can someone help me on this?

Answer:

a) 30% probability that it will not be colder today than it was yesterday

b) 90% probability that it will not be warmer today than it was yesterday

Step-by-step explanation:

In this question, we have that:

0.1 = 10% probability it will be warmer today than yesterday.

0.7 = 70% probability it will be colder today than yesterday.

a .What is the probability that it will not be colder today than it was yesterday?

70% probability it will be colder, so 100 - 70 = 30% probability that it will not be colder today than it was yesterday.

b What is the probability that it will not be warmer today than it was yesterday?

10% probability it will be warmer today than yesterday, so 100 - 10 = 90% probability that it will not be warmer today than it was yesterday

Answer:

15: Yes, no, yes, yes, no; 16A: C = ($0.29)X + ($1.45)Y + ($2.50)Z; 16B: Yes

Step-by-step explanation:

For question 15: We need to multiply the widths and lengths given to see if they equal the area we are trying to achieve. Therefore, some of them work, and some do not.

For question 16:

Part A: We'll set a variable for the number of each supply she can buy. Pencils will be represented by X, pens by Y and Notebooks by Z, and we'll represent total cost by C. The total cost will therefore be represented by C = ($0.29)X + ($1.45)Y + ($2.50)Z.

Part B: We'll plug the numbers of items she wants to buy into our formula and see if it comes out to less than $20. So in this case C = ($0.29)(3) + ($1.45)(4) + ($2.50)(2). Therefore, C = $11.67, which is less than $20, so she can afford her school supplies.

Answer:

Sin 2 (30)°=  [tex]\frac{\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Explanation:-

Given that   Sin 2 (30)°

we know that the formula  sin2θ = 2sinθ cosθ

   Given that θ = 30°

   Now  

         sin2(30)° = 2sin30° cos30°

                                             [tex]= 2 ( \frac{1}{2} X \frac{\sqrt{3} }{2} )[/tex]

       After cancellation, we get

                           Sin 2 (30)° = [tex]\frac{\sqrt{3} }{2}[/tex]

Final answer:-

          Sin 2 (30)° = [tex]\frac{\sqrt{3} }{2}[/tex]    

Answer:

A rational number can expressed as a whole number, integer, square root, fraction, and more as long as it's not imaginary. However, the number has to be clean like 1/2=0.5, 1/3=0.333, -1, 200. If it is a number that goes on forever and is not repeated like 1.22222, then it's an irrational number like pie-3.14159..., 5/0, 2.201845. If you have an imaginary number- 6i, then this would be considered as non real numbers like x+2, red, wind, and y/7.

Answer:

- 1

Step-by-step explanation:

( x + 4 )² + 38 = 47

( x + 4 )² = 47 - 38

( x + 4 )² = 9

( x + 4 )² = 3²

Square root on both sides,

x + 4 = 3

x = 3 - 4

x = - 1

Answer:

The equation of the line is x = 2

Answer:

x = 2

Step-by-step explanation:

When you are given a straight line whether it's horizontal or vertical on a graph and is told to write it as an equation,

it can be a horizontal line, y = the number the line is on from the y-axis

or a vertical line, x = the number the line is on from the x-axis.

In this case you have a vertical line so the equation would be

x = the number the line is on from the x-axis, which is 2 so your final answer would be

x = 2

Answer:

25

Step-by-step explanation:

All the data values from least to greatest:

20, 23, 23, 25, 25, 27, 27, 27, 28

Since the data values are odd, the middle value is the median:

25

From what i understand from the picture is there is a right angle triangle given with the hypotenes being 37, base being 12 and the perpendicular is 35.

we need to determine the value or Cos x

Easy way to remember which value to out where is

sinx=p/h -----> some people have

cosx=b/h ----> curly brown hair

tanx=p/b -----> through proper brushing

learned this is 8th grade in collage right now still comes in handy

we need cosx so we will use the second formula

[tex]cosx=\frac{b}{h} \\\cosx=\frac{12}{37} \\x= cosx^{-1} (\frac{12}{37})\\[/tex]

which can then be simplified using a calculator

x= 71.1 degree

for this question from what i understand is the answer is cos x = cos (12/37)

Answer:

Step-by-step explanation:

G. A. B. O

By probability in the chart, it goes from most to least that is grapes, apples, bananas and oranges

[tex] {3x}^{2} - 5x = - 8 \\ {3x}^{2} - 5x + 8 = 0[/tex]

This equation has the next form:

[tex] {ax}^{2} + bx + c = 0[/tex]

To find if the equation has two complex solutions we have to check if the discriminant is negative, as follows:

[tex] {b}^{2} - 4ac \\ ( { - 5})^{2} - 4 \: . \: 3 \: . \: 8 = 25 - 96 = - 71 < 0[/tex]

Then, the first case has two complex solutions.

In the second case,

[tex] {2x}^{2} = 6x - 5 \\ {2x}^{2} - 6x + 5 = 0[/tex]

The discriminant in this case is:

[tex]( { - 6})^{2} - 4 \: . \: 2 \: . \: 5 = 36 - 40 = - 4 < 0[/tex]

Then, the second case has two complex solutions.

In the third case,

[tex]12x = {9x}^{2} + 4 \\ { - 9x}^{2} + 12x - 4 = 0[/tex]

The discriminant in this case is:

[tex] {12}^{2} - 4 \: . \: ( - 9) \: . \: ( - 4) = 144 - 144 = 0[/tex]

Then, the third case has two real solutions.

In the fourth case,

[tex] { - x}^{2} - 10x = 34 \\ { - x}^{2} - 10x - 34 = 0[/tex]

The discriminant in this case is:

[tex]( { - 10})^{2} - 4 \: . \: ( - 1) \: . \: ( - 34) = 100 - 136 = - 36 < 0[/tex]

Then, the fourth case has two complex solutions.
