Answer:

Step-by-step explanation:

the first one becouse of the ratio 6:1

we know it cant be c there is no possible way so

its either a or b

if n=number of girls

6- girls and plussing will give you the correct answer

it is minus becouse of the ratio adding will give you more than the value

and minus will give exact value

Answer: n + ( n + 6) = 23

Answer:

x = 4, x = 8

Step-by-step explanation:

Given

(x - 7)(x - 5) = 3 ← expand factors using FOIL

x² - 12x + 35 = 3 ( subtract 3 from both sides )

x² - 12x + 32 = 0 ← in standard form

(x - 4)(x - 8) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x - 8 = 0 ⇒ x = 8

C.–1 and 4

Step-by-step explanation:

Solving the equations  y = –x² + 4x and y = x – 4

–x² + 4x = x – 4

x² - 4x + x = 4

x² - 3x = 4

x² - 3x + (3/2)² = 4 +  (3/2)²

(x - 3/2)² = 4 +  9/4

             = 6.25

x - 3/2 = √6.25                      or  x - 3/2 = -√6.25

x = 2.5 + 1.5                                        x = -2.5 + 1.5

= 4                                                        = -1

Cup of vinegar used per recipe = 1/5 cup

Amount of vinegar to be used for 4/5 of a recipe ;

1 cup recipe = 1/5 cup vinegar

4/5 cup recipe = x

Cross multiply :

x = 1/5 * 4/5

x = 4/25 cup

Hence, Sandeep will use 4/25 cup of vinegar

Step-by-step explanation:

The inequality can be seen graphed in the number line that I have created in the attached picture below. As you can see the open circle represents the value 1 1/4 and is an open circle because it is not included in the inequality. This is because the variable z is less than but NOT equal to 1 1/4. Also since z is any number less than 1 1/4 then the number line goes towards negative infinity.

Step-by-step explanation:

First we have to find the equation of the line represented in the table; for that we have to find it's slope  and it's y-intercept  and then write it in the following form:

The slope  of the line we get from first two points:

thus we have

we find  by putting the point  into the function:

Thus we have

Now we have to find where this line intersects with ; to do this we just substitute  with :

We have the x-coordinate of  the intersection.

We find the y-coordinate by substituting  into :

Answer:

Step-by-step explanation:

the answer is up at the top

The probability that at least 1 doesn't use a computer at work is 0.8065.

The probability that all 5 use a computer in their jobs is 0.1935.

Suppose we let X represent the no. of women that make use of computers at work. A given random variable X which approaches a binomial distribution with the following data n = 5 and p = 0.72 has a probability function:

[tex]\mathbf{P(X=x) = \left \{ {{(^5_x)(0.72)^x(0.28)^{5-x}, \ X = 0,1,2,...5} \atop {0, \ \ \ \ \ \ \ \ \ \ \ \ elsewhere }} \right.}[/tex]

a.)

Then, the probability that at least 1 doesn't use a computer at work can be computed as:
[tex]\mathbf{1-P(X=5) =1 - (^5_5)(0.72)^5(0.28)^{5-5}}[/tex]

[tex]\mathbf{1-P(X=5) =1 - (0.72)^5}[/tex]

[tex]\mathbf{1-P(X=5) =1 - 0.1935}[/tex]

⇒ 0.8065

b.)

The probability that all 5 make use of computers at their job is;
[tex]\mathbf{P(X=5) = (^5_5) (0.72)^5 (0.28)^{5-5}}[/tex]

[tex]\mathbf{P(X=5) = 1 \times (0.72)^5 \times 1}[/tex]

P(X = 5) = 0.1935

Step-by-step explanation:

Answer:

A) only figure 1 and figure 2

Step-by-step explanation:

Answer: Choice A) only figure 1 and figure 2

===========================================================

Explanation:

Let's assume that figure 2 is similar to figure 3.

If this is the case, then the horizontal portions would divide to 30/15 = 2, showing that figure 3 has sides that are twice as long compared to figure 2. But then notice that the vertical sides divide to 36/24 = 1.5, which doesn't match with the previous result of 2.

Figures 2 and 3 cannot be similar for that reason.

Also, figures 1 and 3 are not similar either. Note the horizontal portions divide to 30/10 = 3 while the vertical portions divide to 36/16 = 2.25; the results 3 and 2.25 don't match.

We eliminate answers B, C and D. The only thing left is choice A.

-------------------

To verify choice A is true, we divide each corresponding piece like so

Each division leads to the same result of 1.5, meaning that figure 2's side lengths are 1.5 times longer than the corresponding side lengths of figure 1. So this confirms that figure 1 is similar to figure 2.
