Mathematics
1 answer:
laila [671]3 years ago

Answer:

1.\ \ \frac{x}{24}

Step-by-step explanation:

1. let x be the unknown number.

-Given that 24 divided by x is less than x is less than 7 means that 7 is greater than the quotient thereof.

-The in equality is written as:

\frac{x}{24}

2.Let the amount Chris has be y.

-At most is a term of inclusivity implying less than or equal to a specified quantity.

-$5 less than twice y will therefore be represented as:

2y-5\leq 124

3. It is clear that the minimum age to have a drivers license is 16.

-Let x be the age of a driver whose age is unknown.

-It is therefore obvious that all drivers in Ohio are either exactly 16 years or older.

-Our inequality symbol is that of equal to or greater than, thus:

x\geq 16

4. let x be the number of CD's bought and y of DVD's bought.

-CD's are priced at $14 each and DVD's at $16 each, given a budget of $65.

-They can only buy a number of units whose price is less than or exactly $65, thus:

14x+16y\leq 65

(05.01)Which equation can be used to calculate the area of the shaded triangle in the figure below?
Marina86 [1]

Equation of shaded triangle is \frac{1}{2} (14\times8).

Solution:

Length of the rectangle = 14 ft

Breadth of the rectangle = 8 ft

Area of the rectangle = length × breadth

                                    = 14 × 8

In this rectangle the diagonal splits the rectangle into two equal halves.

Area of the shaded triangle = Half of area of rectangle

                                              $=\frac{1}{2} (14\times8)

Area of the shaded triangle = \frac{1}{2} (14\times8)

Hence the equation can be used to calculate the area of the shaded

triangle is \frac{1}{2} (14\times8).

Suppose a random sample of 25 students is selected from a community college where the scores in the final exam (out of 125 point
BartSMP [9]

Answer:

he probability that the sample mean deviates from the population mean = 112 by no more than 4= 0.9050

Step-by-step explanation:

mean = 112

sd = 12/sqrt(25) = 2.4

z = (x - μ)/σ

z = (116 - 112)/2.4 = 1.67

Therefore,

P(X >= 116) = P(z <= (116 - 112)/2.4)

= P(z >= 1.67)

= 1 - 0.9525

= 0.0475

z = (x - μ)/σ

z1 = (108 - 112)/2.4 = -1.67

z2 = (116 - 112)/2.4 = 1.67

Therefore, we get

P(108 <= X <= 116) = P((116 - 112)/2.4) <= z <= (116 - 112)/2.4)

= P(-1.67 <= z <= 1.67) = P(z <= 1.67) - P(z <= -1.67)

= 0.9525 - 0.0475

= 0.9050

What is the interquartile range of the sequence 5,5,8,8,13,14,16,16,19,22,23,27,31 ?
Romashka-Z-Leto [24]

Answer:

The Interquartile range is 10.

Step-by-step explanation:

First, we will need to find the mean, the mean of this sequence is 16, you will now need to find quartile 1 and quartile 3. Quartile 1 is 13, and quartile 3 is 23. Lastly, subtract Quartile 3 and Quartile 1 will be the answer.

So, 23-13=10

The Answer will be 10, the interquartile range is 10.

Hope this helps!
