Find the mode, median, and mean of each data set ( ASAP pls can someone help me )

Answer:

Step-by-step explanation:

-the angles need to add to 90° because they have to e complementary

- the cofunctions come in pairs (sin and cos, tan and cot, sec and csc)

for sin 7°

we know that function sin is paired with cos , and that the angles needs to add to 90° so we have 7° + 83° =90°

sin 7° = cos 83°, cos 83° is a cofunction of sin 7°

Step-by-step explanation:

If its 28 km for hour. A quarter of 28 is 7 so then 28+7=35 km.

Answer: 35 Km

Step-by-step explanation:

28 Km in 60 minutos. How many Km. In 75 minutes (One and one quarter hour =75min)

28/x = 60/75 (cross multiplication)

Answer:

10.6

Step-by-step explanation:

Pythagorean theorem: a² + b² = c²

Where a and b = the legs and c = hypotenuse

We are given two legs and need to find the hypotenuse

Given:

Short leg (a) = 7

Long leg (b) = 8

Hypotenuse = c

Now to find the value of c we simply plug in the values of the variables into the Pythagorean theorem and solve for c

Pythagorean theorem: a² + b² = c²

a = 7, b = 8, c = c

Plug in values

7² + 8² = c²

Now solve for c

Simplify exponents

49 + 64 = c²

Add

113 = c²

Taking the square root of both sides

c = 10.6 ( rounded to the nearest tenth )

Answer:

c = 10.6

Step-by-step explanation:

[tex]h {}^{2} = p {}^{2} + b {}^{2} \\ c {}^{2} = (8) {}^{2} + (7) {}^{2} \\ c = \sqrt{64 + 49} \\ c = \sqrt{113} \\c = 10.6[/tex]

Answer:

[tex] \frac{11}{b - 1} = \frac{6}{b + 1} \\ 11(b + 1) = (b - 1).6 \\ 11b + 11 = 6b - 6 \\ 11b + 11 - 11 = 6b - 6 - 11 \\ 11b - 6b = 6b - 17 - 6b \\ 5b = - 17 \\ \frac{5b}{5} = \frac{ - 17}{5} \\ b = \frac{ - 17}{5} \\ b = - 3.4[/tex]

[tex]\boxed{\underline{\bf \: Answer}}[/tex]

[tex] \sf \frac{11}{b + 1} = \frac{6}{b + 1} \\ [/tex]

Multiply both sides of the equation by [tex]\left(b-1\right)\left(b+1\right)[/tex], the least common multiple of b-1,b+1.

[tex]\sf\left(b+1\right)\times 11=\left(b-1\right)\times 6 [/tex]

Use the distributive property to multiply b+1 by 11.

[tex]\sf11b+11=\left(b-1\right)\times 6 [/tex]

Subtract 6b from both sides.

[tex]\sf11b+11-6b=-6 [/tex]

Combine 11b and -6b to get 5b.

[tex]\sf5b+11=-6 [/tex]

Subtract 11 from both sides.

[tex]\sf5b=-6-11 [/tex]

Subtract 11 from -6 to get -17.

[tex]\sf5b=-17 [/tex]

Divide both sides by 5.

[tex]\sf \: b=\bf\frac{-17}{5} [/tex]

=> The correct answer is [tex]\bf \: b=\frac{-17}{5} [/tex] or [tex]\bf \: b= -3.4 [/tex] (✓).

Every student will get 8 candies.

Division is a process of splitting a specific amount into equal parts.

Given that, A teacher has 104 pieces of candy, which she equally divides to her 13 students.

Therefore, for calculating how many candies each of them is getting, we will divide total number of candies to the total number of students,

Therefore, 104/13 = 8

Hence, we get that every student will get 8 candies.

Step-by-step explanation:

8(b ÷ 2) - (c + 4)

(Putting values of b = 1/2 and c = 1/4)

[tex] = 8( \frac{1}{2} \div 2) - ( \frac{1}{4} + 4)[/tex]

[tex] = 8( \frac{1}{2} \times \frac{1}{2} ) - ( \frac{1 + 16}{4} )[/tex]

[tex] = 8 \times \frac{1}{4} - \frac{17}{4} [/tex]

[tex] = 2 - \frac{17}{4} [/tex]

Answer:   x = -1/2

Step-by-step explanation:

1/2 x - 3/10  =  5/2 x + 7/10

-1/2 x on both sides

-3/10 = 4/2 x +7/10

subtract 7/10 from both sides

-1 = 4/2x

simplify

2x = -1

divide 2 on both sides

x = -1/2
