The approximate probability that both you and your friend will choose chocolate ice cream from seven different flavors is 1/49, or approximately 0.020408.

We are looking to find the probability that both you and your friend choose chocolate ice cream from a selection of 7 different flavors. Since the choice of ice cream is independent for each person, we can calculate the probability of both events occurring by multiplying the probability of each event occurring individually.

The probability that one person chooses chocolate ice cream is 1 out of 7, or approximately 0.142857. To find the probability that both you and your friend choose chocolate ice cream, we multiply the individual probabilities:

Probability of you choosing chocolate: 1/7

Probability of your friend choosing chocolate: 1/7

Combined probability: 1/7 x 1/7 = 1/49

Therefore, the approximate probability that both you and your friend choose chocolate ice cream is 1/49, or approximately 0.020408.

Step-by-step explanation:

11+11+6+6+5=39

ANSWER

44 inches

EXPLANATION

The perimeter is the distance around the figure.

The unknown vertical height of the shape is 11-6=5 in.

The unknown horizontal width of the shape is 11-6=5 in.

Adding all the distance gives the perimeter.

The perimeter is

[tex]11 + 6 + 5 + 5 + 6 + 11 = 44in.[/tex]

Therefore the perimeter of the shape is 44 inches.

Answer:

1 + 1.58i , 1 - 1.58i

Step-by-step explanation:

2x^2=4x-7

2x^2 - 4x + 7 = 0

x = [-(-4) +/- sqrt((-4)^2 - 4 * 2 * 7 )] / 2*2

= [ 4 +/- sqrt (16 - 56)] / 4

= [4 +/- sqrt (-40) ] / 4

= 1 +/- 6.32i / 4

= 1 + 1.58i  and 1 - 1.58i  (answer).

Answer:

[tex]\boxed{x = 1 \pm i\sqrt{\frac{5}{ 2}} }\\[/tex]

Step-by-step explanation:

2x² - 4x + 7 =0

a = 2; b = -4; c = 7

[tex]y =\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\[/tex]

[tex]=\frac{4\pm\sqrt{(-2)^2-4\times2\times7}}{2\times2}\\[/tex]

[tex]= 1 \pm\frac{\sqrt{16-56}}{4}\\[/tex]

[tex]= 1 \pm\frac{\sqrt{-40}}{4}\\[/tex]

[tex]= 1 \pm\frac{2i\sqrt{10}}{4}\\[/tex]

[tex]= 1 \pm\frac{i\sqrt{10}}{2}\\[/tex]

[tex]= 1 \pm i\sqrt{\frac{10}{4}}\\[/tex]

[tex]\boxed{= 1 \pm i\sqrt{\frac{5}{ 2}} }\\[/tex]

The graph of y = 2x² - 4x + 7 has a minimum at (1, 5). It never touches the x-axis, so both roots are imaginary.

The side length of the triangle are as follows:

a = 11.71 and b = 15.56

The side of a triangle can be found using sine rule or cosine rule depending on the sides and angles given in a triangle.

Therefore, the sides a and b can be found in the triangle using sine rule as follows:

a / sin A = b / sin B = c / sin C

b / sin 110 = 7 / sin 25°

cross multiply

b sin 25 = 7 sin 110°

b = 7 sin 110° / sin 25

b = 6.5778483455 / 0.42261826174

b = 15.5625174507

b = 15.56 units

Let's find a as follows:

a / sin 45 = 7 / sin 25

a sin 25 = 7 sin 45

a = 7 sin 45 / sin 25

a = 4.94974746831 / 0.42261826174

a = 11.7108376716

a = 11.71 units

Answer: First option.

Step-by-step explanation:

 To simplify the polynomial [tex]2x^2y + 8x^3 - xy^2 - 2x^3 + 3xy^2 + 6y^3[/tex] you need to add the like terms, then you get:

[tex]=2x^2y+6x^3+2xy^2+6y^3[/tex]

Now, you know that Raj put this polynomial in standard form with the last term being 6y³, this means that he ordered it in descending order of "x" power and in ascending order of "y" power:

Answer:

Step-by-step explanation:

Add  1  to both sides of the equation :

                     7x2 = 1

Divide both sides of the equation by 7:

                    x2 = 1/7 = 0.143

When two things are equal, their square roots are equal. Taking the square root of the two sides of the equation we get:

Answer:

Step-by-step explanation:

Rewrite 7x^2 + 1 = 0 as 7x^2 = - 1, and then as x^2 = -1/7.

Taking the square root of both sides, and remembering that the square root of a negative number is imaginary, we get:

Answer:

Frequency is the number of times that roll occurred.

