Every day, Lucy's burrito stand uses 3/4 of a bag of tortillas. How many days will 3 3/4 bags of tortillas last?

We assume that the population standard deviation are known, the samples from each population are independent, the population is normally distributed if we use t test of two samples.

Given T test of significance has been used.

T test is a statistical test that is like z test. Z test is used when n>30 and t test is used when n<30. It is used in hypothesis testing.

We know that there are many test which can be used to test a hypothesis.

The requirements to perform a two sample t procedure are as follows:

1)The two samples have equal variance. Hence the variance should be known.

2) The samples for which the two sample t procedure is performed must be independent.

3) The data are in alignment with the normal distribution probability.

4) The sample are random samples taken from different respective population.

Hence when two sample t procedure is performed we have to assume population standard deviation is known and population is normally distributed.

The equation y = 3/4x describes the relationship

From the question, we have the following parameters that can be used in our computation:

The graph

The graph is a linear graph, and we have the following points on the graph

(x, y) = (0, 0) and (4, 3)

Because the line passes through the origin i.e. (0, 0), the equation that describes the relationship is then represented as

y = Y/X * x

Where

(X, Y) = (4, 3)

So, we have

y = 3/4x

The amount of pounds of clay left is given by the equation A = 0.51 pounds

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

The total amount of pounds of clay = 3.8 pounds

Now , the amount of clay used by Martha = ( 1/4 ) of the total

So , the amount of clay used by Martha = ( 1/4 ) x 3.8 = 0.95 pounds

And , the remaining amount of clay = 3.8 - 0.95 = 2.85 pounds

Now , the amount of clay used by Scott = ( 2/5 ) of the remaining

So , the amount of clay used by Scott = ( 2/5 ) x 2.85 = 1.14 pounds

And , the remaining amount of clay = 2.85 - 1.14 = 1.71 pounds

On simplifying the equation , we get

Now , the amount of clay used by Alison = 1.2 pounds

So , the remaining amount of clay = 1.71 - 1.2 = 0.51 pounds

Hence , the remaining amount of clay = 0.51 pounds

Hue is arranging chairs. She can form 2 rows of a given length with 5 chairs left over, or 6 rows of that

same length if she gets 11 more chairs. Complete the equation and solve it to find how many chairs are in

that row length. In your equation, use the variable x to represent the number of chairs in each row.

The equation is

There are

chairs in each row.

Let, no. of chairs in each row = x

There are 2 rows of given length with 5 chairs left over.

6 rows of the same length if given 11 more chairs 2x+5 will be equal to 6x

If 11 chairs are added to 2x+5 because 6x has 11 more chairs than 2x+5

=> 2x+5+11 = 6x

=> 2x+16 = 6x

=> 4x = 16

=> x = 16/4

=> x = 4

x=4 chairs in each row with 5 left over makes 2*4+5 = 13 chairs

add 11 chairs to 13 chairs and you get 24 chairs which is 6 rows of 4 chairs in each row.

-7 (1-8x) = 105

-7 - (-56x) = 105

-7 +56x = 105

+56x = 105 + 7

56x = 112

56x/56 = 112/56

x = 2

Let me know if you need more help!

Answer:

x = 2

Step-by-step explanation:

Rearrange the values: -7(1 - 8x) = 105 = -7(-8x + 1) = 105

Distribute: -7(-8x + 1) = 105 = 56x -7 = 105

Add 7 to both sides of the equation:  56x -7 = 105 = 56x -7 + 7 = 105 + 7

Simplify: 56x -7 + 7 = 105 + 7 = 56x = 112

Divide both sides of the equation by the same term: 56x = 112 = 56x/56  = 112/56

Simplify: 56x/56  = 112/56 = x = 2

Answer:

\( x = \dfrac{7 \pm 3i\sqrt{3}}{2} \)

Step-by-step explanation:

(x – 5)^2 + 3(x – 5) + 9 = 0

This is a quadratic equation in x - 5.

Let u = x - 5, then the quadratic equation becomes:

u^2 + 3u + 9 = 0

We can use the quadratic formula to solve for u.

\( u = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} \)

\( u = \dfrac{-3 \pm \sqrt{3^2 - 4(1)(9)}}{2(1)} \)

\( u = \dfrac{-3 \pm \sqrt{9 - 36}}{2} \)

\( u = \dfrac{-3 \pm \sqrt{-27}}{2} \)

\( u = \dfrac{-3 \pm 3i\sqrt{3}}{2} \)

Since u = x - 5, now we substitute x - 5 for u and solve for x.

