plz help!!!!!!!!!!!!!!!!!!

so I believe it is C 0.8215

The probability is 0.1785

The study of how likely certain events are to occur is known as probability. In its simplest form, it is concerned with the fall of a game's cards or the roll of a dice. However, probability is also essential to life and science as a whole. Probability is used, for example, in weather forecasting and figuring out how much your insurance premiums will cost.

Given probability of tail by spinning a coin is 65% = 0.65

p(t) = 0.65 and p(h) = 0.35

where h= head and t= tail

coin spins 4 time

p(t) for first time = 0.65

p(t) for second time = 0.65 x 0.65 =0.4225  

p(t) for third time = 0.65 x0.65 x 0.65 = 0.274

p(t) for fourth time = 0.65 x 0.65 x0.65 x 0.65 = 0.178

Hence probability that a student who spins 4 pennies will have them all land tails is 0.178

Answer:

K

Step-by-step explanation:

Answer:

1) 3x = 39  ; x = 39/3 = 13

2) x + 7 = 15 ; x = 15-7 = 8

3) 6x = 18  ; x = 18/6 = 3

4) x-4 = 11  ; x = 11 + 4 = 15

5) 1/7 x = 3   ;  x = 3 *7 = 21

6) 13+x = 21  ;  x = 21 - 13 = 8

I hope im right!!!

Answer: {-7, -6}

Explanation: When an equation has a squared term in it,

it's called a polynomial equation.

The rule for solving a polynomial equation

is to first set it equal to 0, then factor.

Since this equation is already set equal to 0, we can factor the left side.

The left side is a trinomial that can be

factored as the product of two binomials.

The first term in each binomial will be a factor of the w².

Since w² factors a w · w, we use a w as our first term.

For the last terms, we use factors of 42 that add

to 13 and these factors are +7 and +6.

So we have (w + 7)(w + 6) = 0.

So either w + 7 = 0 or w + 6 = 0.

Solving for w in each equation, we find that our solution set is {-7, -6}.

Answer:

m<1=61

m<2=40

m<3=60

m<4=80

m<5=100

Step-by-step explanation:

180/3=60

180/9=20

20x2=40

20x4=80

20x3=60

59+60=119

180-119=61

180-80=100

Answer:

B (Y, N, N)

Step-by-step explanation:

a) y = 1/3x, so each value satisfies it. This is true.

b) If "a" is "Y" then b has to be no

c) 1 * 11 = 11

2 * 2 = 22

3 * 5 = 15

The last equation does not follow the rules for the previous two equations, so it is no.

Thus, the answer is B (Y, N, N)

3x + 18 = 48

Bringing like terms on one side

3x = 48 - 18

3x = 30

x = 30/10

x = 3

Answer:

x = 10

Step-by-step explanation:

Subtract 18 from both sides.

3x=48-18

Simplify  48-18 to 30.

3x=30

Divide both sides by 3.

x= 30/3

Simplify  30/3\ to 10

x=10

x=10

It's not in a quadrant

The horizontal line (----) is the x-axis and the vertical line ( | ) is the y- axis

these split the graph into 4 parts, called quadrants.

They're usually labelled in roman numerals (I, II, III, IV)

Quadrant I is the top right

they're labelled counter-clockwise from there so

Quadrant II is the top left

Quadrant III is the bottom left and

Answer:

number 2 is c

number 1 is d?

Step-by-step explanation:

because if it a has been 1 minute(m=1) the 35(1)=w --> w=35 for for one minute there is 35  words 35m=w

for 1 i cannot see, but if d says 3/4 and x=3/4 then d is the answer

Answer:

(For your second question.):

35w=m

Step-by-step explanation:

Why?

It states in the problem itself that miles types 35 words per minute.

"w" stands for words

'm' stands for minutes.

The constant rate relies on the clearest data after all. The equation itself is enough!

Remember: 1 min = 60 seconds.

Answer:

Output value = 20

Step-by-step explanation:

Graph of any function is made up of two values → Values on x axis and Values along y axis.

x values represent the input values and y values represents the output values.

For every x value there is a y value because of which the data set is called to a function.

In other words, a function can't have two output values for a single input value.

If the input value of function is = 10

Then for x = 10, out value (along y axis) will be = 20

Therefore, Output value of the given function is 20.

Step-by-step explanation:

because u have to math ight

Given:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

To find:

The probability of drawing a quarter, replacing it, and drawing another quarter.

Solution:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

Total number of coins = 8+5+1+7 = 21

Probability of getting a quarter is

[tex]P(Quarter)=\dfrac{\text{Number of quarters}}{\text{Total number of coins}}[/tex]

[tex]P(Quarter)=\dfrac{7}{21}[/tex]

[tex]P(Quarter)=\dfrac{1}{3}[/tex]

After drawing a quarter, we replaced it. So, the probability of getting quarter in second draw is the same and first one, .i.e., [tex]P(Quarter)=\dfrac{1}{3}[/tex].

The probability of drawing a quarter, replacing it, and drawing another quarter is

[tex]P=\dfrac{1}{3}\times \dfrac{1}{3}[/tex]

[tex]P=\dfrac{1}{9}[/tex]

Therefore, the required probability is [tex]\dfrac{1}{9}[/tex].
