Answer:

65⁰ because the opposite angles of parallelogram are equal...

False. The statement is not entirely accurate. While significantly different sample variances can impact the assumptions of a t-test, it does not necessarily mean that a t-test cannot be conducted.

In traditional t-tests, there is an assumption of equal variances between the compared groups or populations. This assumption is known as the assumption of homogeneity of variances. If the sample variances are significantly different, it violates this assumption.

However, there are alternative versions of the t-test that can be used when the variances are not equal, such as the Welch's t-test or the modified t-test. These tests do not assume equal variances and can be applied when the variances are significantly different.

Therefore, it is possible to conduct a t-test even when the sample variances are significantly different, using appropriate modifications to the test. However, it is essential to consider the validity and appropriateness of the chosen test based on the specific circumstances and assumptions of the data.

\(\Large\boxed{\tt Answer:~x=\frac{5}{7} }\)

\(\tt Step-by-step~explanation:\)

Remember: PEMDAS - Parentheses, exponents, multiply/divide, add/subtract

Distribute: 9(1+x) = 9+9x

19 - 5x = 9 + 9x

Add 5x to both sides of the equation and subtract 9 from both sides.

19 - 5x + (5x) = 9 + 9x + (5x)

19 - (9) = 9 - (9) + 14x

10 = 14x

Divide both sides by 14 to get the variable on its own.

10/14 = 14x/14

10/14=x

Step-by-step explanation:

The zeros of functions are the x-values when y = 0, i.e the point(s) at which the line crosses the x-axis.

To find the zeros of the given functions, set the function to zero and solve for x.

Given function:

\(y=5(x-3)(x+5)\)

Set the function to zero:

\(\implies 5(x-3)(x+5)=0\)

\(\implies \dfrac{5(x-3)(x+5)}{5}=\dfrac{0}{5}\\\)

\(\implies (x-3)(x+5)=0\)

Using the Zero Product Property, set each factor equal to zero and solve for x:

\(\implies (x-3)=0 \implies x=3\)

\(\implies (x+5)=0 \implies x=-5\)

Therefore, the zeros of the function are 3 and -5.

Given function:

\(y=(x-7)^2\)

Set the function to zero and solve for x

\(\implies (x-7)^2=0\)

\(\implies \sqrt{(x-7)^2}=\sqrt{0}\)

\(\implies x-7=0\)

\(\implies x=7\)

Therefore, the zero of the function is 7 (with multiplicity 2).

The slope of the line that passes through the coordinates is -6/5.

The slope of the line is given by;

m = (y₂ - y₁)/(x₂ - x₁)

Where, the coordinates are given.

(x₁ ,y₁) = (2, 8)

(x₂, y₂) = (-3, 14)

The probability that the average bacteria count for one day is between 2350 and 2650 bacteria per milliliter is 0.3485.

Given that the bacteria count in milk follows a normal distribution with a mean of 2500 bacteria per milliliter and a standard deviation of 200 bacteria per milliliter.

The question requires finding the probability that the average bacteria count for one day is between 2350 and 2650 bacteria per milliliter.

Therefore, we can use the standard normal distribution to find the probability. To convert the normal distribution to the standard normal distribution, we use the formula:z = (x - µ) / σz = (2350 - 2500) / 200z = -0.75z = (2650 - 2500) / 200z = 0.75

Therefore, the probability of the average bacteria count for one day being between 2350 and 2650 bacteria per milliliter is:

P(-0.75 < z < 0.75)

The area under the standard normal distribution curve between -0.75 and 0.75 is equal to 0.3485.

Thus, the probability that the average bacteria count for one day is between 2350 and 2650 bacteria per milliliter is 0.3485.

Answer: y = 5x + 26

Step-by-step explanation:

To find the equation of a line that is perpendicular to the given line y = -1/5x + 1 and passes through the point (-5, 1), we need to determine the slope of the perpendicular line. The given line has a slope of -1/5. Perpendicular lines have slopes that are negative reciprocals of each other. So, the slope of the perpendicular line will be the negative reciprocal of -1/5, which is 5/1 or simply 5. Now, we have the slope (m = 5) and a point (-5, 1) that the perpendicular line passes through.