Answer:

x = - 7, x = 5

Step-by-step explanation:

To find the zeros equate f(x) to zero, that is

x² + 2x - 35 = 0

To factorise the quadratic

Consider the factors of the constant term (- 35) which sum to give the coefficient of the x- term (+ 2)

The factors are + 7 and - 5, since

7 × - 5 = 35 and 7 - 5 = + 2, hence

(x + 7)(x - 5) = 0

Equate each factor to zero and solve for x

x + 7 = 0 ⇒ x = - 7

x - 5 = 0 ⇒ x = 5

ANSWER

[tex]x = - 7 \: or \: x = 5[/tex]

EXPLANATION

The given function is

[tex]f(x) = {x}^{2} + 2x - 35[/tex]

To find the zeros, we equate the function to zero.

[tex] {x}^{2} + 2x - 35 = 0[/tex]

Split the middle term to obtain,

[tex]{x}^{2} + 7x - 5x- 35 = 0[/tex]

Factor by grouping:

[tex]{x}(x + 7) - 5(x + 7)= 0[/tex]

[tex](x + 7)(x - 5) = 0[/tex]

[tex](x + 7) = 0 \: or \: (x - 5) = 0[/tex]

[tex]x = - 7 \: or \: x = 5[/tex]

Answer:

Mitch bought 5 buckets of wings

Step-by-step explanation:

y=# of wings

X= # of pizza

X+Y=13

X = 13 - Y

11.75X + 19.95Y = 193.75

11.75(13 - Y) + 19.95Y = 193.75

152.75 - 11.75Y + 19.95Y = 193.75

152.75 + 8.2Y = 193.75

8.2Y = 41

Y = 5

Mitch bought 5 buckets of wings

Mitch bought 5 buckets of wings for his Super Bowl party, which was determined by solving a system of equations using the given information about the total number of items purchased and the total cost.

To determine how many buckets of wings Mitch bought for his Super Bowl party, let's define a system of equations based on the information given:

Let's say p represents the number of pizzas, and w represents the number of buckets of wings. We are told that Mitch bought a total of 13 items, which gives us the equation:
p + w = 13.

We are also told that he spent a total of $193.75, with pizzas costing $11.75 each and buckets of wings costing $19.95 each. This gives us the second equation:
11.75p + 19.95w = 193.75.

To solve the system of equations, we can use substitution or elimination. One way is to solve the first equation for p (p = 13 - w) and substitute that into the second equation, leading to:
11.75(13 - w) + 19.95w = 193.75.

Simplifying the equation will allow us to find the value for w. The simplified equation is:
152.75 + 8.2w = 193.75

Subtracting 152.75 from both sides gives us
8.2w = 41,
and dividing both sides by 8.2 yields
w = 5.

Therefore, Mitch bought 5 buckets of wings for the party.

The most efficient way is the 1st option

because all you have to do is add -3y on both sides to isolate x

If you used any other variables, you would have to use division which are extra steps

Answer:

Hence, the correct option is A) The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.

Step-by-step explanation:

Consider the provided system of equation.

x - 3y = 1  and  7x + 2y = 7

Let first solve the second equation.

[tex]7x + 2y = 7[/tex]

Step 1:

Divide both the sides by 7.

[tex]x + \frac{2y}{7} = 1[/tex]

Step 2:

[tex]x = 1- \frac{2y}{7} [/tex]

It took 2 steps to isolate the the variable x.

Now again consider the system of equation.

But this time we will solve the first equation.

[tex]x - 3y = 1[/tex]

Step 1:

[tex]x = 1 + 3y[/tex]

it took only 1 step to isolate the variable as the variable x in the first equation has a coefficient of one.

Hence, the correct option is A) The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.

STEP 1: Convert interest rate of 2% per 6 months into rate per year.

Final answer:

To calculate the amount at 6% simple interest on Rs 1200 for 9 months, apply the simple interest formula. Convert time to years, calculate the interest, then add it to the principal to find the total amount due, which is Rs 1254.

Explanation:

To find the amount at 6% simple interest on Rs 1200 due in 9 months, you can use the simple interest formula:

Simple Interest =  Principal × Rate × Time

We have the Principal (P) as Rs 1200, the Rate (R) as 6% per annum (or 0.06 when expressed as a decimal), and the Time (T) as 9 months. The rate is given per annum but we have in months so, we need to convert the time to years. There are 12 months in a year, so 9 months is ⅓ or 0.75 years.

Now, let's calculate the simple interest (SI):

SI = 1200 × 0.06 × 0.75 = Rs 54

Total Amount = Principal + Simple Interest

Total Amount = 1200 + 54 = Rs 1254

Therefore, the total amount due at the end of 9 months would be Rs 1254.

To find the height of triangle

Let h be the height of triangle then we can write,

Sin 63 = h/11

h = 11 * sin 63 = 11 * 0.891 = 9.801 cm
