The probability Matt will choose pepperoni pizza and Ashley will choose a salad is 1/4.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

There is a 75% chance Matt will choose pepperoni pizza

= 75/ 100

= 3/4

and, Ashley chooses a salad which had a chance = 1/3.

As, the events are independent then we know that if two events A and B are independent evets then

P(a B)= P(A) . P(B).

so, the probability is

= 1/3 x 3/4

= 1/4

The widest confidence interval that will be produced the 99.7%, given a sample proportion of 0.4.

If the sample size is given to be n < 30, then for finding the confidence interval for the mean of the population from this small sample, we use the t-statistic.

Let the sample mean given as [tex]\overline{x}[/tex] and

The sample standard deviation s, and

The sample size = n, and

The level of significance = [tex]\alpha[/tex]

Then, we get the confidence interval in between the limits

[tex]\overline{x} \pm t_{\alpha/2}\times \dfrac{s}{\sqrt{n}}[/tex]

where [tex]t_{\alpha/2}[/tex] is the critical value of 't' that can be found online or from tabulated values of critical value for a specific level of significance and degree of freedom n - 1.

In statistics, a confidence interval is a range to estimate for unknown terms. The most common level is the 95% confidence interval.

So, the widest confidence interval that will be produced the 99.7%, given a sample proportion of 0.4.

Answer: Hi your questions some required details attached below is the required random number table and missing question

Answer : 83, 58, 64, 26, 47, 68, 29, 4, 78

Step-by-step explanation:

The number of 9 faculty members that will be included in the sample will be written considering the fact that the 9 numbers ( first 9 ) are lesser than 88, and also considering the fact that 58 is repeated twice ( in the random number table ). Hence The number of 9 faculty members = 83, 58, 64, 26, 47, 68, 29, 4, 78

Step-by-step explanation:

Using the graph, we pick a convenient point: (20, 180)

This point means that for 20 hours of work, Vincent is paid 180 dollars. In fraction form, we can write 20hrs/180 dollars. If we simplify the fraction by dividing both the numerator and denominator by 20 we get 1/9 AKA 1hr/9 dollars. So in 1 hour, Vinnie is paid $9.00

Area of rectangle = 408 in²

Length = 3x-2 and width = x

The area of a rectangle is given by :

A = lb

(3x-2)x = 408

x = 12 inch and x = -11.33 in

Neglecting negative value,

The width of rectangle = 12 inch

The length of rectangle = 3x-2 = 3(12)-2 = 34 inch

Base of triangle = 2x+2

Height = x

The area of a triangle is given by :

[tex]A=\dfrac{1}{2}bh\\\\600=\dfrac{1}{2}\times (2x+2)x\\\\600=(x+1)x[/tex]

x = 24 cm and x = -25 cm

Neglecting negative value, x = 24 cm

Base = 2x+2 = 2(24)+2 = 50 cm

Hence, this is the required solution.

Answer: [tex]1.4\times 10^{-6}[/tex]

Step-by-step explanation:

Given

The wavelength of light is 0.0000014 inches

Here, seven digits are followed by a decimal point

To convert it to scientific notation, convert it into a fraction i.e.

[tex]=0.0000014=\dfrac{14}{10,000,000}[/tex]

In the denominator, there are 7 zeroes

[tex]\therefore 0.0000014=\dfrac{14}{10^7}\\\\\Rightarrow 0.0000014=14\times 10^{-7}\\\\\Rightarrow 0.0000014=1.4\times 10^{-6}[/tex]

Answer:

(a) PR = 55.2 cm

(b) RT = 19.7 cm

(c) <RPT = [tex]20.8^{o}[/tex]

Step-by-step explanation:

(a) to determine the value of PR, apply the Pythagoras theorem to PQR.

PQ = 45, and SP = QR = 32. So that;

[tex]/hyp/^{2}[/tex] = [tex]/Adj 1/^{2}[/tex] + [tex]/Adj 2/^{2}[/tex]

[tex]/PR/^{2}[/tex] = [tex]45^{2}[/tex] + [tex]32^{2}[/tex]

          = 2025 + 1024

          = 3049

PR = [tex]\sqrt{3049}[/tex]

     = 55.218

PR = 55.2 cm

(b) To determine RT, apply the appropriate trigonometric function to QRT.

Let RT be represented by x, so that;

Sin [tex]38^{o}[/tex] = [tex]\frac{x}{32}[/tex]

x = 32 * Sin [tex]38^{o}[/tex]

  = 32 * 0.6157

x = 19.7024

RT = 19.7 cm

(c) To determine <RPT, let the angle be represented by θ.

Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]

        = [tex]\frac{RT}{PR}[/tex]

Sin θ = [tex]\frac{19.7024}{55.218}[/tex]

         = 0.3568

θ = [tex]Sin^{-1}[/tex] 0.35568

  = [tex]20.84^{o}[/tex]

Thus, <RPT = [tex]20.8^{o}[/tex]

Answer:

Slope = 27/11

AB = 29.15 u

Step-by-step explanation:

Given :-

To Find :-

We can find the slope of the line passing through the points [tex]( x_1,y_1)[/tex] and [tex]( x_2,y_2)[/tex]as ,

[tex]\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}[/tex]

[tex]\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}[/tex]

Hence the slope of the line is 27/11 .

[tex]\rule{200}2[/tex]

Finding the length of AB :-

[tex]\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }[/tex]

Hence the length of AB is 29.15 units .

Answer:

[tex]\angle U = 20^\circ[/tex]

Step-by-step explanation:

Given

See attachment

[tex]\angle S = 23[/tex]

arc [tex]RS = 86[/tex]

Required

Find [tex]\angle U[/tex]

Let

[tex]O \to[/tex] center of the circle

We have that:

arc [tex]RS = 86[/tex]

This implies that:

[tex]\angle SOR = 86^\circ[/tex]

and

[tex]\triangle SOR \to[/tex] is an isosceles triangle

because:

[tex]SO = OR \to[/tex] the radius of the circle

And

[tex]\angle RSO = \angle ORS[/tex]

So, we have:

[tex]\angle RSO + \angle ORS + \angle SOR = 180^\circ[/tex] --- angles in a triangle

[tex]\angle RSO + \angle ORS + 86^\circ = 180^\circ[/tex]

Collect like terms

[tex]\angle RSO + \angle ORS =- 86^\circ + 180^\circ[/tex]

[tex]\angle RSO + \angle ORS =94^\circ[/tex]

Recall that: [tex]\angle RSO = \angle ORS[/tex]

So:

[tex]\angle RSO + \angle RSO =94^\circ[/tex]

[tex]2\angle RSO =94^\circ[/tex]

Divide by 2

[tex]\angle RSO =47^\circ[/tex]

RU is a tangent.

So:

[tex]\angle ORU = 90^\circ[/tex]

Given that:

[tex]\angle S = 23[/tex]

Considering [tex]\triangle SRU[/tex]

We have:

[tex]\angle RSU = \angle S = 23^\circ[/tex]

So:

[tex]\angle SRU= \angle RSO + \angle ORU[/tex]

[tex]\angle SRU= 47 + 90[/tex]

[tex]\angle SRU= 137[/tex]

Lastly:

[tex]\angle RUS + \angle RSU + \angle SRU =180^{0}[/tex]

[tex]\angle RUS + 23 + 137=180^{0}[/tex]

Collect like terms

[tex]\angle RUS =180^{0} - 23 - 137[/tex]

[tex]\angle RUS =20^{0}[/tex]

Hence:

[tex]\angle U = 20^\circ[/tex]
