RUDIKE [14]2 years ago
8 0

Answer:

21 / 400

Step-by-step explanation:

Given 8 cherry, 5 grape, and 7 orange gummy vitamins out of the multivitamin container.

The probability that Julio will select an orange  multivitamin is

   7 ÷ 8 + 5 + 7 = 7/20

Also, given 11 berry, 3 lemon, and 6 pineapple  gummy vitamins out of the calcium container

The probability that Julio will select a lemon calcium is

3 ÷ 11 + 3 + 6 = 3/20

Therefore, since the event of selecting are independent of each other

probability that Julio will select an orange  multivitamin and a lemon calcium vitamin is

7/20 × 3/20

= 21 / 400

A park district is building an outdoor tennis court based on a scale drawing that measures 30cm long by 13.75 cm and uses the sc
Yuliya22 [10]

The actual area of the tennis court is 264 m²

First use the scale to find the actual dimensions of the court:

1 cm : 0.8m

30 cm in the drawing would be:

= 0.8 x 30

= 24 m outside

13.75cm in the drawing would be:

= 0.8 x 13.75

= 11 m outside

Area of a rectangle (which is what the dimensions resemble):

= Length x width

= 24 x 11

= 264 m²

In conclusion, the area of the tennis court is 264 m²

Max is trying to prove to his friend that two reflections, one across the x-axis and another across the y-axis, will not result
Mice21 [21]

Answer:

  Max is correct

  If one reflects a figure across the x-axis, the points of the image can be found using the pattern (x, y) ⇒ (x, –y).

  If one reflects a figure across the y-axis, the points of the image can be found using the pattern (x, y) ⇒ (–x, y).

  Taking the result from the first reflection (x, –y) and applying the second mapping rule will result in (–x, –y), not (y, x), which reflecting across the line should give.

Step-by-step explanation:

The answer above pretty well explains it.

The net result of the two reflections will be that any figure will retain its orientation (CW or CCW order of vertices). It is equivalent to a rotation by 180°. The single reflection across the line y=x will reverse the orientation (CW ⇔ CCW). They cannot be equivalent.
