Answer:

Associative property

Step-by-step explanation:

Given

½ + ⅔ + 3/2

Required

What reason supports Winona's process?

This question could be better answered, if supported with options; however, since there's none, I'll provide my answer on a general rule.

Winona's process can be supported by associative property of algebra which implies that

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

So, when Winona added ½ to 3/2, it is represented by a + c

And when she added the result to ⅔, it is represented by (a + c) + b

Hence, we can conclude that Winona applied associative property

Answer:

1,280

Step-by-step explanation:

prob(spots) = 12/180 = 1/15

so of the 1200 frogs, (1/15)(1200) should have spots, so ..

how many should not have frogs ?

or

prob(not spots) = 14/15

number who don't have spots = (14/15)(1200) = 1,280

Answer:

2

0.9

Step-by-step explanation:

The average age of the lizards will be 2 and the standard deviation is 0.81.

Average is defined as the ratio of the sum of the number of the data sets to the total number of the data. The standard deviation is a statistic that expresses how much variation or dispersion there is in a set of values.

Given that the lizards were randomly selected from the 36 lizards at your local zoo: 1, 2, 2, 1, 3, 3

The average will be calculated as:-

Average = Sum of the data / Number of the data

Average = ( 1 + 2 + 1 + 3 + 3 ) / 6 = 12 / 6 = 2

The standard deviation will be calculated as:-

[tex]\rm \sigma=\sqrt{\dfrac{\sum(x-\mu)^2}{N}}\\\\\sigma=\sqrt{\dfrac{(1-2)^2+(2-2)^2+(1-2)^2+(3-2)^2+(3-2)^2}6[/tex]

[tex]\sigma[/tex] = 0.81

Therefore, the average age of the lizards will be 2 and the standard deviation is 0.81.

Answer:

a) E = I(R+r)

b) r = (E/I) - R

Step-by-step explanation:

Answer:

P_he = 562.5 mmHg

P_ne = 1068.75 mmHg

P_ar = 618.75 mmHg

Step-by-step explanation:

Formula for partial pressure is;

Partial pressure = mole fraction × total pressure

Mole fraction of Helium(He); x_he= 1/(1 + 1.9 + 1.1) = 1/4 = 0.25

Mole fraction of Neon(Ne); x_ne = 1.9/(1 + 1.9 + 1.1) = 1.9/4 = 0.475

Mole fraction of argon; x_ar = 1.1/(1 + 1.9 + 1.1) = 1.1/4 = 0.275

Thus;

Partial pressure of He;

P_he = 0.25 × 2250

P_he = 562.5 mmHg

Partial pressure of Ne;

P_ne = 0.475 × 2250

P_ne = 1068.75 mmHg

Partial pressure of Ar;

P_ar = 0.275 × 2250

P_ar = 618.75 mmHg

I'm not really sure what the question is here, because you just gave a statement... but if you are trying to get an expression from words, here is what it would be:

A = 10N

I'm also not sure if "a number" is equal to the same as "a number" at the end, but I'm guessing not. If it is though, and you're trying to find the value of A, the answer would be:

A = 10

Answer:

s = independent variable, P(s) = dependent variable

Step-by-step explanation:

s = discrete because you need a certain value for shirts. For instance, 1,2,3, etc... you cannot make profit off half a shirt or a quarter of a shirt.

P(s) = continuous because profits doesnt have to be an exact value. For instance, you can make a profit of $12.65

Answer:

10$

Step-by-step explanation:

i think is 1 dollars because if u multiply 25 by 40% it will give you ur answer wait till someone else answers

Ashley got $10 discount, at 40% discount on the meal worth $25.

Percentage is a part of the whole number. It is denoted by % sign.

1 %= 1/100.

Given that,

The cost of meal = $25.00

The discount given to Ashley on meal = 40%

The total value of discount = 25 x 40/100

                                             = 1000/100

                                             = 10

The total discount given by shopkeeper is $10.

Tip Total: $ 12

Total (Bill + Tip): $ 92

Sorry if this is wrong

Step-by-step explanation:

Answer:

$12 tip

Step-by-step explanation:

For this problem let's first round our bill amount to the nearest ten dollars.  So $79.42 becomes $80.00.  From here we will simply need to find 15% of $80.00 which can be found simply through multiplication as follows:

$80.00 * 0.15 = ?

$80.00 * 0.15 = 12

So, we can say the estimated 15% tip for the bill is $12.

2c+10=30

2c+10−10=30−10

2c=20

2c÷2=20÷2

Answer: c=10

Answer:

10

Step-by-step explanation:

2c + 10 = 30

so we take 10 to the other side to become - 10.

Therefore 2c = 30 - 10

= 20

Divide both sides by the coefficient of c that's 2

2c = 20

c = 10

Answer:

The answer would be $40.

Step-by-step explanation:

You take the first 25% off and add it to the other 25% off, which would equal 50% off. After that you take 50% off for $80, which would be $40 because half of $80 is $40.

