Step-by-step explanation:
brackets means multiply hence -x×3y×-2x
Answer:
pretty sure its 25%
Step-by-step explanation:
1/4 is the same as 0.25 which is also the same as 25%
0.25 is a demimal
the one to the right of that is a ratio
the one under that is equivalent fractions
the one the right of equivalent fractions is simplest form
1/3−1/2=− -1/6
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1....Complete the multiplication and the equation becomes ....The two fractions now have like denominators so you can subtract the numerators. This fraction cannot be reduced.....and that's how i got the answer
Answer:
33.2%
Step-by-step explanation:
Calculate the z-scores.
z = (x − μ) / σ
z₁ = (82 − 100) / 15
z₁ = -1.2
z₂ = (98 − 100) / 15
z₂ = -0.133
Use a chart or calculate to find the probability.
P(-1.2 < Z < -0.133) = P(Z < -0.133) − P(Z < -1.2)
P(-1.2 < Z < -0.133) = 0.4470 − 0.1151
P(-1.2 < Z < -0.133) = 0.3319
Rounded to the nearest tenth, the percentage is 33.2%.
