can you find the exact circumference of a circle when you multipy the diameter by 22/7? explain

Answer:

See explanation below.

Step-by-step explanation:

Let's take P as the proportion of new candidates between 30 years and 50 years

A) The null and alternative hypotheses:

H0 : p = 0.5

H1: p < 0.5

b) Type I error, is an error whereby the null hypothesis, H0 is rejected although it is true. Here, the type I error will be to conclude that there was age discrimination in the hiring process, whereas it was fair and random.

ie, H0: p = 0.5, then H0 is rejected.

When the baseball is thrown upward from the top of a 448-ft-tall building with an initial velocity of 96 feet per second, the height after 2 seconds is 576 feet.

It should be noted that the baseball is thrown upward from the top of a 448-ft-tall building with an initial velocity of 96 feet per second. The height, ℎ, of the baseball above the ground seconds after being thrown is given by the function ℎ() = −16t² + 96t + 448.

Therefore, the height after 2 seconds will be:

= -16(2)² + 96(2) + 448

= 576 feet

The batting average and percentage hits for the players will be Albert Pujois= 0.356 and 35.6%, Stan Musial=0.376 and 37.6% and Rogers Honsby=0.402 and 40.2%.

What is average?

In Maths, an average of a list of data is the expression of the central value of a set of data. Mathematically, it is defined as the ratio of summation of all the data to the number of units present in the list. In terms of statistics, the average of a given set of numerical data is also called mean. For example, the average of 2, 3 and 4 is (2+3+4)/3 = 9/3 =3. So here 3 is the central value of 2,3 and 4.  Thus, the meaning of average is to find the mean value of a group of numbers.

Average = Sum of Values/Number of Values

Also

Suppose, we have given with n number of values such as x1, x2, x3 ,….., xn. The average or the mean of the given data will be equal to:

Average = (x1+x2+x3+…+xn)/n

Now,

The batting averages and percentage of hits/bats for the players will be

Albert Pujois=187/524=0.356 and 35.6%

Stan Musial=230/611=0.376 and 37.6%

Rogers Honsby=203/504=0.402 and 40.2%

So I will put these in the order 1.Rogers Honsby 2.Stan Musial 3.Albert Pujois.

The probability of the baseball player getting exactly 4 hits out of 10 times at bat is approximately 0.161, or 16.1%.

To calculate the probability of a baseball player getting exactly 4 hits out of 10 times he was up at bat, we need to use the binomial probability formula.

The binomial probability formula is given by:P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

Where:

P(X = k) is the probability of getting exactly k hits

n is the total number of trials (in this case, the player's 10 times at bat)

k is the number of successful trials (in this case, 4 hits)

p is the probability of success in a single trial (in this case, the player's batting average, 0.298)

(1 - p) is the probability of failure in a single trial

Plugging in the values:

P(X = 4) = C(10, 4) * (0.298)^4 * (1 - 0.298)^(10 - 4)

Using the combination formula C(n, k) = n! / (k! * (n - k)!):

P(X = 4) = 10! / (4! * (10 - 4)!) * (0.298)^4 * (1 - 0.298)^(10 - 4)

Calculating the values:

P(X = 4) ≈ 0.161

The researcher can anticipate that 2.28 per cent of the children in their study will consume less sugar than 40 grammes every day.

According to its definition, a percentage is any number relative to 100. It is shown with the sign %. "Out of 100" is what the percentage means. Consider dividing any quantity or item into 100 identical bits.

To find the percentage of children in the study who had a decrease in their sugar intake to below 40 grams per day, we need to determine the proportion of children whose sugar intake is below 40g.

We can use the standard normal distribution and the z-score formula to find this proportion:

z = (40 - 50) / 5 = -2

Using a standard normal distribution table, we can find that the proportion of children with a sugar intake below 40g is approximately 0.0228 or 2.28%.

Therefore, the researcher can expect that approximately 2.28% of children in their study will have a sugar intake below 40 grams per day with the new behavioural method.

Answer:

1/3>2/5

Step-by-step explanation:

The value of A(2,2) is not 4, but rather 65536, which is obtained by using the recursive definition of the function.

