that their base angels are the same. Hence;

<B = <C

<CBD + <BCD + <D = 180

<BCD + <BCD + <D =180

2<BCD + <BDC = 180

Get <BCD;

<BCD+ <ECB = 90

<BCD + 48 = 90

<BCD = 90 - 48

<BCD = 42degrees

Get <BDC

2<BCD + <BDC = 180

2(42)+ <BDC = 180

84 + <BDC = 180

<BDC = 180 - 84

<BDC = 96

Since angle at the centre is twice that at the circumference, then;

<BAC = 1/2(<BDC )

<BAC = 96/2

<BAC = 48degrees

The mean square for error in the ANOVA provides an estimate of the variance of an individual treatment average.

What is a variance?

Variance is the anticipated squared variation of a random variable from its population mean or sample mean in probability theory and statistics. Variance serves as a proxy for dispersion, or the degree to which a set of numbers deviates from their mean.

Here, We have

The mean square for error in the ANOVA provides an estimate

ANOVA = Analysis of VarianceThe correct answer is (B)

The mean square for error (MSE) in the analysis of variance (ANOVA) provides an estimate of the variance of an individual treatment average.

Unlike option C which refers to an individual observation,

option B refers to a group of observations that are classified into a single treatment sample.

The MSE measures (gives an estimate of) the variation within this treatment sample. In this case, the variation is in the average or the mean. This could be average texture, average strength, average penetration, etc.

Hence, the mean square for error in the ANOVA provides an estimate of the variance of an individual treatment average.
