$\huge \boxed{\mathbb{QUESTION} \downarrow}$

Which of the following is not a linear equation in one variable?

a) 33

b) 33(x+y)

c) 33x

d) 33y

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Option <em><u>b) 33 (x + y)</u></em> is not a linear equation in 1 variable.
Here, we can see that there are 2 variables used ⇨ x & y. Hence, even though it's a linear equation, it's not in 1 variable.
All the other options are in 1 variable or don't have a variable at all.

zhenek [66]

Question:

If a sample of 2 hammer is selected

(a) find the probability that all in the sample are defective.

(b) find the probability that none in the sample are defective.

Answer:

a $Pr = \frac{2}{110}$

b $Pr = \frac{72}{110}$

Step-by-step explanation:

Given

$n = 11$ --- hammers

$r = 2$ --- selection

This will be treated as selection without replacement. So, 1 will be subtracted from subsequent probabilities

Solving (a): Probability that both selection are defective.

For two selections, the probability that all are defective is:

$Pr = P(D) * P(D)$

$Pr = \frac{2}{11} * \frac{2-1}{11-1}$

$Pr = \frac{2}{11} * \frac{1}{10}$

$Pr = \frac{2}{110}$

Solving (b): Probability that none are defective.

The probability that a selection is not defective is:

$P(D') = \frac{9}{11}$

For two selections, the probability that all are not defective is:

$Pr = P(D') * P(D')$

$Pr = \frac{9}{11} * \frac{9-1}{11-1}$

$Pr = \frac{9}{11} * \frac{8}{10}$

$Pr = \frac{72}{110}$

balu736 [363]

Answer:

French test

Step-by-step explanation:

We first calculate the scores as percentages:

#Spanish test:

$=\frac{score}{total}\times 100\%\\\\\\=\frac{27}{32}\times 100\%\\\\=84.38\%$

#For the French test, her percentage is:

$=\frac{score}{total}\times 100\%\\\\=\frac{19}{21}\times 100\%\\\\=90.48\%$

Since, 90.48$>84.38%, Claire did better in the French test.

Find the image of A(6, -4) after it is reflected over the line y = - 2, then reflected over the line x = 1. (-4, 6) (-4, 0) (-4,

olchik [2.2K]

Answer:(-4,0)

Step-by-step explanation:

Given

Point A (6,-4)

Reflection of Point A about line y=-2 is

A' (6,0)

If any Point is reflected about any line y=constant then its x coordinate remains same

Now reflection of Point A' about x=1 is

A'' (-4,0)

If any point is reflected about line x=constant then its y coordinate remains same
