for the last one the answer is D

Step-by-step explanation:

Answer:

80°+65°+2x+3x=360°(sum of quadrilateral is 360)

145°+5x=360°

5x=360°-145°

5X=215°

X=215°/5°

X=43°

The required value is [tex]x=43[/tex]

Given angles are,

[tex]80^{\circ}, 65^{\circ}, 2x,3x[/tex]

As we know the sum of all angles in the quadrilateral is [tex]360^{\circ}[/tex].

Then we have the relation,

[tex]80+65+2x+3x=360\\\\145+5x=360\\5x=360-145\\5x=215\\x=43[/tex]

So, the value of the x is 43.

Answer:

36b - 45 - 18b = 9 ( 18b - 45 )

Step-by-step explanation:

36b - 45 - 18b = 9 ( _b - _ )

first combine like terms:

36b - 45 - 18b  

18b - 45

then just substitute the combined numbers into the brackets

9 ( _b - _  )

9 (18b - 45)

Answer:

9(2b-6)

Step-by-step explanation:

36b-45-18b=9

36b-18b-45-9=0

18b-54

9(2b-6) (Take 9 common from both)

Answer and Step-by-step explanation:

C. The initial height of the plant is 8.36 ft.

When you plug 0 in for x, we get the value of 8.36. When x is 0, that means that 0 weeks have gone by, thus the plant starts at a height of 8.36 feet.

D. The plant grows about 1.56 ft. each week.

We see that the number 1.56 is with the x, so for every week that goes by, the growth will be changed by 1.56, thus making the plant grow 1.56 feet each week.

The  interqurtile range is q3 - q1

Q3 is 16.5 and the q1 is 12

16.5 - 12 = 4.5

Step-by-step explanation:

Answer is 4.5

Interquartile range (IQR) :

The interquartile range shows the range in values of the central 50% of the data. To find the interquartile range, subtract the value of the lower quartile ( or 25%) from the value of the upper quartile ( or 75%).

=>  IQR = Q3 – Q1

Here,

First Arrange the data in ascending order.

11, 12, 12, 13, 14, 15, 16, 17, 18

Median = 14.

Q1 = 12 and Q3 = 16.5

IQR = Q3 - Q1 => 16.5 - 12 = 4.5

Answer:

1/ 2

Step-by-step explanation:

Given that:

Number of marbles, = 10

Number of Red marbles = 5

Number of Blue marbles = 5

Probability, p = required outcome / Total possible

Probability of picking a red marble :

Required outcome = number of red marbles = 5

Total possible outcomes = total number of marbles = 10

Hence,

Probability of picking a red marble, P(picking a red marble) = 5 / 10 = 1/2

Answer:

Step-by-step explanation:

We have the system:

y+x=3

2y+x=-5

the question asks us to solve by substitution..

Let's subtract y from both sides of the first equation

y+x=3

-y    -y

x=3-y

now, let's substitute 3-y as x into the second equation

2y+3-y=-5

combine like terms

y+3=-5

subtract 3 from both sides

y=-8

so the value of y is -8

now let's use that information to solve for x; we know that x is 3-y, so let's substitute the value of y to find x

x=3-y

x=3--8

x=11

the value of x is 11

as a point, your answer is (11,-8)

Answer: $4.50 for 45min is better.

Step-by-step explanation:

The fee per min for phone charge of $1.40 for 10 min: 1.40/10 = $0.14/min

The fee per min for phone charge of $4.50 for 45 min: 4.50/45 = $0.1/min

$0.14/ min > $0.1/min

4.50 for 45min is better.

The required probability of picking a 4 from 3 4 5 6 is 1/4.

Probability is a measure of the likelihood or chance of an event occurring. It is a mathematical concept used to quantify the chance of a particular outcome or event happening, based on the total number of possible outcomes. Probability is usually expressed as a number between 0 and 1, with 0 indicating that an event is impossible, and 1 indicating that an event is certain to occur.

Here,
There are four cards in total, with one of them being a 4. Therefore, the probability of picking a 4 is:

P(4) = number of ways to pick a 4 / total number of cards

P(4) = 1/4

So the probability of picking a 4 is 1/4.
