Part B: what is the probability of picking a blue ball from the bag?
Part C What is the probability of picking a yellow ball and then a blue ball after
replacement? Determine if the two events are independent events.

Answer:

Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3

7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~

Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little weird, just plug (7/3) in for z and you will get 4, trust me

what is the probability that the third spinner lands on a perfect square or a gray space?

6/12 or 1/2

Answer:

There are 6 gray spaces (12, 2, 4, 6, 8, 10) and 3 perfect squares (4, 9, 1). However, 4 is repetitive (it is gray and a perfect square) so there are only 8 we want. There are 12 numbers/spaces in total. The probability formula is (# of desired outcomes)/(# of total outcomes). In this case, there are 8 desired outcomes and 12 total outcomes. So, our answer is 8/12, or 2/3.

Answer:

D) 55.8

Step-by-step explanation:

Answer:

a=62

Step-by-step explanation:

11a + 9c=2482 equation 1

a + c = 262 equation 2

a=262-c isolate value of a in equation

11(262-c) + 9c = 2482 substitute value of a (262-c) into equation 2

2882-11c + 9c= 2482 solve

-2c=-400

c=200

a+c=262

a+200=262

a=62

Check answer:

11a + 9c=2482

11(62)+9(200)=2482

682+1800=2482

2482=2482

Answer:

See the proof below

Step-by-step explanation:

prove that 1-cosA/sinA=cosecA-cotA​

Starting from RHS

cosecA-cotA​

From trig identty

cosec theta = 1/sintheta and cot theta = cos theta/sin theta

Hence;

cosecA-cotA​

= 1/sinA - cosA/sinA

FInd the LCM

= 1-cosA/sinA (LHS)

Step-by-step explanation:

The median is the line in the center of the box

Answer:

y = x + 3

Step-by-step explanation:

Equation of the line can be written as y = mx + b (slope-intercept form)

Let's find the slope (m) and the y-intercept (b)

Slope (m) = change in y/change in x

Using two points on the line, (0, 3) and (1, 4),

Slope (m) = (4 - 3)/(1 - 0) = 1/1

m = 1

y-intercept (b) = 3 (the coordinate of the point where the y-axis is intercepted by ye line)

To write the equation, substitute m = 1 and b = 3 into y = mx + b

y = 1(x) + 3

y = x + 3

Answer:

4th option

Step-by-step explanation:

[tex]\frac{n}{360}[/tex] represents the fraction of the circle occupied by the sector , that is

The ratio of degrees in the sector's central angle to the total number of degrees in the circle

Option 4 is correct. The ratio of degrees in the sector's central angle to the total number of degrees in the circle.

Fraction is defined as the number of composition constitute the Whole.

area of a sector is a secotor = n/360 degrees pie r^2
n =number of fraction at which the circle is divided
mean n = in degrees x number of angles.
and the ratio n/360 degrees
describes the number of partition to the circle.

Thus, the ratio n/360 degrees defines The ratio of degrees in the sector's central angle to the total number of degrees in the circle.

Answer:

yes,

distance = time * speed

the more hours you spend in the road, the longer distance you took

Step-by-step explanation:

Answer:

Yes, the relationship between hours elapsed x and distance traveled y represent a proportional relationship.

Step-by-step explanation:

This is because he continuously stayed at a constant speed and didn't change. Once you stay at a constant speed then it will always be a proportional relationship.

Answer:

  70 square units

Step-by-step explanation:

The overall outline is 15 units wide and 8 units high, for an area of ...

  A = WH

  A = (15 units)(8 units) = 120 units²

__

The white space taken out of that overall area is 5 units high and 15-4-1 = 10 units wide. The area of the white space is ...

  A = (5 units)(10 units) = 50 units²

__

The shaded area is the difference between the overall area and the white space taken out:

  shaded = 120 units² -50 units² = 70 units²

Answer:

The solution is 4 >/= -21

4 is greater than or equal to negative 21

Step-by-step explanation:

7x + 4 >/= 7(x - 3)

We'll start by distributing the y7 to the items in parentheses

7x + 4 >/= 7x - 21

Subtract 7x from both sides

4 >/= -21

Answer:

B. The graph would shift 5 units up.

Step-by-step explanation:

Before the change:

Before the change, the function was given by:

[tex]y = x^2 - 3[/tex]

After the change:

After the change, the function was given by:

[tex]y = x^2 + 2[/tex]

Considering the function as it was before the change, it can also be written as:

[tex]y = x^2 - 3 + 5[/tex]

Which means that 5 was added to the function, and when a number n is added to a function, there function is shifted n units up. So the correct answer to this problem is given by option B.

Answer:

We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.

Step-by-step explanation:

Given :

City n x s

A 26 $4.05 $0.55

B 32 $5.15 $0.85

H0 : μ1 - μ2 = 0

H0 : μ1 - μ2 ≠ 0

n1 = 26 ; x1 = 4.05 ; s1 = 0.55

n2 = 32 ; x2 = 5.15 ; s2 = 0.85

Tstatistic :

(x1 - x2) / √(s1²/n1 + s2²/n2)

(4.05 - 5.15) / √(0.55²/26 + 0.85²/32)

-1.1 / 0.1849668

= - 5.947

Using the smaller n;

df = n - 1 ; 26 - 1 = 25

Pvalue = (-5.947, 24)

Pvalue = 0.000001

Since Pvalue < α ; We reject the Null and conclude that the mean costs of a meal at fast food restaurants in two different cities are different.
