BaLLatris [955]3 years ago
5 0

Answer:

15.9

Step-by-step explanation:

Formula:

a² + b² = c²

6² + x² = 17²

36 + x² = 289

x² = 253

\sqrt{x^2} =\sqrt{253}

x = 15.91

The width of a rectangle is unknown the length of the rectangle is two more units than it's with what is simple find elderberry
disa [49]

Answer:

Therefore,

The area of the rectangle in terms of width

Area=W^{2}+2W

Step-by-step explanation:

Let the Width of rectangle be 'W' inches.

The length of a rectangle be 'L' inches.

According to the given condition,

Length = 2 + Width

L = W + 2

To Find:

Area of Rectangle in terms of Width = ?

Solution:

We have area of rectangle given as

\textrm{Area of Rectangle}=Length\times Width

Substituting the values we get

Area=(W+2)\times W

Applying Distributive property A(B+C)=AB+ACwe get

Area=W^{2}+2W        .......As required

Therefore,

The area of the rectangle in terms of width

Area=W^{2}+2W

A toy manufacturer wants to know how many new toys children buy each year. A sample of 601 children was taken to study their pur
Lilit [14]

Answer:

The confidence interval is 6.6<μ<6.8.

Step-by-step explanation:

We have:

Number of observations = 601

Mean = 6.7

Standard deviation σ = 1.5

The z-score for a 95% confidence interval is 1.96.

The limits of the confidence interval can be calculated as

X \pm z*\frac{\sigma}{\sqrt{n}}\\\\LL=X-z*\frac{\sigma}{\sqrt{n}}=6.7-1.96*\frac{1.5}{\sqrt{601} } =6.7-0.1199=6.6\\\\UL=X+z*\frac{\sigma}{\sqrt{n}}=6.7+1.96*\frac{1.5}{\sqrt{601} } =6.7+0.1199=6.8

The confidence interval is 6.6<μ<6.8.

If you remove the last digit (one’s place) from a 4-digit whole number, the resulting number is a factor of the 4-digit number.
shutvik [7]

Answer:

  900

Step-by-step explanation:

We assume that your 4-digit number must be in the range 1000 to 9999. Clearly, any number ending in zero will meet your requirement:

  1000/100 = 10

  3890/389 = 10

However, the requirement cannot be met when the 1s digit is other than zero.

__

For some 3-digit number N and some 1s digit x, the 4-digit number will be

  4-digit number: 10N+x

Dividing this by N will give ...

  (10N+x)/N = 10 remainder x

N will only be a factor of 10N+x when x=0.

So, there are 900 4-digit numbers that meet your requirement. They range from 1000 to 9990.
