Femi's mean score is C. 77

Femi's mean score is the sum of all his bowling scores, divided by the number of times he bowled.

Question said that he bowled 5 times so the mean is:

= (68 + 75 + 72 + 90 + 80) / 5

= 385 / 5

= 77

Femi's mean score is therefore 77

Answer:

Median

Step-by-step explanation:

The measure of central tendency is used to represent an entire group of data with a common single  number. There are three types of measure of central tendency, the mean , the median and the mode. Our focus here is on the median because in any skewed dataset, The median is the best form for a skewed type of distribution. The median is the middle number in an ordered set of data.

In a skewed type of distribution, the mode is the highest  point of the distribution. In the measure of central tendency, the mean is mostly influenced by the outliers and it is pulled towards  to the tail region of the distribution.

You subtract because she had a negative profit for week two and/or a profit below 0.

GIVEN :

a = 1/√10 ( 3i + k) and

b = 1/7 ( 2i + 3j - 6k)

TO FIND :

( 2a- b) . [ ( a x b ) x ( a + 2b)]

SOLUTION :

◆Going with the equation given,

( 2a - b) . [ ( a x b ) x ( a + 2b)]

= (2a - b) [( a×b×a) + 2(a×b)×b]

◆BAC - CAB RULE,

A×B×C = B( A.B ) - C(A.B )

= (2a- b ) [ (b (a.a ) - a (a.b ) + 2b ( a.b) -2b (a.b]

Solving further

= (2a - b )(b - 2a)

= -4a.a -b.b

=-5.

Answer:

y = 3 cos(π/5 x) + 5

Step-by-step explanation:

The amplitude is half the difference of the min and max.

A = (8 − 2) / 2

A = 3

The midline is the average of the min and max.

C = (8 + 2) / 2

C = 5

The difference in the x values of the min and max is half the period.

T/2 = 5 − 0

T = 10

The function is a maximum at x = 0, so use cosine.

y = 3 cos(2π/10 x) + 5

y = 3 cos(π/5 x) + 5

The formula of the function, where x is entered in radians is [tex]\rm y = 3 sin(\dfrac{\pi}{5}x) + 5[/tex] and this can be determined by using the given data.

Given :

The graph of a sinusoidal function has a maximum point at (0,8) and then has a minimum point at (5,2).

The following steps can be used in order to determine the formula of the function, where x is entered in radians:

Step 1 - The generalized sinusoidal function is given below:

[tex]\rm y = A sin(bx) + C[/tex]

where A is the amplitude.

Step 2 - Now, the value of A is given below:

[tex]\rm A = \dfrac{8-2}{2}[/tex]

A = 3

Step 3 - The value of C is calculated as:

[tex]\rm C = \dfrac{8+2}{2}[/tex]

C = 5

Step 4 - The time period is calculated as:

[tex]\rm \dfrac{T}{2}=5-0[/tex]

T = 10

Step 5 - So, the value of y is maximum at (x = 0).

[tex]\rm y = 3 sin(\dfrac{2\pi}{10}x) + 5[/tex]

[tex]\rm y = 3 sin(\dfrac{\pi}{5}x) + 5[/tex]

Answer:

Step-by-step explanation:

Given that each zodiac sign occupies 1/12 of a year.

Then the minimum number of persons for Y[all different signs] < 0.5,

The probability of at least two having the same sign is 1 minus the probability of all having different signs.

This can be represented as A [at least 2 person share the same sign] = 1 - Y[all different signs] must be > 0.5

Therefore we have 1 - 12/12 *11/12 * 10/12 *9/12 *8/12 = 0.38

This implies that the lowest number will be found to be 5

Hence, the correct answer is 5.

Answer:

1. 49/150

2. 107/300

Step-by-step explanation:

Here is a probability question.

a. The first question asks us to find the probability of getting more than 4.

Now to do this, we look at our possible results when we roll the die, we can see that we can have 1-6.

But within this range, only two numbers are greater than 4, these are 5 and 6

Thus, to calculate the probability of getting either 5 or 6, we look at their frequencies, sum it up, then divide by the total number of times which the die was rolled.

The frequency of 5 is 47, while that of 6 is 51

The probability of getting more than 4 = Probability of getting 5 + Probability of getting 6 = (Frequency of 5 + Frequency of 6)/Total number of trials

= (47 + 51)/300 = 98/300 = 49/150

b. Probability of getting less than 3

Here, we proceed as we did in the first question. The numbers which are less than 3 are 1 and 2.

So the probability of getting less than 3 = Probability of getting 1 + Probability of getting 2 = (Frequency of 1 + Frequency of 2)/Total number of trials

Frequency of 1 = 62 while Frequency of 2 = 45

So, probability of getting less than 3 = (45 + 62)/300 = 107/300

Answer:

The two iterations of f(x) = 1.5598

Step-by-step explanation:

If we apply  Newton's iterations method, we get a new guess of a zero of a function, f(x), xₙ₊₁, using a previous guess of, xₙ.

xₙ₊₁ = xₙ - f(xₙ) / f'(xₙ)

Given;

f(xₙ) = cos x, then  f'(xₙ) = - sin x

cos x / - sin x = -cot x

substitute in "-cot x" into the equation

xₙ₊₁ = xₙ - (- cot x)

xₙ₊₁ = xₙ + cot x

x₁ = 0.7

first iteration

x₂ = 0.7 + cot (0.7)

x₂ =  0.7 + 1.18724

x₂ = 1.88724

second iteration

x₃ = 1.88724 + cot (1.88724)

x₃ = 1.88724 - 0.32744

x₃ = 1.5598

To four decimal places = 1.5598

Answer:

Step-by-step explanation:

Step 1

We have to first find the area of the circular sign.

Since the sign is circular in shape, we use the Area of Circle.

Area of a Circle = πr²

r = 1.5 feet

π = 3.14

Area of a Circle = 3.14 × 1.5²

= 7.065ft² or 7.065 square feet.

Step 2

We find out how much it cost to print the circular sign.

We are told in the question that

The printing company charges $29 per square foot

Hence,

1 square foot = $29

7.065 square feet =

Cross multiply

= 7.065 × $29

=$ 204.885

Approximately to the nearest cent, $204.89

Therefore, it will cost $204.89 to print the circular sign
