Answer:
$280
Step-by-step explanation:
35%=$98 (to find 1%: 98/35) 1%=$2.8 100%=$280
Answer:
.
Step-by-step explanation:
Given:
In Right Angle Triangle GIH
∠ I = 90°
GI = 7 ....Side opposite to angle H
GH = 10 .... Hypotenuse
To Find:
m∠H = ?
Solution:
In Right Angle Triangle ABC ,Sine Identity,
Substituting the values we get;
Now taking we get;
rounding to nearest tenth we get.
.
Hence .
Answer:
3
Step-by-step explanation:
3x+2y=12
5x-7=y
3x+2(5x-7)=12
3x+10x-14=12
13x=12+14
13x=26
x=2
3(2)+2y=12
6+2y=12
2y=12-6
y=6/2
y=3
No, u cant
a^2 + b^2 = c^2.....pythagorean theorem used on only right triangles...where a and b are the legs and c is the hypotenuse
a^2 + b^2 = 23^2
a^2 + b^2 = 529...so u would have to find 2 square numbers that add up to 529. There aren't any.
Using the normal distribution, it is found that 25.14% of the batteries will last more than 420 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, we have that the mean and the standard deviation are given, respectively, by:
.
The proportion of the batteries will last more than 420 hours is <u>one subtracted by the p-value of Z when X = 420</u>, hence:
Z = 0.67
Z = 0.67 has a p-value of 0.7486.
1 - 0.7486 = 0.2514.
0.2514 = 25.14% of the batteries will last more than 420 hours.
