Answer:

Interquartile Range= 0.079.

Step-by-step explanation:

Given,

The batting averages for seven baseball players are

0.176, 0.235, 0.272, 0.158, 0.201, 0.255, 0.303

First we have arrange the data in descending order or ascending order.

The ascending order of the data is

0.158, 0.176, 0.201, 0.235, 0.255, 0.272, 0.303

Median: The middle term of the data is the median of the data.

Here

Median = 0.235

First quartile: The median of the lower half of data.

The lower half of the data is 0.158, 0.176, 0.201

$Q_1=0.176$

Third quartile: The median of the upper half of data.

The upper half of the data is 0.201, 0.255, 0.303

$Q_3=0.255$

Interquartile: The difference between first quartile and third quartile.

Interquartile Range = $Q_3-Q_1$

=(0.255- 0.176)

=0.079

What is the true solution to the logarithmic equation?<br>log2 [log2(sqrt4x)]=1

erastova [34]

Answer:4

Step-by-step explanation:

log₂[log₂(√4x)] = 1

log₂2 =1

So we replace our 1 with log₂2

log₂[log₂(√4x)] = log₂2

log₂ on bothside will cancel each other.

We will be left with;

[log₂(√4x)] = 2

log = power of exponential

√4x = 2²

√4x = 4

Square bothside

(√4x)² = 4²

4X = 16

Divide bothside by 4

4x/4 = 16/4

x = 4

Vince has a rectangular rug in his room with an area of 10 ft the length of the rug is 18 inches longer than the width what coul

aev [14]

The length of the rug is 4 ft.

The width of the rug is 2.5 ft.

Explanation:

The area of the rug is 10 ft.

The length of the rug be l.

Let us convert the inches to feet.

Thus, $18 inches = 1.5 ft$

Thus, the length of the rug is $l=1.5+w$

Let the width of the rug be w.

Substituting these values in the formula of area of the rectangle, we get,

$A=length\times width$

$10=(1.5+w)(w)\\10=1.5w+w^2\\w^2+1.5w-10=0$

Solving the expression using the quadratic formula,

$w=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}$

Substituting the values, we have,

$$w=\frac{-15 \pm \sqrt{15^{2}-4 \cdot 10(-100)}}{2 \cdot 10}\\$

$w=\frac{-15 \pm \sqrt{4225}}{20}$

$w=\frac{-15 \pm 65}{2 0}$

Thus,

$w=\frac{-15 + 65}{2 0}\\w=\frac{50}{20} \\w=2.5$ and $w=\frac{-15 - 65}{2 0}\\w=\frac{-80}{20} \\w=-4$

Since, the value of w cannot be negative, the value of w is 2.5ft

Thus, the width of the rug is 2.5ft

Substituting $w=2.5$ in $l=1.5+w$ , we get,

$l=1.5+2.5\\l=4$

Thus, the length of the rug is 4 ft.
