Answer:

A) 13/20

Step-by-step explanation:

65% in simplest form,

65/100

= 13/20 (Divided by five)

Answer:

\(\frac{13}{20}\).

Step-by-step explanation:

We can begin by converting 65% to a fraction over 100. 65% converts to 0.65, or \(\frac{65}{100}\).

We can simplify this down. Both 65 and 100 share a common factor of 5, which allows us to produce a new fraction:

\(\frac{65}{100} = \frac{13}{20}\)

Therefore, the simplified version is \(\frac{13}{20}\).

The p-value is 0.1533, so p-value>0.05 fail to reject the null hypothesis. There is insufficient evidence to support the claim p-value greater than the significance level 0.05.

Consider the above given that

⇒\(& \alpha=0.05 \quad \mathrm{n}=34 \mathrm{~s}^2=0.0005 \\\)

⇒\(H_{0} : \sigma^2 \leq 0.0004 \\\)

⇒\(H_{a} : \sigma^2 > 0.0004\)

The null and alternative hypothesis test statistic:

⇒\(& \mathrm{x}^2=\left(\frac{\mathrm{n}-1}{\sigma^2}\right) \mathrm{s}^2 \\\)

\(& =\left(\frac{34-1}{0.0004}\right) 0.0005 \\\)

⇒\(& \mathrm{x}^2=\left(\frac{33}{0.004}\right) \times 0.0005 \\\)

\(& =82,500 \times 0.0005 \\\)

⇒\(& \mathrm{x}^2=41.25\)

⇒\(h_{0} : $\sigma^2$ is that or equal to $0.0004$\)

⇒\(h_{a} : $\sigma^2$ is greater that $0.0004$\)

⇒p value=p(z>41.25)

⇒p value=0.1533

By using P Value from Chi-Square Calculator

⇒p value=0.1533

⇒P value >0.05

Fail to reject the null hypothesis.

Therefore, the p-value is 0.1533, so p-value>0.05 fail to reject the null hypothesis.

The solution of the corresponding system of linear equations is: (X1, X2, X3, X4) = (-9s, 10s, -4s, t).

The reduced row echelon form of the matrix is:

1 0 0 -9

0 1 0 10

0 0 1 -4

0 0 0 0

This tells us that the system of linear equations has the following solution:

X1 = -9X4

X2 = 10X4

X3 = -4X4

The system is dependent, so we assign the free variables the parameters s and t:

X1 = -9s

X2 = 10s

X3 = -4s

X4 = t

The probability of getting 21, when first card is an ace and the second card is a queen = 0.024133.

The term blackjack means that you get a value of 21 with only two cards.

Number of cards in a deck of cards = 52

There are 4 types of cards in a deck of cards - spades, clubs, hearts, and diamonds, out of which spades and clubs are black in colour.

Given that first card is Ace and second one is a Queen.

Odds of getting an Ace are 4/52, odds of the next being Queen is 16/51.

P(blackjack)=4×16/(52/2).

where P is used for probability .

Probability: Probability is simply how likely something is to happen. Whenever we are unsure about the outcome of an event, we can talk about the probabilities of certain outcomes. The analysis of events governed by probability is called statistics.

Probability of getting an ace followed by a queen card: 4/52 * 16/51 = 0.024133.

Answer:

k=70

Step-by-step explanation:

So we know x=-5 so lets replace x with -5 in this equation:

6x+100= 6(-5)+100

6(-5)=-30

-30+100=70

so we know that 6(-5)+100=70

and 6x+100=70

and k=6x+100

so therefore k=70

70

Step-by-step explanation:

the equation is saying: 6(-5) +100. Multiply first. when multiplying a positive by a negative, you get a negative. 6 times 5 is 30. add the negative sign, and its -30. 100+ -30, is saying, 100- -30. 100 - 30 is 70. hope this helps

The situation is defined by a linear function

The function is C(p) = 40 + 2.50p

where C(p) is the cost (y-value) and p represents the number of photos ordered

Here, we are trying to get a linear function out of the information given in the question.

Summarily, a school photo will cost $40, then a price of $2.50 per the number of photos ordered

Let the total cost of the shoot be C

Let the number of photos ordered be p

Now since it is $2.50 per photo, so the cost for p photos will be $2.50 * p = $2.50p

The total cost of the shoot including the cost for p photos will now be;

C = 40 + 2.5p

where the total cost is dependent on the number of photos ordered

The above equation is the linear function.

Hence, Yes , the situation is defined by a linear function

To graph the function, we use the cost C on the y-axis, while the number of photos p will be on the x-axis

To get different values of C, we need different values for p. So to graph the function, we need to select varying value of the number of photos P

Answer:

-1.52

Step-by-step explanation:

-2+0.48=-1.52

Austin's rate of motion is (1/70)π Radians per second.

