Answer:
0.5 ; 0.34458
Step-by-step explanation:
Given that:
Mean (m) = 28
Standard deviation, s = 5
To obtain the Zscore :
Z = (x - m) / s
1.) P(x > 28)
Z = (28 - 28) / 5
Z = 0
P(Z > 0) = 0.5 (Z probability calculator)
2.) P(x < 26)
Z = (26 - 28) / 5
Z = - 0.4
P(Z > -0.4) = 0.34458 (Z probability calculator)
Answer:
1.1, 12, 99
Step-by-step explanation:
For the first one, we divide 2.5 by 2.2 (2.5/2.2) to get approximately 1.1 kilograms. So it would be the first option. For the second one, we know that 8x6=48, so we multiply 2 by 6 to get 12/48, so it would be the second option. For the third one, we can do this problem: 110/20 to get 5.5. We can multiply 18 by 5.5 to get 99. So that means the answer would be the first option.
Step-by-step explanation:
when to the nearest tenth the answer will be 25.80
7/20 converts to 35/100, so as a percent it is 35% and as a decimal it is .35.
