Answer:

The value of x is 0.624.

Property used: Symmetric property of equality

Step-by-step explanation:

The expression to be solved is:

[tex]f (x) = 2.5\cdot (6.25x+0.5)-11[/tex]

Compute the solution as follows:

[tex]f (x) = 2.5\cdot (6.25x+0.5)-11[/tex]

       [tex]=(2.5\times 6.25\ x)+(2.5\times 0.5)-11[/tex]

∵ Distributive property (a (b + c) = ab + ac)

       [tex]=15.625x+1.25-11\\=15.625x-9.75[/tex]

Substitute equation equal to 0 to compute the value of x as follows:

[tex]0=15.625x-9.75\\\\15.625x=9.75\\\\[/tex]

∵ Symmetric property of equality if a = b then b = a

[tex]x=\frac{9.75}{15.625}\\\\x=0.624[/tex]

Thus, the value of x is 0.624.

3.)  Subtraction Property of Equality

4.)  ​Division Property of Equality

Answer:

a) The p value is a probability always between 0 and 1 and represent the evidence in favor of the alternative hypothesis if it's a low value then we have enough evidence to reject the null hypothesis otherwise we FAIl to reject the null hypothesis

b) For this case the result is important because the parameter established by the Public Healt is incorrect ,we obtain a significant result so then there is enough evidence to conclude that the true proportion of children that have been vaccinated against measles is lower than 91%

Step-by-step explanation:

For this case the system of hypothesis are:

Null hypothesis:[tex]p=0.91[/tex]  

Alternative hypothesis:[tex]p < 0.91[/tex]  

When we conduct a proportion test we need to use the z statisitc, and the is given by:  

[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)  

For this case after conduct the hypothesis we have the following p value obtained:

[tex] p_v = 0.0001[/tex]

Part a

The p value is a probability always between 0 and 1 and represent the evidence in favor of the alternative hypothesis if it's a low value then we have enough evidence to reject the null hypothesis otherwise we FAIl to reject the null hypothesis

Part b

For this case the result is important because the parameter established by the Public Healt is incorrect ,we obtain a significant result so then there is enough evidence to conclude that the true proportion of children that have been vaccinated against measles is lower than 91%

Answer:

Step-by-step explanation:

Hello!

The historical data suggests that the life expectancy in Argentina is equal to the life expectancy in Bolivia.

With the objective of testing if that it hasn't changed, the records of recently deceased people from Argentina and Bolivia were selected at random:

Group 1: Argentina

X₁: Years of life of a recently deceased Argentinian.

n₁= 265

X[bar]₁= 74.8 years

S₁= 4.1 years

Group 2: Bolivia

X₂: Years of life of a recently deceased Bolivian.

n₂= 300

X[bar]₂= 75.4 years

S₂= 4.3 years

The parameters of interest are the population means of the years of life of people in both countries:

H₀: μ₁ = μ₂

H₁: μ₁ ≠ μ₂

α: 0.05

The statistic to use is an approximate standard deviation, and since both samples are quite large, it is valid to use the sample standard deviations in place of the population standard deviations:

[tex]Z= \frac{(X[bar]_1-X[bar]_2)-(Mu_1-Mu_2)}{\sqrt{\frac{S^2_1}{n_1} +\frac{S_2^2}{n_2} } }[/tex]≈N(0;1)

[tex]Z_{H_0}= \frac{(74.8-75.4)-(0)}{\sqrt{\frac{16.81}{265} +\frac{18.49}{300} } }= -2.54[/tex]

The critical values for this test are:

[tex]Z_{\alpha /2}= Z_{0.025}= -1.96[/tex]

[tex]Z_{1-\alpha /2}= Z_{0.0975}= 1.96[/tex]

Using the critical value approach, the decision rule is:

If [tex]Z_{H_0}[/tex] ≤ -1.96 or if [tex]Z_{H_0}[/tex] ≥ 1.96, reject the null hypothesis.

If -1.96 < [tex]Z_{H_0}[/tex] < 1.96, do not reject the null hypothesis.

[tex]Z_{H_0}[/tex] ≤ -1.96 so the decision is to reject the null hypothesis.

So with a 5% significance level, there is enough evidence to reject the null hypothesis, you can conclude that the life expectancy in Argentina is different from the life expectancy in Bolivia.

x3 + 11x2 - 3x - 33

x2(x + 11) - 3(x + 11)

(x + 11) (x2 - 3) are the factors

Answer:

The number is 36.

