Answer:

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Step-by-step explanation:

Given

[tex]S = \{1,2,3,4,5\}[/tex]

[tex]n(S) = 5[/tex]

Required

[tex]P(x > 1\ and\ x < 2)[/tex]

[tex]P(x > 1\ and\ x < 2)[/tex] is calculated as:

[tex]P(x > 1\ and\ x < 2) = P(x > 1) * P(x < 2)[/tex]

Since it is a probability with replacement, we have:

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

For x > 1, we have:

[tex]x > 1 = \{2,3,4,5\}\\[/tex]

[tex]n(x > 1) = 4[/tex]

For x < 2, we have:

[tex]x < 2 = \{1\}[/tex]

[tex]n(x < 2) = 1[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{n(x > 1)}{n(S)} * \frac{n(x < 2)}{n(S)}[/tex]

becomes

[tex]P(x > 1\ and\ x < 2) = \frac{4}{5} * \frac{1}{5}[/tex]

[tex]P(x > 1\ and\ x < 2) = \frac{4}{25}[/tex]

Answer:

Well..They gave you the hint all you have to do is apply the formula

hint: the way a quadratic formula is written is [tex]ax^2 + bx + c[/tex]

So lets do this

axis of symmetry = [tex]\frac{-b}{2a} = \frac{-(-12)}{2(-3)} = \frac{12}{-6} = -2 = x[/tex]

Answer:

Step-by-step explanation:

-2÷1 = -2

4÷(-2) = -2

-8:4 = -2

So this is a geometric sequence with a common ratio of -2

Therefore:

the 5th term:   -8×(-2) = 16

the 6th term:   16×(-2) = -32

Answer:

area = 82 cm²

Step-by-step explanation:

The figure comprises a trapezoid, a triangle and a square.

Calculating areas of the three shapes separately and then adding them will give us the required area of the composite figure.

Area of square : (side)²

= (2)²

= 4 cm²

Area of triangle : ½ × b × h

= ½ × 3 × 12

= 3 × 6

= 18 cm²

Area of trapezoid : ½ × (a + b) × h

= ½ × (5+5) × 12

= ½ × 10 × 12

= 5 × 12

= 60 cm²

Now, area of the composite figure :

= 4 + 18 + 60

= 22 + 60

= 82 cm²

Answer:

Step-by-step explanation:

If you exclude the square on the bottom, you have a trapezoid with bases of 5 cm and 8 cm and the height of 12 cm.

Its area is:

Add the area of the square with sides of 2 cm:

Total area is:

Step-by-step explanation:

Given

The question is incomplete, as the required stem-and-leaf plot is not available. I will answer this question with the attached plot

Required

Drivers that travel below 80 mph

A stem and leaf plot has the following syntax: Stem | Leaves

Take for instance:

7 | 2 3 4 7

The above represents 72, 73, 74 and 77

Using the above illustration, the attached leaf plot can be interpreted as:

60, 61, 61, 65, 66, 66, 67

71, 73, 76, 77, 78

80 81... and so on

The drivers that drive below 80 mph are:

60, 61, 61, 65, 66, 66, 67

71, 73, 76, 77, 78

And the frequency is: 12

Hence, 12 drivers travel below 80 mph (using the attached stem and leaf plot)

Answer:

26x+25

Step-by-step explanation:

not sure if this an answer choice but here

Let's simplify step-by-step.

19x+18+7+4x+3x

Combine Like Terms:

=19x+18+7+4x+3x

=(19x+4x+3x)+(18+7)

=26x+25

Answer:

=26x+25

Answer:

a + (b + c) = (a + b) + c

Step-by-step explanation:

a= (-12), b = 4, c = (-25)

[tex](12) + (4 + ( - 25)) = ( - 12 + 4) + ( - 25) \\ - 33 = - 33[/tex]

Answer:

GIVEN :-

TO VERIFY :-

SOLUTION :-

Find the values of L.H.S. & R.H.S.

L.H.S. :-

Put all values in → [tex]\boxed{a+(b+c)}[/tex]

⇒ -12 + [4 + (-25)]

⇒ -12 + (4 - 25)

⇒ -12 + (-21)

⇒ -12 - 21

⇒ -33

R.H.S. :-

Put all values in → [tex]\boxed{(a+b)+c}[/tex]

⇒ (-12 + 4) + (-25)

⇒ -8 - 25

⇒ -33

CONCLUSION :-

L.H.S. = R.H.S.

⇒ a + (b + c) = (a + b) + c

Answer:

Measure of obtuse angle is 134 degrees

Step-by-step explanation:

these two angles are supplementary so they add up to 180

68x-2 +23x=180

91x-2=180

91x = 182

x = 2

plug in x

68 (2) -2 = 134

23 (x) = 46

Option D :- (180 - 2x)°

Answer:

11.28 units squared

Step-by-step explanation:

Area of a circle is

[tex]\pi {r}^{2} [/tex]

each square has an area of 1

There are four semi-circles, which make two complete circles.

the area of the 5 squares plus the area of the two circles equals the total area.

5 + 2(3.14) = 11.28

Answer:

SA =12.

Step-by-step explanation:

In a parallelogram the diagonals bisect each other , so:

2x - 1 = x + 7

2x - x = 7 + 1

x = 8.

QS = x + 4 = 8 + 4

= 12.

But QS = SA, so SA =12.
