7.78, 7.8, 6.969, 7.7081 order these numbers from least to greatest

Answer:

x= 134 ± 2

Step-by-step explanation:

The ± symbol is used to mark the range of values that should be expected from the first number, 134.

7v + 12b = 640

12v + 6b = 456

Multiply the bottom equation by -2 in order to cancel out 12b with 6b.

7v + 12b = 640

- 24v -12b = -912

-17v = -272

17v = 272

v = 272/17

v = 16 students

If we use this: 7v + 12b = 640 ;then:

7(16) +12b = 640

112 +12b = 640

12b = 640 -112

12b = 528

b = 528/12

b = 44 students

So the number of students in each van is 16, and number of students in each bus is 44.

Yes, it indicates that the number of single people under the age of 25 is higher than the national percentage reported by the large insurance company, according to the calculated z-score.

here the sample size is = 25(n), therefore sample proportion will be, p⁰= 41/25 =0.774 .since the  null  hypothesis is  :H₀:p =0.68 and the alternative hypothesis  is  :H₁:p>0.68 .The  z-test  is :

Z=p⁰−p/ √(p(1-p)/n

  = 0.774-0.68/root(0.68(1-0.68)/52

    =1.453

The p-value for  the z score = 1.453 is 0.0731.Here the P-value is greater than the 5% level of significance. We come up short to dismiss the null hypothesis at the 5% level of significance. it can be concluded that the number of single individuals under the age of 25 is higher than the national percentage detailed by the large insurance company.

The growth rates in 1950, 1988 and 2010 are 13.9%, 23.4 and 29.8% respectively

The function of the growth rate equation is given as:

y = -0.0000081x^3+0.00267x^2+8.231

Rewrite properly

So, we have

y = -0.0000081x³ + 0.00267x² + 8.231

From the question, we have

x represents the number of years after 1900

In 1950, x = 50

So, we have

Growth rate in 1950, y = -0.0000081 x 50³ + 0.00267 x 50² + 8.231

Growth rate in 1950, y = 13.9

In 1988, x = 88

So, we have

Growth rate in 1988, y = -0.0000081 x 88³ + 0.00267 x 88² + 8.231

Growth rate in 1988, y = 23.4

In 2010, x = 110

So, we have

Growth rate in 2010, y = -0.0000081 x 110³ + 0.00267 x 110² + 8.231

Growth rate in 2010, y = 29.8

Hence, the growth rate in 2010 is 29.8%

The fraction -(13/10) × 6 is equal to the mixed fraction -7 whole number 4 divided by 5.

From the given fracion;

-(13/10) × 6 = -[13/(2×5)] ×2 × 3

we divide the common factor 2 for 10 and 6

-(13/10) × 6 = -(13/5) × 3

multiply the numerators

-(13/10) × 6 = (-13×3)/5

-(13/10) × 6 = -39/5

divide -39 by 5

-(13/10) × 6 = -7 whole number, 4/5 in mixed fraction

Step-by-step explanation:

If all 27 votes for hunger relief, that would be 100% or all of them.

The percent change from the old model to the new model estimation of a 5-year old dog's age is 41.66%  .

The traditional model involved multiplying the dog's age with seven to calculate their age in human years. for example if the age of dog is 3 years , so in human years he/she will be 3x7 = 21 years old in human years.

Here we calculate the age of 5-years old dog in human years. So we multiply the 5 with 7 and get the answer as 35 years .

As per the new convention 5-years old dos's age is nearly equal to 60 in human years.

So the difference in age in both the methods is

age difference = 60 - 35

                          =  25

So the percent change in age = (25/60) x 100

The domain includes all real numbers, and the range is y > 0

What are domain and range?

A function's domain and range are its constituent parts. A function's range is its potential output, whereas its domain is the set of all possible input values. Range, Domain, and Function. A is the domain and B is the co-domain if a function f: A B exists that maps every element of A to an element in B. 'b', where (a,b) R, provides the representation of an element 'a' under a relation R. The set of images is the function's range. In general, a function's domain and range are denoted as follows: Range(f) = f(x): x domain(f) and domain(f) = f(x): x R

Domain: The domain is the set of all possible x-values.

Range: The range of a function is the complete set of all possible resulting values of the dependent variable y.

We can see from the graph, x values include all real numbers and range ( y values greater than 0 because the graph line does not intersect at 0.

we know that

The domain of the function of the graph is the interval (-∞,∞)

That means the domain is all real numbers.

The range of the function of the graph is the interval is (0,∞)

The price of one sweater - x

From what the problem states, we can assume:

x + 4y = 55

4x + 5y = 110

Multiply both sides of x +4y = 55 by four. This results in 4x + 16y = 220. We then subtract 16y on both sides, resulting in 4x = 220 - 16y. We then insert this into the other equation, which, as a reminder, is 4x + 5y = 110. We replace 4x with 220 - 16y, which results in 220 - 16y + 5y = 110. Now, we can solve it.

The inverse of the given function is (f^-1)(x) = (1/2)×(√x  - 1) for x ≥ 0.

We are given a function f(x). The function f(x) is defined as (2x + 1)². The domain of the given function f(x) is x ≥ -1/2. We need to find the inverse of the function f(x).

Let us suppose that the function f(x) is represented by the variable "y".

y = f(x)

y = (2x + 1)²

Now we will take the square root on both sides of the equation.

√y = √[(2x + 1)²]

When we cancel out the even powers, we need to take the absolute value using modulus.

√y = |2x + 1|

We already know that x ≥ -1/2, so, modulus will open with a positive sign.

√y = +(2x + 1)

√y = 2x + 1

√y  - 1 = 2x

x = (1/2)×(√y  - 1)

At last, we replace the variables y and x by x and (f^-1)(x).

(f^-1)(x) = (1/2)×(√x  - 1) for x ≥ 0

The shapes maintain their equality regardless of how they are turned, flipped, or rotated before being cut out and stacked. We'll see that they'll be placed entirely on top of one another and will superimpose one another. Due to their identical radius and ability to be positioned directly on top of one another, the following circles are considered to be congruent.
