The range, in mathematical terms, is only the y-values. So, what does this tell you? It tells you to focus on the y-values (The y values fall on the the vertical line/the line going up in down.). Now add the word function at the end. Range of the function. Translation = Y-values of the function.

According to the picture attachment, the line (in the terms of the y values only) starts at 0 and ends directly at 8, therefore the answer is A.

Mac's hotel had 128 rooms,and 25% of the rooms in the hotel did not have an ocean view

nata0808 [166]

The answer is 32 rooms did not have an ocean view.

25% = 1/4
( the word of is a keyword that the operation will be multiplication :) )
Knowing this information, the problem is askong 25% times 128.
1/4 x 128= 32
Hope I helped! ♡

the dimensions of a smaller rectangle are 3ft by 9ft the dimensions of a larger rectangle are 5ft by 15ft find the ratio of the

Alexxandr [17]

The ratio of the area of the smaller rectangle to the area of the larger

rectangle is $\frac{9}{25}$

Step-by-step explanation:

The formula of the area of a rectangle is A = l × w, where l and w

are its dimensions

The dimensions of a smaller rectangle are 3 ft by 9 ft
The dimensions of a larger rectangle are 5 ft by 15 ft

We want to find the ratio of the area of the smaller rectangle to

the area of the larger rectangle

∵ The dimensions of the smaller rectangle are 3 ft and 9 ft

∴ The area of the smaller rectangle = 3 × 9 = 27 feet²

∵ The dimensions of the larger rectangle are 5 ft and 15 ft

∴ The area of the smaller rectangle = 5 × 15 = 75 feet²

Let us find the ratio of the area of the smaller rectangle to the area

of the larger rectangle

→ smaller rectangle : larger rectangle

→ 27 : 75

Divide the both terms of the ratio by 3

→ 9 : 25

The two terms of the ratio do not divisible by any other number

∴ The simplest form of the ratio is 9 : 25

∴ The ratio of the area of the smaller rectangle to the area of the larger

rectangle = $\frac{9}{25}$

The ratio of the area of the smaller rectangle to the area of the larger

rectangle is $\frac{9}{25}$

The mean of a set of data is -3.82 and its standard deviation is 2.31. Find the z score for a value of 3.99.

gtnhenbr [62]

Answer:

The z- score for a value of 3.99 will be 3.38.

Step-by-step explanation:

It is given that the mean of a set of data is -3.82 and its standard deviation is 2.31.

Thus, the value of the z-score= $\frac{value-mean}{standarddeviation}$

= $\frac{3.99-(-3.82)}{2.31}$

= $\frac{3.99+3.82}{2.31}$

= $\frac{7.81}{2.31}$

= $3.38$

Thus, the z- score for a value of 3.99 will be 3.38.

Work out 5/8−2/5 Give your answer in its simplest form.

Inessa05 [86]

$\frac{5}{8} - \frac{2}{5}$

First, find the LCD (least common denominator) of the two fractions.
List the multiples of each denominator and find the one that is common.
Multiples of 8: 8, 16, 24, 32, 40
Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40
40 is your LCD.

Second, what can you divide by to make the denominators of each fraction '40'? Whatever you do to the bottom you must do to the top.
$\frac{5*5}{8*5} - \frac{2*8}{5*8}$

Third, multiply.
$\frac{25}{40} - \frac{16}{40}$

Fourth, since the denominators are the same now, we can combine them.
$\frac{25-16}{40}$

Fifth, subtract '25 - 16' to get 9.
$\frac{9}{40}$

Since $\frac{9}{40}$ is already in the simplest form, it is your answer.

Answer as fraction: $\frac{9}{40}$
Answer as decimal: $0.225$

How much further up the wall does the ladder in figure 2 reach than

ASHA 777 [7]

The ladder in figure 2 reaches 3.2 feet further up than the ladder in figure 1.

Step-by-step explanation:

Step 1:

In both the given figures, the ladder, the wall and the floor form a right-angled triangle. The floor is the adjacent side, the wall is the opposite side and the ladder is the hypotenuse.

According to the Pythagorean theorem,

$a^{2}+b^{2}=c^{2}$ , where c is the length of the hypotenuse while a and b are the lengths of the other two sides.

Step 2:

For the ladder in figure 1, assume the distance from the floor to the ladder's top is x feet. So a = x, b = 8 and c = 10 (hypotenuse).

$a^{2}+b^{2}=c^{2}$ , $x^{2}+8^{2}=10^{2}$ , $x^{2}=100-64=36, x=\sqrt{36}=6 \text { feet }$ .

So the distance between the floor and the ladder's top is 6 feet.

Step 3:

For the ladder in figure 2, assume the distance between the floor and the ladder's top is y feet. So a = y, b = 4 and c = 10 (hypotenuse).

$a^{2}+b^{2}=c^{2}$ , $y^{2}+4^{2}=10^{2}$ , $y^{2}=100-16=48, x=\sqrt{84}=9.1651 \text { feet }$ .

So the distance between the floor and the ladder's top is 9.1651 feet.

Step 4:

The difference in heights = The wall height in figure 2 - the wall height in figure 1.

The difference in heights = 9.1651 feet - 6 feet = 3.1651 feet.

Rounding this off to the nearest tenth of a foot, we get 3.2 feet.