Answer:

The height of the prism is 5 inches

Step-by-step explanation:

The rule of the lateral area of the rectangular prism is

L.A = 2(L + W) × H, where

∵ A rectangular prism has a length of 9 inches and a width of 8 inches

∴ L = 9 inches

∴ W = 8 inches

∵ The lateral area of it is 170 square inches

∴ L.A = 170 square inches

→ Substitute them in the rule above to find the height of the prism

∵ 170 = 2(9 + 8) × H

∴ 170 = 2(17) × 5

∴ 170 = 34 × H

→ Divide both sides by 34 to find H

∴ 5 = H

∴ The height of the prism is 5 inches.

Answer:

At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0

Step-by-step explanation:

At midnight, the temperature was 43.7°F. In the morning, the temperature was −3.6°F.

We can say that −3.6 lie on the LHS of a number line while 43.7 lie on RHS of the number line and 0 at the mid.

43.7°F is above 0 and 3.6°F is below 0.

At midnight, the temperature was 43.7 degrees above 0, and in the morning, it was 3.6 degrees below 0 . Hence, the correct option is (d).

Problem 1

f(x) = x + 1/x

f(1) = 1 + 1/1

f(1) = 1 + 1

f(1) = 2

Answer: 2

============================================

Problem 2

(f o f)(1) = f( f(1) )

(f o f)(1) = f( 2 )

(f o f)(1) = 2 + 1/2

(f o f)(1) = 4/2 + 1/2

(f o f)(1) = 5/2

Answer:  5/2

============================================

Problem 3

(f o f o f)(1) = f(  f(f(1)) )

(f o f o f)(1) = f(  (f o f)(1) )

(f o f o f)(1) = f(  5/2 )

(f o f o f)(1) = 5/2 + 1/(5/2)

(f o f o f)(1) = 5/2 + 2/5

(f o f o f)(1) = 25/10 + 4/10

(f o f o f)(1) = 29/10

Answer: 29/10

============================================

Problem 4

(f o f o f o f)(1) = f(   f(f(f(1))   )

(f o f o f o f)(1) = f(   (f o f o f)(1)    )

(f o f o f o f)(1) = f(   29/10   )

(f o f o f o f)(1) = 29/10 + 1/(29/10)

(f o f o f o f)(1) = 29/10 + 10/29

(f o f o f o f)(1) = 841/290 + 100/290

(f o f o f o f)(1) = 941/290

Answer: 941/290

============================================

Problem 5

(f o f o f o f o f)(1) = f(   f(f(f(f(1))))   )

(f o f o f o f o f)(1) = f(   (f o f o f o f)(1)  )

(f o f o f o f o f)(1) = f(   941/290  )

(f o f o f o f o f)(1) = 941/290 + 1/(941/290)

(f o f o f o f o f)(1) = 941/290 + 290/941

(f o f o f o f o f)(1) = 885481/272890 + 84100/272890

(f o f o f o f o f)(1) = 969581/272890

Answer: 969581/272890

A function assigns the values. The value of (f•f•f•f•f)(1)​ is 969581/272890.

A function assigns the value of each element of one set to the other specific element of another set.

1.)

The value of f(1) for the given function f(x) =x+1/x can be calculated as shown below,

f(x) = x + 1/x

f(1) = 1 + 1/1

    = 1 + 1

    = 2

2.)

(f · f)(1) = f( f(1) )

Since the value of f(1)=2, therefore, it can be rewritten as,

(f · f)(1) = f(2)

           = 2 + 1/2

           = 4/2 + 1/2

           = 5/2

3.)

(f · f · f)(1) = f(  f(f(1)) )

Since the value of f(f(1))=5/2, therefore, it can be rewritten as,

(f · f · f)(1) = f(  (f·f)(1) )

              = f(  5/2 )

              = 5/2 + 1/(5/2)

              = 5/2 + 2/5

              = 25/10 + 4/10

              = 29/10

4.)

(f · f · f · f)(1) = f(  f(f(f(1))  )

Since the value of f(f(f(1)))=29/10, therefore, it can be rewritten as,

(f · f · f · f)(1) = f(   (f·f·f)(1)    )

                  = f( 29/10 )

                  = 29/10 + 1/(29/10)

                  = 29/10 + 10/29

                  = 841/290 + 100/290

                  = 941/290

5.)

(f · f · f · f · f)(1) = f(   f(f(f(f(1))))   )

Since the value of f(f(f(1)))=29/10, therefore, it can be rewritten as,

(f o f o f o f o f)(1) = f(   (f·f·f·f)(1)  )

                           = f(  941/290 )

                           = 941/290 + 1/(941/290)

                           = 941/290 + 290/941

                           = 885481/272890 + 84100/272890

                           = 969581/272890

Hence, the value of (f•f•f•f•f)(1)​ is 969581/272890.
