Step-by-step explanation:

I got it right

The total number of hits John needs over the first 10 games next year to

achieve his goal is 25.

The correct answer is option 4.

To find the total number of hits John needs over the first 10 games next year to achieve his goal, we first need to calculate his current average hits per game.

The total number of hits John made in the 10 games this year is: 2 + 3 + 0 + 1 + 3 + 2 + 4 + 0 + 2 + 3 = 20.

To find the average hits per game, we divide the total number of hits (20) by the number of games (10): 20 / 10 = 2.

Since John wants to increase his average hits per game by 0.5, his target average for the next 10 games will be 2 + 0.5 = 2.5 hits per game.

To calculate the total number of hits John needs over the next 10 games, we multiply the target average by the number of games: 2.5 hits/game * 10 games = 25 hits.

Therefore, the correct answer is option 4) 25. John needs a total of 25 hits over the first 10 games next year to achieve his goal of increasing his average hits per game by 0.5.

Answer:

61

Step-by-step explanation:

If the average of 3 different positive integers, a, b and c, is 50 then:

\(\implies \dfrac{a+b+c}{3}=50\)

If b = 30:

\(\implies \dfrac{a+30+c}{3}=50\)

\(\implies a+30+c=150\)

\(\implies a+c=120\)

If a < b < c then the least possible value of c is one more than the average of a + c.

Average of a + c:

\(\implies \dfrac{a+c}{2}=\dfrac{120}{2}\)

\(\implies \dfrac{a+c}{2}=60\)

So the least possible value of c is 60 + 1 = 61.

Step-by-step explanation:

first we do 90-11.65=78.35

then we need to find out how much money she can spend

so you do 78.35-56=22.35

so she can spend a total of 22.35 on her comic books

now you need to find out how much books she can buy with the 22.35 that she has

so the equation would be 22.35÷3.72=6

45 Distinct handshakes took place when every player shook hands with everyone who played.

To find out how many distinct handshakes took place if every player shook hands with everyone who played, we will

use the concept of combinations.

Identify the number of players involved, which is 10 (you plus 9 friends).

Use the formula for combinations: C(n, k) = n! / [k! × (n-k)!],

where n is the total number of players and k is the number of players in each handshake (which is 2).

Plug in the values: C(10, 2) = 10! / [2! × (10-2)!].

Calculate the factorial values: 10! = 3,628,800, 2! = 2, and 8! = 40,320.

Plug in the factorial values and calculate: C(10, 2) = 3,628,800 / (2 × 40,320) = 3,628,800 / 80,640 = 45.

So, 45 distinct handshakes took place when every player shook hands with everyone who played.

The value of x is 10.7 cm and an equation that finds the value of x is 4(x + 3) = 54.8. By using the perimeter of a square, the required equation is evaluated.

A square has 4 sides with equal lengths. We know that the perimeter is the total circumference of the shape. So, if the length of the square is 'a' then its perimeter is 4a.

It is given that, the length of the square a = x + 3 cm

The perimeter of the square 4a = 54.8 cm

Thus, on substituting the 'a' value into the perimeter, we get

4(x + 3) = 54.8

This is the required equation that finds the value of 'x'.

and on simplifying the obtained equation, we get

4x + 12 = 54.8

⇒ 4x = 54.8 - 12 = 42.8

∴ x = 42.8/4 = 10.7 cm

Answer:

total cost equation = ( 9+x) times 4 = 724. Total,price of a ticket is 162$

Step-by-step explanation:

Since insurance for each ticket costs 19$ and the family bought four and the ticket itself costs x, the costs of the four tickets is (19+x) times 4. If thr total cost is 724 then we can take 19 times4 and subtract that from it because 19times 4 + x times 4 is the same as (19+x) times 4. From this we fet 648. Now we have x4 or x times 4 = 648 leftover, so divided 648 by 4 to get one x out of it since it is made up of four x. You get 162 from this, so the price of a ticket without insurance is 162$

\(16x^2+25y^2-400=0\)

Step-by-step explanation:

Given:

There are 4 types of conic sections:

The definition of an ellipse is:

Therefore, the given definition is one for an ellipse.

\(\boxed{\begin{minipage}{7.4 cm}\underline{General equation of an ellipse}\\\\$\dfrac{(x-h)^2}{a^2}+\dfrac{(y-k)^2}{b^2}=1$\\\\where:\\\phantom{ww}$\bullet$ $(h,k)$ is the center. \\ \phantom{ww}$\bullet$ $(h\pm a,k)$ or $(h,k\pm b)$ are the vertices. \\ \phantom{ww}$\bullet$ $(h\pm c,k)$ or $(h,k\pm c)$ where $c^2=a^2-b^2$.\\\end{minipage}}\)

As the given foci are (-3, 0) and (3, 0), they are on the x-axis. Therefore:

Therefore, the major axis is on the x-axis and the vertices are (h±a, k) and the co-vertices are (h, k±b).