We can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1)

Substituting the values, we get:

y - 1 = 5(x - (-5))

Simplifying further:

y - 1 = 5(x + 5)

Expanding the brackets:

y - 1 = 5x + 25

Rearranging the equation to the slope-intercept form (y = mx + b):

y = 5x + 26

Therefore, the equation of the perpendicular line that passes through the point (-5, 1) is y = 5x + 26.

Therefore , the solution of the given problem of unitary method comes out to be a 2-liter soda costs $4.98 and a platter of nachos costs $11.99.

The measurements taken from this femtosecond section must be multiplied by two in order to complete the task using the unitary variable technique. In essence, the characterised by a group and the hue groups are both removed from the unit approach when a desired object is present. For example, 40 pens with a expression price will indeed cost Inr ($1.01). It's possible that one country will have total influence over the approach taken to accomplish this. Almost every living creature has a distinctive quality.

Here,

Let's use "N" for the price of a platter of nachos and "S" for the price of a 2-liter soda.

The first aspect of the issue reveals that:

=> 5N + 2S = 67.87

The second component of the issue reveals the following to us:

=>2N + S = 27.94

=> S = 27.94 - 2N

When we use this expression in place of S in the first equation, we obtain:

=> 5N + 2(27.94 - 2N) = 67.87

When we simplify and account for N, we obtain:

=> 5N + 55.88 - 4N = 67.87\sN = 11.99

We can determine S by substituting this number for N in the second equation:

=> 2(11.99) + S = 27.94\sS = 4.98

As a result, a 2-liter soda costs $4.98 and a platter of nachos costs $11.99.

interest is approximately $29,138.27. To calculate the amount accumulated in thirty years with monthly savings and quarterly compounding interest, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A is the final amount accumulated

P is the monthly savings ($35)

r is the annual interest rate (5% or 0.05)

n is the number of compounding periods per year (quarterly, so 4)

t is the number of years (30)

Substituting the values into the formula:

A = 35(1 + 0.05/4)^(4*30)

A = 35(1 + 0.0125)^(120)

A = 35(1.0125)^(120)

A ≈ $29,138.27

Step-by-step explanation:

The computation of the perimeter of the rectangle is given below:

first we determine the side of each tile i.e.  

l² = A

l² = 49cm²

l = √49cm²

l = 7cm

now we calculate the perimeter i.e.  

P = 2 (3 (7cm) + 2 (7cm))

= 2 (21cm + 14cm)

= 2 (35cm)

= 70cm

Hence, the perimeter of the rectangle is 70 cm

Answer:6.66

Step-by-step explanation:

The position value, r(t) is equals to the (t³/6)k + 2j and velocity value, v(t) is equals to ( t²/2 )k + 4i , for a(t) = tk, v(0) = 4i, r(0) = 2j.

Acceleration is defined as the rate of change of the velocity of an object with respect to time. Accelerations are vector quanty.

a = dv/dt

We have the following informations are available,

Initial velocity, v(0) = 4i

Initial position, r(0) = 2j

Acceleration at any time "t",

a(t) = tk

we have to determine the value of v(t) and r(t).

As we know, a(t) = dv(t)/dt = tk

integrating the above equation ,

v(t) = ∫tk dt = ( t²/2 )k + c

at t = 0 , v(0) = 0 + c = 4i ( since, v(0) = 4i

=> c = 4i

So, v(t) = ( t²/2 )k + 4i

Also, velocity is calculated by derivative of postion (r) with respect to time.

=> v(t) = dr(t) /dt

=> r(t) = ∫ v(t) dt

=> r(t) = ∫ ( t²/2 )k dt

integrating value of the right hand side,

r(t) = ( t³/2×3 )k +d

= (t³/6)k + d

At t = 0, r(0) = (0/6)k + d

=> r(0) = d = 2j

so, r(t) = (t³/6)k + 2j

Hence, the required position and velocity are

(t³/6)k + 2j and ( t²/2 )k + 4i.
