Answer:

y=14+(2/3x)

Step-by-step explanation:

Your main goal is to get Y by itself on one side.

To start subtract 2x from both sides. This will give you -3y=42-2x.

Then you divide both sides by -3 to get Y by itself.

That will leave you with ...

y=14+(2/3x)

(remember the negatives cancel each other out)

7 students took only Math.

To show the information in a Venn diagram, we can draw three overlapping circles representing Math, Biology, and English courses. Let's label the circles as M for Math, B for Biology, and E for English.

52 students were taking a Math course (M)

50 students were taking a Biology course (B)

51 students were taking an English course (E)

16 students were taking both Math and English (M ∩ E)

20 students were taking both Math and Biology (M ∩ B)

18 students were taking both Biology and English (B ∩ E)

9 students were taking all three courses (M ∩ B ∩ E)

We can now fill in the Venn diagram:

     M

    / \

   /   \

  /     \

 E-------B

Now, let's calculate the number of students who took only Math. To find this, we need to consider the students in the Math circle who are not in any other overlapping regions.

The number of students who took only Math = Total number of students in Math (M) - (Number of students in both Math and English (M ∩ E) + Number of students in both Math and Biology (M ∩ B) + Number of students in all three courses (M ∩ B ∩ E))

Number of students who took only Math = 52 - (16 + 20 + 9) = 52 - 45 = 7

Answer:

y = - 2x + 9

Step-by-step explanation:

From y = -2x + 1

comparing with y = mx + c

slope (m) = - 2

Writing in point slope form

y - y1 = m(x - x1)

y - 1 = -2( x - 4)

y - 1 = -2x + 8

Now writing in slope intercept form

Step-by-step explanation:

There is no need to distribute, just set each parenthesis to equal to zero.

p(x)= (x-3)(x+3)(2x+1)

         X-3=0                     x+3=0                      2X+1=0

If she has increased by 75% in a week to get 14000 points then  we can say that 175% times a number has to equal 14,000 , where the number of points she had last week.

175% * x = 14000

1.75x =14000     Divide both sides by 1.75

x= 8000

So she had 8000 points last week.

Check:

175% * 8000= 14000

1.75 * 8000 = 14000

  14000 = 14000

Answer:

8,000 points

Step-by-step explanation:

x + 0.75x = 14,000 (the initial amount of points X plus 0.75x)

1.75x = 14000

x = 14000/1.75

x = 8,000

The expression with a variables is 7x²y when x  is 3 and y is 9 is 567.

Given that,

The expression with a variables is 7x²y.

We have to find the value when x  is 3 and y is 9.

Any thing that has multiple possible values is considered a variable. What does that mean, then? A variable is anything that could possibly change. Age, for example, might be considered a variable because it might signify different things to different people or to the same person at different periods. A person's nationality can function similarly by having a value assigned to it.

By substituting in the expression we get,

7(3)²(9)

7×9×9

567

Therefore, the expression of variables 7x²y when x  is 3 and y is 9 is 567.

Step-by-step explanation:

Option-C is correct that is the algebraic expression of the function F = (x +y +z').(x +y' +z').(x' +y +z) from the circuit in the picture.

Given that,

We have to find what is the algebraic expression of the function F.

In the picture we can see the diagram by using the circuit we solve the function F.

We know that,

From the circuit for 3 - to - 8 decoder,

D₀ = \(\bar{x}\bar{y}\bar{z}\)

D₁ = \(\bar{x}\bar{y}{z}\)

D₂ = \(\bar{x}{y}\bar{z}\)

D₃ = \(\bar{x}{y}{z}\)

D₄ = \({x}\bar{y}\bar{z}\)

D₅ = \({x}\bar{y}{z}\)

D₆ = \({x}{y}\bar{z}\)

D₇ = xyz

We can see bubble after D₀ to D₇ in the circuit,

So, Let A = \(\bar{D_1}\) = \(\overline{ \bar{x}\bar{y}{z} }\) = x + y + \(\bar{z}\)

Now, Let B = \(\bar{D_3}\) = \(\overline{ \bar{x}{y}{z} }\) = x + \(\bar{y}\) + \(\bar{z}\)

Let C = \(\bar{D_4}\) = \(\overline{ {x}\bar{y}\bar{z} }\) = \(\bar{x}\) + y + z

Now, Output F = A.B.C

F = (x + y + \(\bar{z}\)).(x + \(\bar{y}\) + \(\bar{z}\)).(\(\bar{x}\) + y + z)

F = (x +y +z').(x +y' +z').(x' +y +z)

Therefore, The algebraic expression of the function F = (x +y +z').(x +y' +z').(x' +y +z).

