Answer:

The largest possible number is 24, the smallest possible number is -6.

Step-by-step explanation:

maths

Smaller possible number = -6 and larger possible number = 24.

The absolute value of a number is the distance value from zero without considering the sign of a number. It is also represented as |x|, where x is any number.

Given:

The distance between two numbers on the number line is 15.

And the distance between the numbers is the absolute value.

And one of the numbers is 9.

Let x and -x are the numbers.

So, when the number is x,

distance,

x-9 = 15.

x = 24

And when the number is -x,

distance,

9 -(-x)= 15.

x = -6.

Therefore, the possible integers are -6 and 24.

Answer:

my names jeff

Step-by-step explanation:

Answer:

Step-by-step explanation:

So its a rectangle which means it has 4 sides

two of the sides are x feet long

and two of them are 2x -3 feet long

we also know that all of the sides together are 48 feet long

so the equation would look like

2(x)+2(2x-3)=48

or x+x+2x-3+2x-3=48

It doesn't matter which one you use because they both simplify to

6x-6=48

add 6 to both sides

6x=54

divide both sides by 4

x=9

Answer: y = 14^x

Step-by-step explanation:

Here the options are:

a y = 14^x

b y = -3*(17)^x

c y = 120x

d y = -275x

to see which function increases the fastest (or which function is steeper) we need to look at the first derivations of each one of these, and see which one is larger for every value of x:

the derivations are:

a y = x*14^(x - 1)

b y = -x*3*(17)^(x  - 1)

c y = 120

d y = -275

So we can already discard options c and d, because have constant rate of change.

Then we keep options a and b.

Always when we have an exponential function, like a^x and b^x

The one with the larger base will be steeper.

So if a > b, then:

a^x is steeper than b^x

In this case, the function:

y = -3*(17)^x

has a larger base, but, this function is negative.

This means that as x increases, our function will decrease, then this function will not "increase the fastest" (because it does not increase)

Then the left option (a: y = 14^x)

Will be the correct one.

(this will happen after some value of x, because two of the options have constant derivatives, these may be steeper for smaller values of x, and as x increases, we will see that y = 14^x is the one that increases the fastest)

D. Marie can make 60 pies.

Step-by-step explanation:

In this problem, we know that amount of small mango pies is directly proportional to the amount of mangoes. The amount needed for preparing an amount of pies is calculated by simple rule of three:

A. Marie can make 30 pies.

[tex]x = \frac{10\,mangoes}{12\,pies}\times 30\,pies[/tex]

[tex]x = 25\,mangoes[/tex]

25 mangoes are required for producing 30 pies.

B. Marie can make 40 pies.

[tex]x = \frac{10\,mangoes}{12\,pies}\times 40\,pies[/tex]

[tex]x = 33.333\,mangoes[/tex]

34 mangoes are required for producing 40 pies.

C. Marie can make 50 pies.

[tex]x = \frac{10\,mangoes}{12\,pies}\times 50\,pies[/tex]

[tex]x = 41.667\,mangoes[/tex]

42 mangoes are required for producing 50 pies.

D. Marie can make 60 pies.

[tex]x= \frac{10\,mangoes}{12\,pies}\times 60\,pies[/tex]

[tex]x = 50\,mangoes[/tex]

50 mangoes are required for producing 60 pies.

The complete statement is: Marie can make 12 small mango pies for every 10 mangoes.How many pies can she make with 50 mangoes.

Hence, correct answer is D.

57 pisquets

Step-by-step explanation:

Ratio of pisquets:vreels = 10:7

Ratio on Frank's rew farm: x:40

since ratios are equivalent, you'd so the same on both sides. To get from 7 to 40 u multiply by a number, so to get from 10 to x u have to multiply by that same number. To find this number, divide 40 by 7: 40/7 = 5.7

Then, multiply this by 10: 5.7 x 10 = 57

there are roughly 57 pisquets on his farm.

Answer:

60 cm^3

Step-by-step explanation:

The computation of the volume of the cuboid is given below:

let us assume the length be l

and b the breadth

So

l = b + 1

And, the perimeter is

2(l + b) = 18

2l + 2b = 18

2b + 2 + 2b = 18

b = 4

And l = 5

Now

2(l + b) × h = 54

2(5 + 4 ) × h = 54

h = 3

Now the volume of the cuboid is

= l × b × h

= 5 × 4 × 3

= 60 cm^3

Answer:

0.1373 = 13.73% probability that the lines are occupied for exactly 5 calls

Step-by-step explanation:

For each call, there are only two possible outcomes. Either the lines are occupied, or they are not. The events that the lines are occupied on successive calls are independent. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

The phone lines to an airline reservation system are occupied 61% of the time.

This means that [tex]p = 0.61[/tex]

If 11 calls are placed, what is the probability that the lines are occupied for exactly 5 calls

This is P(X = 5) when n = 11. So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 5) = C_{11,5}.(0.61)^{5}.(0.39)^{6} = 0.1373[/tex]

0.1373 = 13.73% probability that the lines are occupied for exactly 5 calls
