Seventy percent of kids who visit a doctor have a fever, and 30% of kids with a fever have sore throats. What’s the probability that a kid who goes to the doctor has a fever and a sore throat?

Answers

Answer 1

Answer:

0.21

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

Probability that a kid who goes to the doctor has a fever and a sore throat = probability a child would have fever x probability a child would have a sore throat

0.7 x 0.3 = 0.21

the diagram shows an isosceles triangle. all measurements are in cm.

3x-5 19-x
2x

work out the perimeter of the triangle

Answers

Answer: 38

Solution: An isosceles triangle has two equal sides: 3x - 5 and 19-x.; 3x - 5 = 19 - x; 4x = 24; x = 6

Let's check it out: 3(6) - 5 = 13; 19 - (6) = 13; 2(6) = 12

Two equal sides are 13 and base 12

Perimeter is 13 + 13 + 12 = 38 units

Answer is: 38

The perimeter of the given isosceles triangle is 38 cm.

What is the perimeter of an isosceles triangle?

The perimeter of an isosceles triangle refers to the addition of all the three sides of the triangle. Since the base angles of an isosceles triangle have two angles and two sides equal;

We can say that the perimeter of an isosceles triangle is:

P = 2a + b

where;

a = sides of the base anglesb = third side

3x - 5 =  19 - x

3x + x = 19 + 5

4x = 24

x = 24/4

x = 6

The perimeter of the isosceles triangle is:

= 3x - 5 + 19 - x + 2x

= 3(6) - 5 + 19 - 6 + 2(6)

= 18 + 8 + 12

= 38 cm

Answers

Answer:

The perimeter of the figure is approximately 42.85.

Step-by-step explanation:

Based on the given values, you already know that two of the sides of the shape are 12 units long. Since the half-circle above the rectangle is the same size as the gap in the rectangle - you know this because both of the half-circle's diameter are 6 units long - so you can add 24 units to the perimeter of a circle with a diameter of 6. The diameter of the circle is [tex]6\pi[/tex], or approximately 18.85, so the perimeter of the whole figure is approximately 42.85.

-38d - 57 > -19d + 76

Answers

Answer:

d < -7

Step-by-step explanation:

-38d - 57 > -19d + 76

Add 19d to both sides

-19d - 57 > 76

Add 57 to both sides

-19d > 133

Divide both sides by -19

(when multiplying or dividing by a negative the inequality is reversed)

d < -7

Answer:

d < -7

Step-by-step explanation:

-38d - 57 > -19d +76

Add 19d and 57 to both sides

-19d > 133

Divide both sides by -19 (dividing by negative flips the inequality sign)

d < -7

The height of the triangle is found by solving triangle AMV for the distance MV. That is found from the trig relation ...

  Tan = Opposite/Adjacent

  tan(68°) = MV/AM

The length of AM is half the diagonal of the square base, so is (10√2)/2 = 5√2. The length of MV is ...

  MV = AM·tan(68°) = 5√2·tan(68°) ≈ 17.50

So, the volume of the pyramid is ...

  V = (1/3)Bh

  V = (1/3)(100 cm²)(17.50 cm) ≈ 583.4 cm³ . . . . volume of the pyramid

Step-by-step explanation:

The segments are equal in length, SR = TR, so set up an equation:

[tex]\frac{y^2}{12}=y[/tex]

Multiply by 12.

[tex]y^2=12y\\y^2-12y=0[/tex]

Factor out the y on the left side.

[tex]y(y-12)=0[/tex]

There are two solutions:  y = 0 and y = 12.  The y = 0 solution makes no sence (segment SR can't have a length of 0).  The other solution, y = 12, works just fine.
