A data set has a normal distribution with a mean at 47 and a standard deviation of 4.6 use this information to scale the horizontal axis with the mean at this distribution and values at 1, 2, and 3 standard deviations above and below the mean

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x

the answer is 8/21

hope this

answer: i feel you honey.

step-by-step explanation:

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