The type of hypothesis test to be used in this scenario is a one-sample t-test with a two-tailed alternative hypothesis.

The problem is asking to conduct a hypothesis test to determine whether the bag filling machine works correctly at the 433 gram setting.

The hypothesis test would involve a null hypothesis (H0) and an alternative hypothesis (Ha).

The null hypothesis is typically the hypothesis of "no effect" or "no difference" and is denoted as H0. In this case, the null hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is equal to 433 grams. Therefore, the null hypothesis would be:

H0: μ = 433

The alternative hypothesis (Ha) is the hypothesis that we want to test, and it is denoted as Ha. In this case, the alternative hypothesis would be that the mean weight of potato chips in the bags filled by the machine at the 433 gram setting is not equal to 433 grams. Therefore, the alternative hypothesis would be:

Ha: μ ≠ 433

To conduct the hypothesis test, we would need to calculate the test statistic and compare it to the critical value. Since the sample size is large (n=301) and the population variance is unknown, we would use a t-test with a level of significance of 0.02.

If the calculated t-value falls outside the critical t-value, we would reject the null hypothesis and conclude that the bag filling machine does not work correctly at the 433 gram setting.

If the calculated t-value falls within the critical t-value, we would fail to reject the null hypothesis and conclude that there is not enough evidence to suggest that the bag filling machine does not work correctly at the 433 gram setting.

Step 1: y-2=6x+12

Step 2: Add 2 on both sides

y-2+2=6x+12+2

Answer : y=8x+14

1) What mistake did I made?

You made a mistake in step 2,

When adding polynomials, you add only like terms. i.e

y-2+2=6x+12+2

y=6x+14

2 should be added with 12 only and not with 6x as 6x and 2 are not like terms.

2) Suggestion to avoid Such mistake in the future.

When adding polynomials, You should add only like terms.

Like terms are those that have same degree of variables i,e

2x and 3x, 2x^2 and 3x^2, 2 and 3 they all are like terms.

You can add 2x and 3x but can't add 2x and 2x^2 as they are not like terms.

Expressing x² + 4x – 7 in the form (x + p)² - q, where p and q are integers, we get p = 2 and Q= 11

Integer:

An integer is the number zero (0), a positive natural number (1, 2, 3, etc.), or a negative integer with a minus sign (-1, -2, -3, etc.). A negative number is the additive inverse of the corresponding positive number. In the language of mathematics, sets of integers are usually denoted by a bold Z.

To find: To express x² + 4x - 7 in the form (x+ p)² - q and determine the values of p and q.

The values of p and q are 2 and 11 respectively.

By completing the square method;

⇒ p = (4/2) = 2.

Therefore,

by expanding (x+ p)² i.e., (x+2)²

By expanding the above (x+2)² We have;

x² + 4x + 4

However,

The question is given as x²+4x-7

Therefore, by comparison between;

x² + 4x + 4 and x²+4x-7; we have:

x² + 4x + 4 = x²+4x-7

⇒ 4 - q = -7,

and, q = 7+4

⇒ q = 11

The values are p =2 and q = 11.

To calculate the probability of selecting a six-digit number with digits summing up to 52 and being divisible by 11, we need to determine the number of valid numbers meeting these criteria and divide it by the total number of six-digit numbers with digits summing up to 52. The resulting probability will depend on the specific calculation.

To find the probability, we first need to calculate the number of six-digit numbers whose digits sum up to 52. This involves finding all possible combinations of digits that add up to 52. However, without further information about restrictions or patterns, it is challenging to provide an exact count.

Next, we need to determine how many of these numbers are divisible by 11. A six-digit number is divisible by 11 if the difference between the sum of its odd-positioned digits and the sum of its even-positioned digits is either 0 or a multiple of 11.

By calculating the count of six-digit numbers satisfying these divisibility conditions, we can then divide it by the total count of six-digit numbers with digits summing up to 52 to obtain the probability. The specific probability will vary depending on the calculations involved, but it is expected to be relatively low due to the specific conditions required for both the digit sum and divisibility by 11.
