A triangle has to equal 180 degrees.

Brrunno [24]3 years ago

Answer:

Step-by-step explanation:

All three angles of any type of triangle should add up to 180 degrees

So if x (the degree of one angle)plus x+65(the degree of the other angle) plus 25(the degree for the third angle) equals 180, the equation should look like this

x+(x+65)+25=180

2x+65+25=180

2x+90=180

2x=90

x=45

So x equals 45, but we are not done yet

The question says to define x+65, so

x+65

45+65

110 is the answer

Answer:

$2400

$12,400

Step-by-step explanation:

Simple interest equation:

PV(1+it)

we have

10000(1+.06*4)

10000(1.24)

12400

Subtract the PV to get the interest earned

12400-10000= 2400

We just found that the total would be 12,400 and so part B is already solved

On a baseball team, the ages of each of the players are as follows: 21; 21; 22; 23; 24; 24; 25; 25; 28; 29; 29; 31; 32; 33; 33;

Answer:

Mean = 30.68

Standard deviation = 6.095

Two standard deviations above the mean = 42.87

Step-by-step explanation:

Given the following data :

21; 21; 22; 23; 24; 24; 25; 25; 28; 29; 29; 31; 32; 33; 33; 34; 35; 36; 36; 36; 36; 38; 38; 38; 40

Mean = Σ(x) / n

n = 25

Σ (X) = 767

Mean (m) = 767 / 25

Mean (m) = 30.68

Standard deviation : sqrt[Σ(x - m) / n]

Using a calculator :

Standard deviation = 6.095 ( 2 decimal places)

2 standard deviations above the mean :

Mean + 2(standard deviation)

Mean + 2(6.095)

30.68 + 12.19

= 42.87

Seventy percent of children who go to the doctor have fevers. Of those with fevers, 30% also have a rash. Of those without fever

Allisa [31]

Answer:

The probability that a child with a rash does not have a fever is 22%

Step-by-step explanation:

1. Probability of having fever:

$P(fever)=0.70$

2. Probability of not having fever:

$P(not fever)=1-P(fever)\\P(not fever)=1-0.70\\P(not fever)=0.30$

3. Probability of fave fevers and a rash:

$P(fever and rash)=(0.70)(0.30)=0.21$

4. Probability of having a rash but not a fever:

$P(rash and not fever)=(0.30)(0.20)=0.60$

5. Probability of having a rash:

$P(rash)=P(rash and fever)+P(rash and no fever)\\P(rash)=0.21+0.06=0.27$

6. Probability a child with a rash does not have a fever

$P=\frac{P(rash and not fever)}{P(rash)} =\frac{0.06}{0.27} =0.22$

22% of the child at the doctor's office with a rash does not have a fever.
