So there are 8 total cards, so you need to make your fraction out of 8. and there are 5 blue cards, so the probability of drawing one blue card is 5/8. but because you are doing a second draw, and NOT replacing the card you pulled the first time, you need to multiply 5/8 (the probability of drawing one blue card) and 4/7 (the second drawing).
5/8•4/7=5/14 which means the probability of drawing 2 blue cards in a row without replacing the first card is 5/14

Answer:192.0 inch
Step-by-step explanation:
V=1/3xArea of base x height
=1/3x (9x4)x16
=576/3
=192.0 inches
Answer:The coefficients are the numbers that multiply the variables or letters. Thus in 5x + y - 7, 5 is a coefficient. It is the coefficient in the term 5x. Also the term y can be thought of as 1y so 1 is also a coefficient.A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1. ... Example: In ax2 + bx + c, "x" is a variable, and "a" and "b" are coefficients.First of all, coefficent means the number standing in front of a variable.
So, according to the expression, 2 - 5x - 4 + 8, the coefficient is -5.
Why? because it stands in front of the variable.
Step-by-step explanation:
Use exponential law, we have
Answer:
288 in²
Step-by-step explanation:
The formula used to solve this question is :
Lateral Surface Area = s( P1 + P2)
Where s = slant height = 2 inches
P1 and P2 = Perimeter of the bases
Perimeter of base 1 = 4 × length of the end of the small square
4 × 17 inches = 68 inches
Perimeter of base 2 = 4 × length of the end of the large square
4 × 19 inches = 76 inches
Lateral Surface Area = 2 × (68 + 76)
= 2 × 144
= 288 in²