To determine Austin's rate of motion in radians per second, we need to use the formula for angular velocity:

ω = Δθ / Δt

Where:

ω = angular velocity (in radians per second)

Δθ = change in angular displacement (in radians)

Δt = change in time (in seconds)

We know that Austin runs three-quarters of a circular track, which means he covers an arc length that is equal to three-quarters of the circumference of the circle. Let's call the radius of the circle "r". Then, the arc length covered by Austin is given by:

s = (3/4) * 2πr

s = (3/2)πr

We also know that it takes Austin 1 minute and 45 seconds to cover this distance. This is the same as 105 seconds (since 1 minute = 60 seconds).

So, Δt = 105 seconds

Now, we can calculate the change in angular displacement (Δθ). The total angle around a circle is 2π radians, so the angle covered by Austin is given by:

Δθ = (3/4) * 2π

Δθ = (3/2)π

Therefore, Austin's rate of motion (ω) in radians per second is:

ω = Δθ / Δt

ω = [(3/2)π] / 105

ω = (3/210)π

ω = (1/70)π radians per second

So, Austin's rate of motion is (1/70)π radians per second.

Approximately 7 employees took a break longer than 49 minutes.

We have,

In a box-and-whisker plot, the box represents the interquartile range (IQR), which includes the middle 50% of the data.

The line within the box represents the median.

The "whiskers" extend to the minimum and maximum values, excluding any outliers.

Given the information provided:

Median = 41

Q1 = 37

Q3 = 49

Largest = 55

Smallest = 35

Since Q3 represents the upper quartile and corresponds to the boundary for the upper 25% of the data, we can conclude that 25% of the employees took a break longer than 49 minutes.

Now,

The number of employees who took a break longer than 49 minutes can be estimated by calculating 25% of the total number of employees:

25% of 27 employees

= (25/100) x 27

= 6.75

Since we cannot have a fractional number of employees, we round up to the nearest whole number.

Therefore,

Approximately 7 employees took a break longer than 49 minutes.

Step-by-step explanation:

To find the area of the shaded area, you need to subtract the area of the circle from the area of the square. The area of the square is easy: just the square of the side length. In this case, the area is 6^2=36 square centimeters. The area of the circle is:

\(\pi r^2 = \pi (3)^2 = 9\pi \approx 28.278\)

Thus, the area of the shaded region is 36-28.278 = 7.722 square centimeters.

Answer:

The estimated age of the skull is 39118 years.

Step-by-step explanation:

The amount of the substance after t years is given by:

\(A(t) = A(0)(1-r)^t\)

In which A(0) is the initial amount, and r is the decay rate.

The half-life of carbon-14 is about 5600 years.

This means that \(A(5600) = 0.5A(0)\). We use this to find r, or 1 - r, to replace in the equation. So

\(A(t) = A(0)(1-r)^t\)

\(0.5A(0) = A(0)(1-r)^{5600}\)

\((1-r)^{5600} = 0.5\)

\(\sqrt[5600]{(1-r)^{5600}} = \sqrt[5600]{0.5}\)

\(1 - r = (0.5)^{\frac{1}{5600}}\)

\(1 - r = 0.9999\)

So

\(A(t) = A(0)(0.9999)^t\)

Only 2% of the original amount of carbon-14 remains in the burnt wood of the campfire.

This is t for which \(A(t) = 0.02A(0)\). So

\(A(t) = A(0)(0.9999)^t\)

\(0.02A(0) = A(0)(0.9999)^t\)

\((0.9999)^t = 0.02\)

\(\log{(0.9999)^t} = \log{0.02}\)

\(t\log{0.9999} = \log{0.02}\)

\(t = \frac{\log{0.02}}{\log{0.9999}}\)

\(t = 39118\)

Hey!

Let's solve this together.

5x+1 = 1+x2

Possible Answers: {5,4,3,2}

Lets start with 5.

5(5)+1 = 1+2(5)***

25+1 = 1+10

26 ≠ 11

So, 5 is NOT the answer.

Now, 4.

5(4)+1 = 1+(4)2

20+1 = 1+8

21 ≠ 9

So, 4 is NOT the answer.

Now, 3.

5(3)+1 = 1+(3)2

15+1 = 1+6

16 ≠ 7

So, 3 is NOT the answer.

Lastly, 2.

5(2)+1 = 1+(2)2

10+1 = 1+4

11 ≠ 5

So, 2 is NOT an answer.

So, the answer is: None of the above. None of them can be answers because none of them make the statement true.