\( x - 5 = \dfrac{-3 \pm 3i\sqrt{3}}{2} \)

\( x = \dfrac{-3 \pm 3i\sqrt{3}}{2} + 5 \)

\( x = \dfrac{-3 \pm 3i\sqrt{3}}{2} + \dfrac{10}{2} \)

\( x = \dfrac{7 \pm 3i\sqrt{3}}{2} \)

Answer:

Step-by-step explanation:

The statement that is true regarding the graphed functions is that: B. f(-2) = g(-2).

Mathematically, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

At point (2, 0), an equation of the line f(x) can be calculated by using the point-slope form:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

y - 0 = (-4 - 0)/(-2 - 2)(x - 2)

y = -x + 2

For line g(x), we have:

y - 4 = (-2 - 4)/(0 + 2)(x + 2)

y = -3(x + 2) + 4

y = -3x - 2

When x = 0, we have:

g(0) = 0 + 2 = 2

f(0) = 0 - 2 = -2.

When x = -2, we have:

g(-2) = -(-2) + 2 = 4

f(-2) = -3(-2) - 2 = 4.

Answer:

One motorcycle was going 44 miles and hour and the other motorcycle was going 8 miles an hour faster, so it was going 52 miles per hour.

Step-by-step explanation:

Distance = rate times time

Both motorcycles have a time of 3.  We do not know the rates, but we know that one motorcycle's rate was 8 miles an hour faster.  Let's call motorcycle 1's rate x then motorcycle 2's rate must be (x + 3)

Motorcycle 1

d = 3x

Motorcycle 2

d = 3(x +8)

We know that the total distance together is 288

3x + 3(x+8) = 288  Distribute the 3

3x + 3x + 24 = 288  Combine the 3's

6x + 24 = 288  Subtract 24 from both sides of the equation

6x = 264  Divide both sides by 6

x = 44

One motorcycle was going 44 miles and hour and the other motorcycle was going 8 miles an hour faster, so it was going 52 miles per hour.

Using the properties of similar triangles and ratio and proportion we get the vale of x as 2.8 units.

In the given figure the triangle ΔKFG and ΔFJH

KG is parallel to JH

Hence ΔKFG is similar to ΔFJH

Now using the property of similarity and proportion we can say that:

FG/FH = KF/JF

putting the values in the above proportion we get:

7 /(7+x) = 5/ 7

or, 49 = 35 +5 x

or, 14 = 5x

or, x =14/5

or, x = 2.8

The majority of ratio and percentage explanations involve using fractions.

A proportion states that two variables are equal, whereas a ratio is a fraction that is written as a:b. The two ratios given are equal to one another, as demonstrated by the proportional equation.

Hence the value of x is 2.8 units.

Yes it is divisible by 3. A number is fully divisible by three if its digit sum is also divisible by three, according to the rule of divisibility for three.

The divisibility rule is a concise and practical approach to check, often by looking at the integer's digits, whether a given integer is divisible by a given set divisor without actually executing division. Without actually doing the division procedure, you may quickly discover if a given number can be divided by a defined divisor using the divisibility test. When dividing two numbers exactly, the quotient must be an integer and the remainder must be zero.

add all the numbers,

1 + 2+ 3 + 4+ 5 = 15

The correct answer is A. The shape of the sampling distribution of x is that of a normal distribution and it depends on the sample size.The shape of the sampling distribution is normally distributed, and this shape is influenced by the sample size.

The sampling distribution of x refers to the distribution of sample means or sample proportions that we would obtain if we repeatedly drew samples from the same population. According to the Central Limit Theorem (CLT), when the sample size is sufficiently large (typically n ≥ 30), the sampling distribution of x will be approximately normally distributed regardless of the shape of the population distribution. This means that the shape of the sampling distribution will resemble a bell curve.

However, when the sample size is small (n < 30) and the population distribution is not strongly skewed or has outliers, the shape of the sampling distribution may still be approximately normal. On the other hand, if the sample size is small and the population distribution is highly skewed or has outliers, the sampling distribution may deviate from a perfect normal distribution.

In summary, the shape of the sampling distribution of x is generally that of a normal distribution when the sample size is sufficiently large, but it can deviate from normality when the sample size is small or when the population distribution has extreme characteristics. Therefore, the shape of the sampling distribution depends on the sample size.

Using trigonometric function the value of x is 51.3°.

What is trigonometric function?

The functions of an angle in a triangle are known as trigonometric functions, commonly referred to as circular functions. In other words, these trig functions provide the relationship between a triangle's angles and sides. There are five fundamental trigonometric functions: sine, cosine, tangent, cotangent, secant, and cosecant.

Here Let us take the given right triangle as ABC.

∠A = x , ∠B = 90° and AB = 25 , AC= 40

Now using Cosine ratio then

Cos  A = \(\frac{adjacent}{hypotenuse}\)

=> cos x = \(\frac{25}{40}\)

=> cos x = \(\frac{5}{8}\)

=> x = \(cos^{-1}\frac{5}{8}\)
