Answer:
The probability the code is 14z is .
Step-by-step explanation:
Probability is calculated using the following fraction:
In this case, we are looking at three independent, combined events. This means that each pick of a number or letter does not depend on the previous event, but that the probability of each is linked, so we must multiply each probability together to get the total probability of the compete code. Since the numbers are 00 to 49, there are five total outcomes for the first number (0, 1, 2, 3, 4) and ten total outcomes for the second number (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The total outcomes for the letter selection would be 26, since there are 26 letters in the alphabet. Now, we multiply each probability together:
Answer:
$96
Step-by-step explanation:
$128 X 78/100
= $128 X .75
= $96

Answer: C
Step-by-step explanation:
Length = x+6
Width = 2(x+6)
Area = x+6*2x+12
= 2+72
Answer:
∠ 1 = 130°, ∠ 2 = 50°
Step-by-step explanation:
∠ 1 and 130° are alternate angles and congruent, so
∠ 1 = 130°
∠ 2 and 130° are same- side interior angles and are supplementary, so
∠ 2 + 130° = 180° ( subtract 130° from both sides )
∠ 2 = 50°
Answer:
1090sqr.inches
Step-by-step explanation:
The area of the arched-interior can be calculated by adding the value of the area of the semi circle to that of the rectangle.
The semi-circle has a diameter of 24 inches while the rectangle has a length of 36 inches.
The area of the semi circle is simply: πr^2/2
Since r = d/2, r here is 24/2 = 12
Area of semicircle is thus 22/7 * 12 * 12 * 1/2 = 226.2sqr.inches
The rectangle measures 24 inches by 36 inches. The area here is 24 * 36 = 864 sqr.inches
The total area is thus; 864 + 226.2 = 1090 sqr.inches