The constant is the major axis which is 2a.  Given the constant is 10:

\(\implies 2a=10\)

\(\implies a=5\)

Since c² = a² - b²:

\(\implies 3^2=5^2-b^2\)

\(\implies b^2=5^2-3^2\)

\(\implies b^2=25-9\)

\(\implies b^2=16\)

Therefore, the equation for the conic section (ellipse) is:

\(\implies \dfrac{(x-0)^2}{5^2}+\dfrac{(y-0)^2}{16}=1\)

\(\implies \dfrac{x^2}{25}+\dfrac{y^2}{16}=1\)

In standard form:

\(\implies 25 \cdot \dfrac{x^2}{25}+25 \cdot \dfrac{y^2}{16}=25 \cdot 1\)

\(\implies x^2+\dfrac{25}{16}y^2=25\)

\(\implies 16 \cdot x^2+16 \cdot \dfrac{25}{16}y^2=16 \cdot 25\)

\(\implies 16x^2+25y^2=400\)

\(\implies 16x^2+25y^2-400=400-400\)

\(\implies 16x^2+25y^2-400=0\)

The value of x that gives the critical point of the quadratic function y = ax^2 + bx + c is x = -b/(2a). The condition for the critical point to correspond to a minimum or maximum is that the leading coefficient 'a' must be non-zero, i.e., a ≠ 0.

To find the critical point of the quadratic function y = ax^2 + bx + c, we need to determine the value of x that results in a horizontal tangent line, or in other words, the vertex of the parabola.

The critical point occurs when the derivative of the function is equal to zero. Taking the derivative of y = ax^2 + bx + c with respect to x, we get:

dy/dx = 2ax + b

Setting this derivative equal to zero:

2ax + b = 0

Solving for x:

x = -b/(2a)

The critical point is thus given by x = -b/(2a).

As for the conditions on a, b, and c, the critical point exists for any values of a, b, and c. However, to ensure that the critical point corresponds to a minimum or maximum, rather than a point of inflection, the leading coefficient 'a' must be non-zero.

In other words, a ≠ 0. This condition ensures that the parabola opens upward or downward, allowing for a minimum or maximum value.

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

Explanation:

As you probably can guess (or already know), the term "slope intercept form" means that all we need are the slope and y intercept to get the equation.

To get the slope, we need two points. Pick any two points you want. I'll pick (3,-7) and (6,-9). Notice how we go down 2 units and then over to the right 3 units when we move from the first point to the second point.

See diagram below.

So the slope is rise/run = -2/3. The negative rise indicates we go down. The run is always moving to the right. This produces the downhill trend when we move from left to right.

--------------------

We can also use the slope formula. I'll use those two points mentioned earlier.

m = (y2-y1)/(x2-x1)

m = (-9-(-7))/(6-3)

m = (-9+7)/(6-3)

m = -2/3

We get the same result as earlier

--------------------

The y intercept is where the graph crosses the vertical y axis. This is at 5. So b = 5 is the y intercept.

Since the slope is m = -2/3 and the y intercept is b = 5, we go from y = mx+b to y = (-2/3)x-5 which is our final answer.

The flux of F across S is equal to 2304/5π.

Given vector field is F= 32x3 + yi + 2 (cosz + 3y3) j + 32z3k.

The surface S is the one which is bounded by the hemisphere z = - 4 - x2 - y2

and the plane z = 0.

This is a closed surface enclosing a region R which is the upper part of the solid sphere x2 + y2 + z2 = 16.

The divergence theorem states that the flux of the vector field across a closed surface is equal to the triple integral of the divergence of the vector field over the region it encloses. Hence, the flux can be calculated as follows:

S F . n d S = R (del. F) d V where n is the outward pointing unit normal vector on the surface S.

The divergence of F is given by del.

F = 96x2 + 3 + 2 (-sinz) + 96z2

Therefore, R (del . F) d

V = ∫0π/2∫0π/2∫04- r

2sinΦ (96r2cos2Θ + 96r

2sin2Φ + 3) + 2(-sin(4 + r2)) drdΘdΦ

where R is the region enclosed by the surface S.

So, we have the following equation after integrating it: R (del . F) dV = 2304/5π.

The flux of F across S is equal to 2304/5π.
