Answer:

Option A - (-5,-8) ordered pair is the reflection of (5,−8) across the the y-axis.

Step-by-step explanation:

To find : What ordered pair is the reflection of (5,−8) across the x-axis and the y-axis?

Solution :

Reflection across x-axis - the x value stay the same and y value changes sign i.e. (x,y)→(x,-y).

So, (5,-8)→(5,8)

Reflection across y-axis - the y value stay the same and x value changes sign i.e. (x,y)→(-x,y).

So, (5,-8)→(-5,-8)

Therefore, option A - (-5,-8) ordered pair is the reflection of (5,−8) across the the y-axis.

If a couple were planning to have three children, the sample space summarizing the gender outcomes would be: bbb, bbg, bgb,

MaRussiya [10]

There are two choices for each child: overweight (o) or underweight (u). So if the first child is o the next can be o or u. If the first is u the second can be o or u. This gives four possibilities. Here the first child is the letter noted first and the second is the one listed second:
OO
OU
UO
UU

There are 4 outcomes and if each is equally likely then the probability of each is 1/4. Thus the probability of UU is 1/4

The probability of one underweight and one over weight is 1/2 because in two of the outcomes listed above there is one O and one U (namely OU and UO). Since there are 4 outcomes the probability is 2/4 = 1/2

George buys some first class and second class stamps to put on some letters. Each first class stamp costs 67p, and each second c

Dafna1 [17]

Answer:

£191.36

Step-by-step explanation:

Sum the parts of the ratio, 1 + 4 = 5 parts

Divide 320 by 5 to find the value of one part of the ratio.

320 ÷ 5 = 64 ← value of 1 part of the ratio , thus

4 parts = 4 × 64 = 256

Thus he bought 64 first class and 256 second class.

Cost = (64 × £0.67) + (256 × £0.58)

= £42.88 + 148.48

= £191.36

Answer:

d = 3√10 ≈ 9.487

Step-by-step explanation:

The distance formula is appropriate.

d = √((x2 -x1)^2 +(y2 -y1)^2)

d = √((-3 -0)^2 +(2 -(-7))^2) = √(9 +81) = √90

d = 3√10
