Step-by-step explanation:

12.72

The probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.

The likelihood or chance of an event occurring is measured by probability. Usually, it is stated as a number between 0 and 1, where 0 denotes an event's impossibility and 1 denotes its certainty.

There are 10 balls in total, and 2 of them are basketballs. So the number of balls that are not basketballs is 10 - 2 = 8.

Of these 8 balls, we know that 1 is a softball. So the number of balls that are either a softball or not a basketball is 1 + 8 = 9.

Therefore, the probability of grabbing a ball that is either a softball or not a basketball is:

P(softball or not a basketball) = 9/10

So the probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.

Answer:

first, second and fourth

Step-by-step explanation:

If you use distribution,

6a(5+d) is the same as  

6a(5) + 6a(d)

Multiplied =  30a + 6ad

So it's the 1st 2nd and fourth choice.

1st is stated above when multiplied out and combined.

2nd is after distribution.

4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.

It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.

It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)

Answer:

(6a*5) + (6a*d)

30a + 6ad

30a + (6a*d)

Answer:

The general solution of the given differential equation

[tex]y = ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]

Step-by-step explanation:

Step(I):-

Given differential equation

                                   y⁴+18y"+81y=0

                         ⇒    (D⁴+18D²+81)y =0

The auxiliary equation

                               [tex]m^4+18m^2+81 =0[/tex]

                              [tex](m^2)^{2} + 2 (9) m^{2} +(9)^2 = 0[/tex]

        we will use formula  ( a + b)² = a² + 2 a b + b²    

                  ⇒    ( m² + 9 ) ² = 0

                   ⇒    ( m² + 9 ) ( m² + 9 ) = 0

                      [tex]m^{2} =-9\\m= - 3i and m=3i[/tex]

            m² + 9 = 0      

      [tex]m² = -9\\m= -3i and m=3i[/tex]

The complex roots are   0± 3 i ,0 ± 3 i

Step(ii):-

The complementary function  

              [tex]y = e^{\alpha x } ( c_{1} + c_{2} x ) cos\beta x + ( c_{3} +c_{4} x) sin\beta x[/tex]

The general solution of the given differential equation

          [tex]y = e^{0 x } ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]

The general solution of the given differential equation

   [tex]y = ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]

Answer:

14 sq. mi.

Step-by-step explanation:

Based on the scale we can see that for every inch there are an actual 4 miles in the town. Therefore, this is 4 times the model version meaning that if the model's area is calculated as 3.5 square inches then we can multiply this by 4 to get the actual area of the town.

3.5 sq. in. * 4 = 14 sq. miles

Finally, we can see that the area of the town is 14 sq. mi.

Answer:

x = 0.84375

Step-by-step explanation:

-13 - 4x - 13x = 14 + 15x

-13 - 17x = 14 + 15x

-13 - 17x + 17x = 14 + 15x + 17x

-13 = 14 + 32x

-13 - 14 = 32x

-27 = 32x

-27 / -32 = 32x / 32

0.84375 = x

Answer:

135.58 just did this

Step-by-step explanation:

First, I calculated the amount of money he got on Monday. I multiplied. 8.50 x 7 which equals 59.50. Then, I calculated the amount of money he got on Tuesday. I multiplied 8.50 (since that is the number of money he gets paid) to 3.2 (since that’s the amount of hours he works). I got 27.200. Then lastly, I calculated the amount of money he got on Friday. So first I changed 5 3/4 into a decimal. This is 5.75. After, I multiplied 8.50 x 5.75, and got 48.8750.lastly, I added and got 135.575. So if you round it, it will be 135.58

Answer:

Michelle needs to pay $88.56 to pay for her purchase, including tax.

Step-by-step explanation:

The purchasing cost of a pair of jeans = $35

The purchasing cost of dress = $47

The total purchase cost = $35 + $47

                                        = $82

Given that the store charges 8% sales tax on all purchases.

Thus,

Tax amount  = 8% × 82

                      = 8/100 × 82

                      = 0.08 × 82

                      = 6.56

The total cost including the tax = Tax amount + The total purchase cost

                                                    = 6.56 + 82

                                                    = $88.56

Therefore, Michelle needs to pay $88.56 to pay for her purchase, including tax.

Answer:

The answer is "[tex]10 \% ,\text{upper limit}=52,\ and \ \text{lower limit}=28[/tex]"

Step-by-step explanation:

Given value:

[tex]\mu =40\\\\\sigma=4[/tex]

In point a:

Calculating the value of the coefficient of variation:

[tex]\to C.V= \frac{6}{\mu} \times 100 \%\\\\ \to C.V= \frac{4}{\mu} \times 100 \% \\\\ \to C.V = 10 \%[/tex]

In point B:

when  88.9 \% of the value are lies then  :

[tex]\to \mu \pm 36\\\\\to \mu -36 = 40-3\times 4 = 40 -12 =28\\\\\to \mu +36 = 40+3\times 4 = 40 +12 =52[/tex]

[tex]\text{upper limit}=52\\\\\text{lower limit}=28[/tex]
