If 40% reps 98
100% will rep (98/50)*100 = 245
Answer:
Option (D). 536.2 yd³
Step-by-step explanation:
Radius of the circular base of the cone = 8 yd
Height of the given cone = 8 yd
Formula for the volume of the cone =
Here r = radius of the circular base of the cone
h = height of the cone
By substituting the values of r and h in the formula,
V =
=
= 526.165
≈ 526.2 yd³
Therefore, volume of the given cone is 526.2 yd³.
Option (D) will be the answer.
Answer:
1. 30°
2.
3. 20cm
4. 5cm
Step-by-step explanation:
for the first one:
we have the triangle RVT and we know that
so = 180
so
for the second one
we know by specials right triangles that the sides are
divide by x and get
for the third one
again by 30-60-90 triangle we know that
for the fourth one
here we can use excersie 3 and the ratio of XY:YC = 1:1
that means they are equal so
XY=YC
XY = 5
The interval of systolic blood pressure will be between 155 to 95
<h3>
What is the standard deviation?</h3>
Standard deviation is defined as the amount of variation or the deviation of the numbers from each other.
From the question, we are told that
Mean x=125
Standard deviation = 10
The Percentage for men =99.75%
Generally, the empirical rule 68%,95% and 99.7% of data value lay b/w 1,2,3 standard deviation of mean
Standard deviation n= 10
Mean x= 125
Generally, the interval of systolic blood pressure for middle 99.7 of male G is mathematically given as
G = Mean ± (3x )
G= 125 ± (3 x 10)
G= 125 ± (30)
G = 155 and 95
Hence the interval of systolic blood pressure will be between 155 to 95
