Trigonometric functions examine the interaction between the dimensions and angles of a triangular form.

Mamadou notices an airplane arriving in a straight line and flying directly overhead on the radar. The plane stays at the same height of 7325 feet. Mamadou initially measures a 15-degree angle of inclination to the plane at point A. Later, he detects a 42-degree angle of elevation to the plane at point B.

The distance between points A and B will be given as,

D = 7325 / tan 15° - 7325 / tan 42°

D = 27337.27 - 8135.34

Answer:

So the probability of this happening is exactly 1 - it must be true

Step-by-step explanation:

If we calculate modulo(5) for each of the six numbers (the integer remainder after dividing by 5), we will get six values from 0 to 4.

By the pigeonhole principle, since there are 6 numbers and only 5 possible values, at least two must share the same value modulo 5. Pick two of those, say x and y, in which case x mod 5 = y mod 5, therefore (x - y) mod 5 = 0. In other words, their difference is a multiple of 5.

So the probability of this happening is exactly 1 - it must be true

The mean and standard deviation are given as 6 and 0.48 respectively.

According to the question The Population Mean number of strikes per square kilometer (μ) = 6 and the Population standard deviation of strikes per square kilometer (σ) = 2.4. The Sample size is equal to (n) = 16. We know that the sample mean number of strikes per square kilometer (m) = mean Number of strikes per square kilometer in the population. From this observation it is clear that the mean will be equal to

μ = m = 6

So, the Sample mean = 5

Now, the Standard deviation = standard error = σ/√n. Now we get

Standard Error = 2.4 / √25

Standard Error = 2.4 / 5

Standard Error = 0.48

the factors of 48 are

1 , 2, 3, 4, 6, 8, 12, 16 , 24 , 48

the factor pairs are

1 × 48 , 2 × 24 , 3 × 16 , 4 × 12 , 6 × 8

We can infer that we have sufficient evidence to reject the null hypothesis and that the true mean is significantly lower than 6.7 at 10% of significance if we compare the p value and the significance level given =0.05 and observe that p'.

Hypothesis test: A statistical hypothesis test is a technique for determining if the available data are sufficient to support a specific hypothesis. We can make probabilistic claims regarding population parameters thanks to hypothesis testing.

Data are provided and noted.

X=6.8 display the sample mean

σ= 0.9 show the population's standard deviation.

n= 280 samples taken

μο=6.7 the value that we wish to test should be represented

α=0.1 signify the hypothesis test's level of significance.

The stat would be represented as z. (variable of interest)

p' indicate the test's p value (variable of interest)

Name the prevailing and competing hypothesis

The system of hypothesis must be tested to see if the true mean is below the criteria.

Null hypothesis:  μ ≥ 6.7

Alternative hypothesis: μ < 6.7

Applying a z test to compare the actual mean to the reference value is preferable if the sample size is greater than 30 and we are aware of the population variation. The statistic is given by:

z=(X-μο)/σ[tex]\sqrt{n}[/tex]  ......(1)

z-test: "enables the comparison of group means. One of the most widely used tests, it is used to determine whether the mean is (higher, lower, or not equal) to a given value ".

Calculate the statistic

We can replace in formula (1) the info given like this:

z=(6.8-6.7)/0.9[tex]\sqrt{280}[/tex]

P-value

Since is a one sided test the p value would be:

p'=p(z<0.0066)

We can infer that we have sufficient evidence to reject the null hypothesis and that the true mean is considerably lower than 6.7 at 10% of significance if we compare the p value and the significance level given =0.1 and observe that p'.

The image of the function after it is vertically stretched is f'(x) = 4|x + 3|

The function is given as

f(x) = |x + 3|

The transformation is given as

Vertical stretch by a factor of 4

This implies that we stretch the function f(x) by a factor of 4

This transformation is represented mathematically as

(x, y) = (x, 4y)

So, we have

f'(x) = 4 * f(x)

So, we have the following equation

f'(x) = 4 * (|x + 3|)

Remove the bracket

So, we have

f'(x) = 4 * |x + 3|

Evaluate the products

So, we have

f'(x) = 4|x + 3|

Hence, the equation of f'(x) is f'(x) = 4|x + 3|

Also, he scored 65 out of 70 on an assignment. Expressing his score in the assignment in terms of percentage, it becomes

65/70 x 100 = 92.86%

We would find the average between the two percentages

Average = sum of percentages/number of percentages

Average = (89.29 + 92.86)/2

the data are normally distributed with a mean of 74.674.6 hours and a standard deviation of 9.19.1 hours. So  10.2% of gadgets were powered by batteries for fewer than 63 hours.

Given that,

Data have a mean of 74.6 hours and a standard deviation of 9.1 hours, and they are regularly distributed.

The standard deviation is defined as ?

The standard deviation is a metric that reveals how much variance from the mean there is, including spread, dispersion, and spread. A "typical" variation from the mean is shown by the standard deviation. Because it uses the data set's original units of measurement, it is a well-liked measure of variability.

[tex]p(X\leq 63) = p(Z\leq 63-74.6/9.1)[/tex]

From standard deviation,

         [tex]p(X\leq 63) = p(Z\leq -1.279)= 0.1061[/tex]

a certain percentage of gadgets have battery life of less than 63 hours.

X= 63 hours

Percentage of devices ran on the batteries for fewer than 63 hours = 10.2%

Therefore, 10.2% of electronic devices had battery life of less than 63 hours

Step-by-step explanation:

I assume, based on what I see, that the solid line is just cos(x), right ?

and we need to find the equation that draws the dotted line, correct ?

the notation is strange, as it seems we need to find a multiplication factor for x in the cos function.

but there is no multiplication factor that moves the cosine wave by pi to the left or to the right (so that the max. happens, where originally the minimum happens, and vice versa).

so, we need to add (or subtract) pi in the cosine function.

the rest is clear :

the normal distance between min. and max. of the cosine function is 2 (between +1 and -1). the target is 4. so we need to multiply by 2.

and since the values of that function have to be between -4 and 0 (instead of -2 and +2), we have to subtract overall 2.

giving us the function :

y = 2×cos(pi + x) + -2

However, there is no way to further simplify.

hypothenuse = AC

B) To find the length AB, we will use the value of AC just obtained to get it

since triangle ABC is a right-angled triangle, we will use Pythagoras theorem

so that

|AC|^2 = |AB|^2 +|BC|^2

AC = 5.8332cm

BC = 4cm

|AB|^2 = |AC|^2 - |BC|^2

C) The perimeter of the quadrilateral can be found by adding the length of all the sides around its edges.

Perimeter = AD +CD + BC + AB

We do not have CD and we must find CD

Perimeter of ABCD = 5 + 3.004366195 + 4 +4.245729883 = 16.25009708cm
