The marksobtained by a group of students in science test are 90, 49, 87, 74,80, 85, 49
Find the
a) Median
b) Mode
c) Range

4x + ax - 14 > - 24

(4 + a)x - 14 > - 24

Add both sides 14

(4 + a)x - 14 + 14 > - 24 + 14

(4 + a)x > - 10

put the given value instead of x ( x = - 2 )

(4 + a)( - 2 ) > - 10

Divide both sides by - 2

When we multiply or divide the sides of an inequality by a negative number, the direction of the inequality changes which means < changes to > , and > changes to <

(4 + a)( - 2) ÷ ( - 2 ) < - 10 ÷ ( - 2 )

(4 + a) < 5

4 + a < 5

Subtract both sides 4

4 - 4 + a < 5 - 4

a < 1

Thus the highest integer value of a is:

9514 1404 393

Answer:

   B.  3x+y=4

Step-by-step explanation:

The constant on the right is positive, so the signs of the coefficients match the signs of the respective intercepts. The graph shows both x- and y-intercepts are positive, so the equation will have positive coefficients everywhere. The appropriate choice is ...

  3x +y = 4

x = 4.4

Step-by-step explanation:

The ratios of corresponding sides are in proportion , that is

[tex]\frac{x}{11}[/tex] = [tex]\frac{4}{10}[/tex] ( cross- multiply )

10x = 44 ( divide both sides by 10 )

x = 4.4

Step-by-step explanation:

Answer

-10

Step-by-step explanation:

-8w-7=9

add 7 to both sides

-8w=16

divide by negative 8 on both sides

w=-2

w-8=-10

On simplifying,

-8w - 7 = 9

-8w = 16

w = -2

then,

= w - 8

= -2 - 8

= -10.

Answer:

y + 3 = 10/11(x + 3)

Step-by-step explanation:

Given the points (-3, -3) and (8, 7), we can use these coordinates to solve for the slope of the line using the formula:

[tex]m = \frac{y2 - y1}{x2 - x1}[/tex]

Let (x1, y1) = (-3, -3)

(x2, y2) = (8, 7)

Substitute these values into the slope formula:

[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{7 - (-3)}{8 - (-3)} = \frac{10}{11}[/tex]

Thus, slope (m) = 10/11.

Next, using the slope (m) = 10/11, and one of the given points (-3, -3), we'll substitute these values into the point-slope form:

y - y1 = m(x - x1)

Let (x1, y1) = (-3, -3)

m = 10/11

y - y1 = m(x - x1)

y - (-3) = 10/11[x - (-3)]

Simplify:

y + 3 = 10/11(x + 3) this is the point-slope form.

Answer is 68.9 m/min.

Let's convert the units. To do this, we need to cancel the original units to get the units we want. We achieve this the following way :-

[tex]2.57 \frac{mi}{hr} \times \frac{1069.34 \: m}{1 \: mi} \times \frac{1 \: hr}{60 \: min} [/tex]

[tex] =>68.9 \: \frac{m}{min} [/tex]

Therefore, 2.57 mi/hr is the same as 68.9 m/min .

A.

So it is less than 1

B.

We can change -3 to 3 or -2 to 2.

This will result in:

(a) The value of given expression "((1/4)⁻³)⁻²" is less than 1, and (b) To make value greater than 1, change second exponent to positive; to make it equal to 1, change first exponent to 0.

Part (a) : Starting from the innermost exponent, (1/4)⁻³ simplifies to 4³, which is 64.

So, ((1/4)⁻³)⁻² becomes (64)⁻², which is 1/4096. Since 1/4096 is less than 1, the value of the expression is less than 1.

Part (b) : To change the value to greater than 1:

Change the second exponent to a positive value, making it ((1/4)⁻³)²,

This simplifies to (4³)², which is 4096.

To change the value to equal 1:

Change the first exponent to 0, making it ((1/4)⁰)⁻². This simplifies to (1)⁻², which is 1.

Answer:

Radius = 6

Step-by-step explanation:

The volume of a cone is V= pi*r^2*h/3

In this case, h=18 in.

Volume= 216pi in^3

So all you need to do is plug in and solve.

216pi = pi*r^2 *6

36=r^2

r=6

Radius of cone is 6 in.

A cone is a shape created by connecting all the points of a circular base (which does not contain the apex) to a common point known as the apex or vertex using a series of line segments or lines.

Given that;

Volume of cone =  216π in³

Height = 18 in

Since we know that,

The volume of a cone is V= πr²h/3

Therefore plug the values,

⇒216π = πr²(18)/3

⇒    36 = r²

⇒       r = 6 in
