7. On Thursday, Kim purchased a medium iced caramel latte and a blueberry muffin for $5.18. Then, on Friday, Kim

sashaice [31]

Answer:

Cost of medium iced caramel latte = $3.59

Step-by-step explanation:

Assume;

Cost of medium iced caramel latte = x

Cost of blueberry muffin = y

So,

On Thursday

x + y = 5.18......eq1

On Friday

2x + 3y = 11.95.....eq2

Eq1 × 3

3x + 3y = 15.54......eq3

eq3 - eq2

x = 3.59

Cost of medium iced caramel latte = $3.59

A flat rectangular piece of aluminum has a perimeter of 70 inches. The length is 11 inches longer than the width. Find the width

rodikova [14]

perimeter = 2L +2w

L = w+11

70 = 2(w+11) +2w

70 = 2w+22+2w

70= 4w + 22

48 = 4w

w=48/4 = 12

width = 12

length = 12+11 = 23

2x12 = 24

2x23 = 46

46+24 = 40

length = 23 inches, width = 12 inches

During a rock concert, the noise level (in decibels) in front row seats has a mean of 92 dB with a standard deviation of 9 dg_ W

rodikova [14]

Answer:

The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.

Step-by-step explanation:

When we do not know the shape of the distribution, we use the Chebyshev's Theorem to find the minimum percentage of a measure within k standard deviations of the mean.

This percentage is:

$p = 1 - \frac{1}{k^{2}}$

Within 8 standard deviations of the mean

This means that $k = 8$ . So

$p = 1 - \frac{1}{8^{2}} = 1 - \frac{1}{64} = \frac{64 - 1}{64} = \frac{63}{64} = 0.9844$

The minimum percentage of noise level readings within 8 standard deviations of the mean is 98.44%.
