Which is the most accurate way to estimate 68% of 23?​

Answer:

28.4

Step-by-step explanation:

IJ corresponds to FG, and JK corresponds to GH. So, x/6 = 52/11. 11x = 312, x = 28.36, which rounds to 28.4

Answer:

The answer is A, C, and D

Step-by-step explanation:

Given: [tex] {x}^{2} - 7x + 7y - {y}^{2} [/tex]

Now factoring them,

[tex] = > (x - y)(x + y) - 7(x - y)[/tex]

[tex] = > (x - y)(x + y - 7)[/tex]

Therefore, the answer to the question is [tex] (x - y)(x + y - 7)[/tex]

Answer:

The mean is 30

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Since you have a right triangle, you can use the Pythagorean theorem.

a² + b² = c²

x² + 5² = 10²

x² + 25 = 100

x² = 75

x = √75

x = 5√3 = 8.66...

x = 9

Answer:

x - 2

Step-by-step explanation:

If (x - h) is a factor of f(x) then f(h) = 0

Here f(2) = 0 , then x - 2 is a factor of f(x)

Using the hypergeometric distribution, it is found that there is a 0.4286 = 42.86% probability of getting 2 of the same colour.

The marbles are chosen without replacement, hence the hypergeometric distribution is used to solve this question.

The formula is:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

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

The parameters are:

In this problem:

The probability of getting 2 of the same colour is the sum of P(X = 0), which is both red, with P(X = 2), which is both blue, then:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}C_{N-k,n-x}}{C_{N,n}}[/tex]

[tex]P(X = 0) = h(0,7,2,3) = \frac{C_{3,0}C_{4,2}}{C_{7,2}} = 0.2857[/tex]

[tex]P(X = 2) = h(2,7,2,3) = \frac{C_{3,2}C_{4,0}}{C_{7,2}} = 0.1429[/tex]

Hence:

[tex]p = P(X = 0) + P(X = 2) = 0.2857 + 0.1429 = 0.4286[/tex]

0.4286 = 42.86% probability of getting 2 of the same colour.

Answer:

Step-by-step explanation:

10x+14=94 so it will be x=8

Answer:

No, Albert's answer is not correct

Step-by-step explanation:

For illustrative purposes, let's say the object is a rectangle with width 2cm and length 6cm.  

Therefore, area = width x length = 2 x 6 = 12 cm²

If the scale factor is 1 : 3, then each side of the real object should be 3 times larger than the scale drawing.

So the width = 2 x 3 = 6 cm

and the length = 6 x 3 = 18 cm

Therefore, the area of this rectangle would be 6 x 18 = 108 cm²

So the scale factor of the area is:  12 : 108 = 1 : 9

so Alberto's answer is incorrect, as 12 : 36 is NOT 1 : 9

Answer:

y = x/5 - 4

second option is the correct answer.

Step-by-step explanation:

y = -5x+4

y = mx+b

m = -5

Now

Slope of the line perpendicular to a line would be the negative proprtional of the slope of the line.

so,

For the points (5,-3) and (10,-2)

m = 1/5

y = mx + b

or, -3 = 1/5 × x + b

or, -3 = 1/5 × 5 + b

or, -3 = 1+b

so, b = -4

Now,

y = mx+b

or, y = 1/5 × x + (-4)

or, y = x/5 - 4

Answer:

I believe the answer is x less than > with a line under it 83.33.

          The value of x in the algebraic expression is -2.5

An algebraic expression is the representation of numbers with variables with the purpose of solving for the variable. The variables are expressed by using alphabetical letters, here it is (x).

From the given algebraic expression, we have:

4x + 2 = -8

Collect like terms

4x = -8 - 2

4x = - 10

Divide both sides by 4

[tex]\mathbf{\dfrac{4x}{4} = \dfrac{-10}{4}}[/tex]

x = -2.5

Step-by-step explanation:

Set up a proportion and solve it.

drawing size     :     real size

      14 cm          :           x

       2 cm          :          29 m

14/x = 2/29

f(x) = g(x) at 0 and 1.

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

Given

 x                         f(x) = [tex]\rm 3^x[/tex]                   g(x) = 2x + 1

2                              9                                 5

The solution to f(x)=g(x).

It is clear that at x = 0 and 1, f(x) = g(x).

Thus, f(x) = g(x) at 0 and 1.
