If 4 dollars can be exchanged for 114.12 Russian​ rubles, how many Russian rubles can be obtained for 1500 ​dollars?

Answer: Margin of Error for the given CI is 0.08

Step-by-step explanation:

Given the data in the question;

it is a symmetric class interval hence, sample proportion p = (0.50 + 0.66) / 2

p = 1.16 / 2

sample proportion p = 0.58

Margin of Error E will be;

E = 1/2 × length of Confidence interval

Margin of Error E = 1/2 × ( 0.66 - 0.5)

Margin of Error E = 1/2 × 0.16

Margin of Error E = 0.08

Therefore; Margin of Error for the given CI is 0.08

Step-by-step explanation:

First divide 15 hours by 5 :

15/5 = 3

So, we obtain that the cell will double 3 times

since the initial number o f cells is 38

5hours = 38x2 = 76

10 hours = 76x2= 152

15 hours =152 x2 = 304

304 cells

Step-by-step explanation:

A 1.5 standard deviations above the mean IQ score is 122.5.

An expression that depicts the relationship between two or more numbers and variables is called an equation.

A dependent variable is one that depends on another variable, whereas an independent variable does not depend on any other variable for its value.

Giving the z score are:

z is calculated as (raw score - mean) / standard deviation.

with a standard deviation of 15 and a mean of 100. The z-score of 1.5 is equal to the IQ score that is 1.5 standard deviations above the mean, so:

1.5 = (x - 100)/15

x = 122.5

A 1.5 standard deviations above the mean IQ score is 122.5.

Answer:

the 40th number in the pattern is 9

Using the z-distribution, it is found that the margin of error for a 99.7% confidence interval is of:

D. 9

It is given by:

\(M = z\frac{\sigma}{\sqrt{n}}\)

In which:

By the Empirical Rule, 99.7% of the measures are within 3 standard deviations of the mean, hence z = 3. The other parameters are given as follows:

\(\sigma = 36, n = 144\).

Hence:

\(M = z\frac{\sigma}{\sqrt{n}} = 3\frac{36}{\sqrt{144}} = 3 \times 3 = 9\)

Hence option D is correct.

4y(3x+2)–2(3x+2)

(4y–2)(3x+2)

2(2y–1)(3x+2)

The Factor of given equation  \(4y(3x+2)-2(3x+2)\)   is    \((2y-1) (6x+4)\) .

Factor in an equation is something which is multiplied by something else or we can say that numbers or the variables that are multiplied together.

We have,

 \(4y(3x+2)-2(3x+2)\)  

So, first simplify the expression,

      \(12xy+8y -6x-4\)

⇒    \(12xy-6x+8y-4\)

⇒     \(6x(2y-1)+4(2y-1)\)

From we can see that \((2y-1)\) is common in both terms,

Therefore,

⇒    \((2y-1) (6x+4)\)

So,    \((2y-1) (6x+4)\)  is the factor of the given expression.

Hence, we can say that the Factor of given equation \(4y(3x+2)-2(3x+2)\)   is    \((2y-1) (6x+4)\) .

Step-by-step explanation:

given the point 23 44 and 50. To determine if the right triangle, you want to find the slopes, the slope of rs the slope of S. T. And the slope of R. T. The slope is always the difference of your Y coordinate. So if it's R. S would be four minus 3/4 minus two. Difference of the Y coordinates Over the difference of the x coordinates, that would be 1/2 the scope of S. T. Using points S and T Would be 0 -4/5 -4. That's negative for over one or -4. In the soap of R. T would be zero minus 3/5 minus two, which would be negative 3/3, Which is positive one. So since we don't have any slopes that are opposite reciprocal als, then there are no perpendicular lines, so not a right triangle. Okay, no perpendicular lines.

Based on the coordinates of triangle RST, we can infer that triangle RST is not a right-angled triangle.

For this to be a right-angled triangle, the Pythagoras theorem has to apply where:

Largest side² = Side A² + Side B²

Lengths of the triangle:

RS² = (4 - 2)² + (4 - 3)²

= 5

ST² = (5 - 4)² + (0 - 9)²

= 17

TR² = (2 - 5)² + (3 - 0)²

= 18

We can see that:

18 ≠ 17 + 5

This is therefore not a right-angled triangle.

Answer:

area is 50.24 feet^2

Step-by-step explanation:

Circumference of the logo=25.12

2πr=25.12

r=25.12/(2×3.14)

r=25.12/6.28

r=4feet

So area of logo=πr^2

=3.14×4×4

=3.14×16

=50.24feet^2

So the area is 50.24 feet^2

It is shown below that the partition of G into left cosets of H is different from its partition into right cosets when n ≥ 3.

Let us first find the left cosets of H in G:

H = {1, s₀}

s₁H = {s₁, s₁s₀}

s₂H = {s₂, s₂s₀}

s₃H = {s₃, s₃s₀, s₂s₁, s₂s₁s₀}...

Now, find the right cosets of H in G:

H = {1, s₀}

Hs₁ = {s₁, s₀s₁}

Hs₂ = {s₂, s₀s₂}

Hs₃ = {s₃, s₀s₃, s₁s₂, s₀s₁s₂}...

Observe that the left cosets of H in G and the right cosets of H in G are not the same when n≥3. This is because s₁s₀ is not in H, but s₀s₁ is in H.

Therefore, the left coset s₁H is not the same as the right coset Hs₁. Similarly, s₂s₁s₀ is not in H, but s₀s₁s₂ is in H, so the left coset s₃H is not the same as the right coset Hs₃.

Thus, it is shown that the partition of G into left cosets of H is different from its partition into right cosets when n≥3.
