A realtor earns a 3.25% commission

Mathematics
1 answer:
dlinn [17]3 years ago
6 0

Since the commission is 3.25%, we simply multiply this fraction in decimal form by x, since it will equal 10566.40:

0.0325*x=10566.40

Divide both sides by 0.0325:

x = 10566.40/0.0325

x = 325120

<u>The house sold for $325,120</u>

I NEED HELP PLSSS , what is the volume and surface area
GaryK [48]

Given:

The dimensions of the given cuboid are 8 in, 6 in and 7 in.

To find:

The volume and the surface area of the given cuboid.

Solution:

The volume of cuboid is:

V=l\times b\times h

Where, l is length, b is breadth and h is height.

V=8\times 6\times 7

V=336

Therefore, the volume of the cuboid is 336 cubic inches.

The surface area of the cuboid is:

A=2(lb+bh+hl)

Where, l is length, b is breadth and h is height.

A=2(8\times 6+6\times 7+7\times 8)

A=2(48+42+56)

A=2(146)

A=292

Therefore, the surface area of the cuboid is 292 square inches.

Natali5045456 [20]

Answer:

Zach time of reading every weekend forms a sequence with these terms: 10, 20, 40, 80. On the other hand, that of Victoria forms a sequence with terms: 35, 50, 65, 80. By keenly observing the sequences, Zach's sequence is a geometric sequence with a common ratio equal to 2 and Victoria's sequence is an arithmetic or linear sequence with a common difference of 15. Thus, the answer is letter B.

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical ru
Harlamova29_29 [7]

Answer:

1.35%

Step-by-step explanation:

Suppose that IQ scores have a bell-shaped distribution with a mean of 104 and a standard deviation of 15. Using the empirical rule, what ? Please do not round your answer.

Empirical rule formula states that:

95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

We don't know the number of Standard deviation yet , hence:

Mean = 104

Standard deviation = 15.

At least 59

Hence:

104 - 15x = 59

104 - 59 = 15x

45 = 15x

x = 45/15

x = 3

Hence, At least 59 is 3 standard deviations away from the mean on one side of the distribution thus,

99.7% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ .

100% - 99.7%

= 0.003

Since it is on one side of the distribution:

= 1.5% - 0.3%

= 0.015 - 0.0015

= 0.00135

Converting to percentage

= 1.35%

The percentage of IQ scores that are at least 59 is 1.35%