Step-by-step explanation:

Given that 1/3 of a number is 12. So let's make this number into any variable, I will choose x which means that 1/3 of x is equals to 12. Next we have to write an expression :

[tex] \frac{1}{3} \times x = 12[/tex]

In order to solve x, you have to multiply 3 to both sides :

[tex] \frac{1}{3} \times x \times 3 = 12 \times 6[/tex]

[tex]x = 36[/tex]

To find out what number 12 is one-third of, we can set up an equation. Let's assume the unknown number is represented by "x".

According to the given statement, we can write the equation as: 12 = (1/3)x To solve for x, we need to isolate it on one side of the equation.

We can do this by multiplying both sides of the equation by 3, canceling out the fraction: 3 * 12 = (1/3)x * 3 36 = x Therefore, 12 is one-third of 36. In other words, if we take one-third of 36, it will equal 12.

$2.55 per kilogram bag of sugar.

Step-by-step explanation:

To calculate the cost of only 1 bag of sugar, you would take what you know - 2 kilograms costs $5.09 - and use that to determine your answer.

Since you know how much 2 bags costs, and you need to know the cost of 1, you would divide the cost of 2 bags of sugar by 2. (5.09 ÷ 2)

That equals 2.545, but since the problem is asking you to round to the nearest cent, you would end up with -------> $2.55

Answer:

The solutions are

x = -1, 1, -2√2, and 2√2.

Step-by-step explanation:

Given the equation

x^4 - 9x² + 8 = 0

Let u = x², then the equation becomes

u² - 9u + 8 = 0

u² - u - 8u + 8 = 0

(u² - u) - (8u - 8u) = 0

u(u - 1) - 8(u - 1) = 0

(u - 8)(u - 1) = 0

u - 8 = 0

=> u = 8

Or

u - 1 = 0

=> u = 1

For u = 8

=> x² = 8

=> x = ±√8 = ±2√2

For u = 1

=> x² = 1

=> x = ±√1 = ± 1

Answer:

3000 gallons of gasoline and 2000 gallons of kerosene

Step-by-step explanation:

The first thing is that 16 ¢ and 15 ¢ are 16 and 15 cents, therefore we can express it as $ 0.16 and $ 0.15 respectively.

Now, we can solve by means of a 2x2 system of equations, we have to:

"x" is the number of gallons of gasoline

"y" be the number of gallons of kerosene

x + y = 5000 => x = 5000 - y

0.16 * x + 0.15 * y = 780

replacing

0.16 * (5000 - y) + 0.15 * y = 780

800 - 0.16 * y + 0.15 * y = 780

-0.01 * y = 780 - 800

y = -20 / -0.01

y = 2000

Therefore x:

x = 5000 - 2000

x = 3000

which means 3000 gallons of gasoline and 2000 gallons of kerosene

Answer: 40,000

Step-by-step explanation:

Rounding 39,918.23 to the nearest thousands is 40,000.

The given decimal number is 39,918.23.

We need to round the given decimal to the nearest thousand.

We follow the given steps to round numbers to the nearest whole number:

Step 1- We look at the number we want to round.

Step 2- As we are rounding our number to the nearest whole, we mark the digit in the one’s place.

Step 3- Now we look at the ‘tenths’ place (the digit to the right of the decimal point).

Step 4- (i) If the digit in the tenths column is 0, 1, 2, 3 or 4, we will round down the number from one place to the nearest whole number.

(ii) If the digit in the tenths column is 5, 6, 7, 8 or 9, we will round up the number at the one’s place to the nearest whole number.

Step 5- Remove all the digits after the decimal point. The left-out number is the desired answer.

Now, in the given decimal, the number in the thousand places is 9, which is greater than 5, and then the number becomes 40,000.

Therefore, rounding 39,918.23 to the nearest thousands is 40,000.

Answer:

r = 3

Step-by-step explanation:

q = k / [tex]r^{2}[/tex]

k = q[tex]r^{2}[/tex] = 1.2 x 3 x 3 = 10.8

q = 10.8/[tex]r^{2}[/tex]

1.2 = 10.8/[tex]r^{2}[/tex]

r = [tex]\sqrt{10.8 /1.2}[/tex] = 3

As q is inversely proportional to r square the value of r is 1.66 when q is equal to 1.2

A ratio is a comparison between two similar quantities in simplest form.

Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant 'k' and vice versa.

In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.

Given, q is inversely proportional to r square which is,

q ∝ 1/r².

q = k/r².

q = 30 when r = 3, From this we'll have the value of the constant of proportionality(k).

30 = k/9.

k = 30/9.

k = 10/3.

Now, q = 1.2 and k = 10/3.

Therefore,

1.2 = (10/3)/r².

r² = (10/3)×(1/1.2).

r² = 10/3.6.

r² = 2.77.

r = 1.66
