Suppose 70% of kids who visit a doctor have a fever, and 45% 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?I am stuck on this question, sadly I just did a lot of these for my exams but I forget how to solve it. Someone help??

Answers

Answer 1

Answer: To find the probability that a kid has both a fever and a sore throat, multiply the two probabilities together: 70% * 45% = 31.5%

Answer 2

Answer: 70/100 = 0.7%
45/100 = 0.45%
0.7 x 0.45 = 0.31
0.31= 31%
31% is your answer sir

What is the value of x?

Answers

We can see on the number line that the bracket is 4 units long,
and the label above it says that it's (-3x + 1) long.

-3x + 1 = 4

Subtract 1 from each side: -3x = 3

Now divide each side by -3 : x = -1

$|2-(-2)|=-3x+1\n\n-3x+1=|2+2|\n\n-3x+1=|4|\n\n-3x+1=4\ \ \ \ |subtract\ 1\ from\ boh\ sides\n\n-3x=3\ \ \ \ \ \ |divide\ both\ sides\ by\ (-3)\n\n\boxed{x=-1}$

What is the area of the kitchen floor in this floor plan?A-24 sq meters
B-28 sq meters
C-35 sq meters
D-42 sq meters

Answers

Answer: The correct option is (C) 35 sq. meters.

Step-by-step explanation: We are given to find the area of the kitchen floor in the floor plan shown in the figure.

From the figure, we see that

the kitchen is in the form of a rectangle with length 7 meters and breadth 5 meters.

We know that

the area of a rectangle with length l units and breadth b units is given by

$A=l* b.$

For the rectangular kitchen, we have

length, l = 7 meters

and

breadth, b = 5 meters.

Therefore, the area of the kitchen floor in the floor plan is given by

$A=l* b=7* 5=35~\textup{sq. meters}.$

Thus, option (C) is CORRECT.

First you would figure out the dimensions, which are 7 ft by 5 ft. Then, multiply those together, which equals 35 sq ft. The answer to your question is C - 35 sq ft. Hope this helps!

When two musical notes are a “sixth” apart, the frequency of the lower note is 3/5 the frequency of the higher note. Using f as the frequency of the higher note, write an expression for the frequency of the lower note. HELP!1. f - 2/5

2. 3/5 f

3. 2/5 f

4. 3/5 + f

Answers

The correct expression for the frequency of the lower note when two musical notes are a sixth apart is: 3/5 f

Given that two musical notes are a “sixth” apart, the frequency of the lower note is 3/5 the frequency of the higher note.

We need to determine the expression for the frequency of the lower note.

When two musical notes are a "sixth" apart, it means that there are five whole steps or intervals between the two notes.

In music theory, each whole step corresponds to multiplying the frequency by a constant factor.

If we denote the frequency of the higher note as f, then the frequency of the lower note, which is 3/5 times the frequency of the higher note, can be calculated by multiplying f by 3/5.

Therefore, the correct expression for the frequency of the lower note is 3/5 f.
