Answer: 0.38
Step-by-step explanation:
Since the variable x is represented by a standard normal distribution, the probability of x > 0.3 will be calculated thus:
P(x > 0.3)
Then, we will use a standard normal table
P(z > 0.3)
= 1 - p(z < 0.3)
= 1 - 0.62
= 0.38
Therefore, p(x > 0.3) = 0.38
The probability of x > 0.3 is 0.38.
Answer:
-4r
Step-by-step explanation:
r + (-5r)
1r + (-5r)
Factor out an r
r( 1 -5)
One minus 5 is negative 4. If you have one dollar and you borrow five dollars, how much did you borrow? 4 but that 4 is borrowed so it is negative
r (-4)
-4r
Step-by-step explanation:
EF = 4x - 15
FG = 3x - 7
EG = EF + FG = 20
so,
4x - 15 + 3x - 7 = 20
7x - 22 = 20
7x = 42
x = 6
EF = 4×6 - 15 = 9
FG = 3×6 - 7 = 11
1 ft = 12 in.
4 ft = 4 * 1 ft = 4 * 12 in. = 48 in.
4 ft 7 in. = 48 in. + 7 in. = 55 in.
4 ft 7 in. < 56 in.
Answer:
8/35
Step-by-step explanation:
1 1/4 = 5/4
3 1/2 = 7/2
5/4 × 7/2
Find the reciprocal. (flip numerator and denomimator)
4/5 × 2/7 = 8/35
