In the xy-plane,

Increase in x-value move the point right and decrease in x-value move the point left

Increase in y-value move the point up and decrease in y-value move the point down.

So, the translation of the point (x, y) to (x - 1, y + 3) would be one unit along x-axis to the left and 3 units along y-axis up.

In a batch of 100 parts, 40 are red, 50 are L-shaped and 22 are both red and L-shaped. What is probability that a part picked fr

Bogdan [553]

The probability that a part picked from this batch at random is either red or L-shaped is 0.68

Step-by-step explanation:

Let us revise some rules of probability

The addition rules are:

P(A or B) = P(A) + P(B) ⇒ mutually exclusive (events cannot happen at the same time)
P(A or B) = P(A) + P(B) - P(A and B) ⇒ non-mutually exclusive (if they have at least one outcome in common)

∵ A batch has 100 parts

∵ 40 are red

- Probability of an event is the [even occurs/total outcomes]

∴ P(red) = $\frac{40}{100}=0.4$

∵ 50 are L-shaped

∴ P(L-shaped) = $\frac{50}{100}=0.5$

∵ 22 are both red and L-shaped

∴ P(red and L-shaped) = $\frac{22}{100}=0.22$

This is non-mutually exclusive because there is a common between them, so we will use the 2nd rule

∵ P(red or L-shaped) = P(red) + P(L-shaped) - P(red and L-shaped)

∴ P(red or L-shaped) = 0.4 + 0.5 - 0.22

∴ P(red or L-shaped) = 0.68

The probability that a part picked from this batch at random is either red or L-shaped is 0.68

Is (0,0) a solution to this system?

Anuta_ua [19.1K]

Answer:

option-B

Step-by-step explanation:

we are given system of inequality as

$y\leq x^2-4$

$y>2x-1$

now, we can check solution

At (0,0):

we can plug x=0 and y=0

and check inequality

$0\leq 0^2-4$

$0\leq -4$

so, this is FALSE

now, we can check second inequality

$0>2\times 0-1$

$0>-1$

So, this is TRUE

so, option-B

Brut [27]

Weight in Robbie backpack is $\frac{27}{6}$ pounds or 4.5 pounds

Solution:

Given that Today Robbie is carrying his history textbook and his lunch in his backpack.

To find: weight in Robbie's backpack

From given,

Weight of history book = $2\frac{5}{6}$ pounds

Weight of lunch = $1\frac{2}{3}$ pounds

weight in Robbie's backpack = Weight of history book + Weight of lunch

$\rightarrow 2\frac{5}{6} + 1\frac{2}{3}$

Convert the mixed fractions

$\rightarrow \frac{6 \times 2 + 5}{6} + \frac{3 \times 1 + 2}{3}\\\\\rightarrow \frac{17}{6} + \frac{5}{3}\\\\\rightarrow \frac{17+10}{6}\\\\\rightarrow \frac{27}{6}$

Thus weight in Robbie backpack is $\frac{27}{6}$ pounds or 4.5 pounds
