Gabe = 4x + 4y = 30

x = 3

y = 4.5

Step-by-step explanation:

4y = 30 - 4x

y = 7.5 - x

5x + 2(7.5 - x) = 24

3x + 15 = 24

x = 3

y = 7.5 - 3

Answer:

Infinitely many

Step-by-step explanation:

1. Subtract y from both sides:

y-y + 12 = y-y + 10 + 2

12 = 10 + 2

2. Simplify:

12 = 12

Because the left and right side are equal, then there are infinitely many solutions.

We can conclude that there is not enough evidence to suggest that the distribution of blood types in hospital patients is different from that of the general population at a significance level of 0.10.

Hypothesis testing is a statistical method that is used to make decisions about a population based on a sample of data.

It involves testing a null hypothesis (H0) against an alternative hypothesis (Ha) using statistical techniques.

We have,

We need to perform a hypothesis test to determine if the distribution of blood types in hospital patients is the same as that of the general population.

Let's set up the null and alternative hypotheses:

Null hypothesis:

The distribution of blood types in hospital patients is the same as that of the general population.

Alternative hypothesis:

The distribution of blood types in hospital patients is different from that of the general population.

We can use a chi-squared test to test the hypothesis.

First, we need to calculate the expected frequencies for each blood type based on the general population distribution:

Expected frequency of type A = 50 x 0.22 = 11

Expected frequency of type B = 50 x 0.28 = 14

Expected frequency of type O = 50 x 0.38 = 19

Expected frequency of type AB = 50 x 0.12 = 6

Next, we can calculate the chi-squared statistic:

[tex]$\chi^2 = \frac{(11-11)^2}{11} + \frac{(9-14)^2}{14} + \frac{(24-19)^2}{19} + \frac{(6-6)^2}{6} = 2.84$[/tex]

The degrees of freedom for the test is (4 - 1) = 3.

Using a chi-squared distribution table with 3 degrees of freedom and a significance level of 0.10, the critical value is 6.251.

Since the calculated chi-squared value (2.84) is less than the critical value (6.251), we fail to reject the null hypothesis.

Thus,

We can conclude that there is not enough evidence to suggest that the distribution of blood types in hospital patients is different from that of the general population at a significance level of 0.10.

Answer:

Let the number is in the form of xyz

Sum of the digits is 19

The second digit is one more than the first digit

The third digit is two more than the second digit

Substitute the values of y and z into the first equation and solve for x

Find the value of y and z

The number is 568

Answer:

(3x+4)(2x−5)

Step-by-step explanation:

The first term is,  6x2  its coefficient is  6 .

The middle term is,  -7x  its coefficient is  -7 .

The last term, "the constant", is  -20

Step-1 : Multiply the coefficient of the first term by the constant   6 • -20 = -120

Step-2 : Find two factors of  -120  whose sum equals the coefficient of the middle term, which is   -7 .

     -120    +    1    =    -119

     -60    +    2    =    -58

     -40    +    3    =    -37

     -30    +    4    =    -26

     -24    +    5    =    -19

     -20    +    6    =    -14

     -15    +    8    =    -7    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -15  and  8

                    6x2 - 15x + 8x - 20

Step-4 : Add up the first 2 terms, pulling out like factors :

                   3x • (2x-5)

             Add up the last 2 terms, pulling out common factors :

                   4 • (2x-5)

Step-5 : Add up the four terms of step 4 :

                   (3x+4)  •  (2x-5)

            Which is the desired factorization

Step-by-step explanation:

3/6probability of number cube lands on an even number

1/3 probability that it will land on the spinner

multiply 1/3 x 3/6 =3/18

let me know if i get it correct

The probability that on a student's turn, the number cube will land with an even number on the top face and the arrow on the spinner will stop on the blue(b) section is P = 3/18

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

The probability of the number cube landing with an even number on the top face is 3/6 or 1/2 since there are three even numbers (2, 4, and 6) out of the six possible outcomes (1, 2, 3, 4, 5, and 6)

The probability of the arrow on the spinner stopping on the blue section is 1/3 since there is only one blue section out of the three possible outcomes

To find the probability of both events occurring together, we multiply the probabilities of each event:

P(even number and blue section) = P(even number) × P(blue section)

P(even number and blue section) = 1/2 × 1/3

P(even number and blue section) = 1/6

P = 3/18

Therefore, the probability that, on a student's turn, the number cube will land with an even number on the top face and the arrow on the spinner will stop on the blue section is 1/6.

Hence , the probability is P = 3/18

Answer:

D.) The last table is the answer

Step-by-step explanation:

I finished the test.

Part A

Multiply each age with its corresponding frequency

Then add up those products

38+60+21+88+23 = 230

We divide that sum over the total frequency of 11 (since 2+3+1+4+1 = 11).

mean = 230/11 = 20.9 approximately

Nice work on getting the correct answer.

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

Part B

x = age of the new player

Adding x to the sum of the products 230, and then dividing over 11+1 = 12 will get us the new mean of 22.

The 230 represents the sum of the ages of the original eleven people. The expression 230+x represents the sum of the twelve ages.

So,

(230+x)/12 = 22

230+x = 12*22

230+x = 264

x = 264-230

x = 34

X= 30

Y=28

Step-by-step explanation:

It's a right-angle triangle. So, 3 x 30 will give you a 90 degree angle.

180-90=90

That means the next 2 angles should add to 90.

2x28=56

56+34=90
