Answer:

f x 7 + 10

Step-by-step explanation:

When it says multiply f and 7 and add 10 that does not mean solve but for instance lets say the letter f is 5 so it would be 5 x 7 + 10

Answer:

15.22

Step-by-step explanation:

The equation of the circumference of a circle is 2(pi)r

This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)

so a simple formula is:

arc length in radians X radius

radius = 4 cm

the area that the question wants is the oposite

of the 142 degree section so 360 - 142 = 218

218 degrees *  (pi/180) = 3.80482 rad

3.80482 * 4 = 15.21928 cm

Answer:

268

Step-by-step explanation:

Answer:

The number that goes in the box is 268

Step-by-step explanation:

Equations

We are given an incomplete identity:

___ + 308 - 126 = 450

And it's required to fill the space with the number that makes the identity true.

Let's fill the space with a variable x:

x + 308 - 126 = 450

Solving for x implies doing inverse operations as shown on the left side.

We must add 126 and subtract 308:

x = 450 + 126 - 308

x = 268

The number that goes in the box is 268

Answer:

g(-2) = -19, g(0) = -5 and g(3) = -14

Step-by-step explanation:

The given function is :

[tex]g(x) = -2x^2 + 3x - 5[/tex] ...(1)

We need to find the function when x = -2,0 and 3.

Put x = -2 in equation (1).

[tex]g(-2) = -2(-2)^2 + 3(-2) - 5\\\\=-19[/tex]

Put x = 0 in equation (1).

[tex]g(0) = -2(0)^2 + 3(0) - 5\\\\=-5[/tex]

Put x = 3 in equation (1).

[tex]g(3) = -2(3)^2 + 3(3) - 5\\\\=-14[/tex]

Hence, g(-2) = -19, g(0) = -5 and g(3) = -14

Answer:

0.40

Step-by-step explanation:

Change the divisor 1.8 to a whole number by moving the decimal point 1 places to the right. Then move the decimal point in the dividend the same, 1 places to the right.

We then have the equations:

7.2 ÷ 18 = 0.40

and therefore:

0.72 ÷ 1.8 = 0.40

Both calculated to 2 decimal places.

The correct statement is,

⇒ The finding is significant at both α = 0.05 and α = 0.01.

The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.

Given that;

For a hypothesis test of H₀, p = 0.35 against the alternative,

And, Hₐ: p > 0.35, the z test statistic is found to be 2.45.

Now, We get;

P(z < 2.45) = 0.9929

Hence, Significant is,

⇒ 1 - 0.9929 = 0.0071

Thus, Significant at both 0.05 and 0.01 because both are greater than 0.0071.

So, The correct statement is,

⇒ The finding is significant at both α = 0.05 and α = 0.01.

Step-by-step explanation:

4 + 8 divided by 2 * (6 - 3)

=> 12 divided by 2 * (3)

=> 12 divided by 6

=> 12/6 = 2.

The given expression 4 + 8 / 2 x (6 - 3) is equal to 16.

PEMDAS is an acronym that stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). It is a mathematical order of operations that helps to simplify expressions and solve mathematical problems in a consistent manner. The PEMDAS rules dictate the order in which operations should be performed in an expression to ensure that the correct answer is obtained.

The given expression is,

4 + 8 / 2 x (6 - 3)

Solve by using PEMDAS rule,

Step-by-step explanation:

Step 1

For Ritu,

Principal(P) = Rs 100

Time(T) = 5 year

Rate(R) =8%pa

Intrest (I) = ???

We know,

I = P*T*R /100

= 100*8*5/100

=Rs40

now

For Jitu,

Principal(P) =Rs 100

Rate(R)=9%pa

Time (T) = 4 year

Intrest(I) =?

We have

I = P*T*R/100

=100*4*9/100

=Rs36

Step 2

We have

Intrest of Ritu have more then that of Jitu so she makes more profit

now Profit diffrence =Rs40-Rs36

=Rs4

Therefore Ritu gets 4 more profit then Jitu

Given:

Line segment labelled y is the midsegment of the triangle.

To find:

The measures of x, y and z.

Solution:

Since line segment labelled y is the midsegment of the triangle. So, it divides the included sides in two equal parts.

Line segment labelled y is bisector of both included sides.

[tex]x=21[/tex] units

[tex]z=2\times 16[/tex]

[tex]z=32[/tex] units

According to the midsegments theorem, the length of the midsegment is half of third side or non included side of the triangle.

[tex]y=\dfrac{14}{2}[/tex]

[tex]y=7[/tex] units

Therefore, [tex]x=21\text{ units},y=7\text{ units},z=32\text{ units}[/tex].
