Answer:

x= 20

Step-by-step explanation:

Solve for x:

(7 x)/10 = 14

Multiply both sides of (7 x)/10 = 14 by 10/7:

(10×7 x)/(7×10) = 10/7×14

10/7×7/10 = (10×7)/(7×10):

(10×7)/(7×10) x = 10/7×14

10/7×14 = (10×14)/7:

(10×7 x)/(7×10) = (10×14)/7

(10×7 x)/(7×10) = (7×10)/(7×10)×x = x:

x = (10×14)/7

14/7 = (7×2)/7 = 2:

x = 10×2

10×2 = 20:

Answer: x = 20

Answer:1866

Step-by-step explanation:

Given

n=200

x=118

Population proportion P= $\frac{118}{200}$ =0.59

$\alpha$ =0.005

Realiability =99%

$Z_{\frac{\alpha }{2}}=2.576$

Margin of erroe is given by $\sqrt{\frac{p\left ( 1-p \right )}{N}}$

0.03= $\sqrt{\frac{0.59\left ( 1-0.59 \right )}{N}}$

85.667= $\sqrt{\frac{N}{0.6519}}[tex]N=1865.88[tex]\approx 1866 Students$

Answer:

2.5cm^2

Step-by-step explanation:

so diameter is basically radius*2...to find radius(since area of circle is pi*r^2 we need to divide diameter by 2)

so 1.8/2=0.9

now,

pi*0.9^2

pi*0.81

2.5 cm^2

What is the IQR (Inter Quartile Range) for the data set?

vladimir2022 [97]

Arrange in ascending order:-

6 7 11 13 14 15 15 19 21

median = 14
lower quartile = mean of 7 and 11 = 9
upper quatile = mean of 15 and 19 = 17

Interquartile range = 17 - 9 = 8

answer is 8