The given inductive definition of Ackermann's function is used to calculate the values of the function for given input values of m and n. The definition uses recursive steps to define the function for different values of m and n. To find the value of A(2,2), we start with the base cases, which are given by the first two lines of the definition. Here, since m=2 and n=2, we use the third line of the definition, which gives the value 2n=2x2=4. Now, we use the fourth line of the definition to compute A(2,1) by using the value of A(2,2) that we just found. This gives us A(2,1)=\(2^4\)=16. Finally, we use the fourth line of the definition once again to compute A(2,0) by using the value of A(2,1) that we just found. This gives us A(2,0)=\(2^{16}\)=65536. Therefore, the value of A(2,2) is not 4, but rather 65536, which is obtained by using the recursive definition of the function.

Step-by-step explanation:

Given that :

Standard deviation (s) = 2km

Error in estimation is within 0.4 km ; Error (E) = 0.4 km

Using the relation :

Sample size = ((Zα/2 * s) /E)^2

Using α = 0.05

The Zcritical at 0.05 = Z0.025 = 1.96

Sample size = ((1.96 * 2) / 0.4)^2

The variance of Billy's grades obtained from his test scores is 15.76

The variance is a measure of variability or spread a dataset. The variance can be calculated from the sum of the square of the differences of the data points from the mean divided by the number or count of the data points.

The variance of Billy's test scores can be calculated by finding the mean or the average of the scores, then finding the sum of the squares of the differences of each score from the mean as follows;

The mean score = (89 + 88 + 93 + 90 + 81)/5 = 88.2

The square of the differences of the values from the mean can be calculated as follows;

(89 - 88.2)² = 0.64, (88 - 88.2)² = 0.04, (93 - 88.2)² = 23.04, (90 - 88.2)² = 3.24, and (81 - 88.2)² = 51.84

The sum of the square of the differences is therefore;

0.64 + 0.04 + 23.04 + 3.24 + 51.84 = 78.8

The variable that represents this would be both Quantitative and Discrete. This is because since this variable is measuring the amount of days it has a value type which therefore makes it a Quantative variable. Also, since the number of days that mankind has waled the Earth is a finite value, regardless of how large it may be, it would be considered to be a discrete variable. Continuous variables would be something along the lines of "What is the size of the Universe?" because the value of this variable would be neverending since we cannot calculate it.

Step-by-step explanation:

The length in each circle is:

(a) CD = 19.5 units

(b) UZ = 12.8 units

(a) The Intersecting Secant-Tangent Theorem states that "if two secant lines intersect outside a circle, and a tangent line is drawn from the point of intersection to the circle, then the product of the lengths of the two secant segments is equal to the square of the length of the tangent segment".

Using the theorem, we have:

EC * ED = EG²

6.5 * ED = 13²

6.5ED = 169

ED = 169/6.5

ED = 26 units

ED = EC + CD

26 = 6.5 + CD

CD = 26 - 6.5

CD = 19.5 units

(b) The Secant-Secant Theorem states that "if two secant segments which share an endpoint outside of the circle, the product of one secant segment and its external segment is equal to the product of the other secant segment and its external segment".

Using the theorem above, we can say:

UZ * UW = UX * UY

UZ * 40 = 8 * 64

40UZ = 512

UZ = 512/40

UZ = 12.8 units

(Here, D means a defective battery, and N means a nondefective battery.)

b. The number of outcomes in the sample space is infinite, as the experiment could potentially continue indefinitely. However, in practice, we can define a maximum number of batteries that could be examined before the experiment is stopped.

c. The event E, that the number of batteries examined is a number, would include outcomes where the experiment stopped at a particular number of batteries. For example, if the experiment stopped after examining three batteries (i.e., the fourth battery was nondefective), then the outcome would be DDDN, and it would be included in event E. However, outcomes where the experiment continued indefinitely (e.g., DDDDD...) would not be included in event E.

The equations x² + 4x + 3 = 0 and x² -6x + 13 = 0 are equivalent to (x + 2)² = 1 and (x - 3)² = -4

An equation is an expression that shows the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on

The standard equation of a quadratic function is:

y = ax² + bx + c

1) Given that:

x² + 4x + 3 = 0

subtract 3 from both sides:

x² + 4x = -3

add to both sides the square of half the coefficient of x:

x² + 4x + 4 = -3 + 4

(x + 2)² = 1

2) Given that:

x² - 6x + 13 = 0

subtract 13 from both sides:

x² - 6x = -13

add to both sides the square of half the coefficient of x:

x² - 6x + 9 = -13 + 9

(x - 3)² = -4
