You cant simplify 7/10.
You would  be able to simplify a fraction if the numerator and denominator both have a number they both go into evenly.
For example: 10/40 or 7/21
For 10/40 you would divide your numerator and denominator by 10 because 10 goes into both 10 and 40
For 7/21 you would divide your numerator and denominator by 7 because 7 goes evenly into both 7 and 21.

Ivahew [28]

Answer: (0.066,0.116)

Step-by-step explanation:

The confidence interval for proportion is given by :-

p_1-p_2\pm z_{\alpha/2}\sqrt{\dfrac{p_1(1-p_1)}{n_1}+\dfrac{p_2(1-p_2)}{n_2}}

Given : The proportion of men have red/green color blindness = p_1=\dfrac{89}{950}\approx0.094

The proportion of women have red/green color blindness = p_2=\dfrac{6}{2050}\approx0.003

Significance level : \alpha=1-0.99=0.01

Critical value : z_{\alpha/2}=z_{0.005}=\pm2.576

Now, the 99% confidence interval for the difference between the color blindness rates of men and women will be:-

(0.094-0.003)\pm (2.576)\sqrt{\dfrac{0.094(1-0.094)}{950}+\dfrac{0.003(1-0.003)}{2050}}\approx0.091\pm 0.025\\\\=(0.09-0.025,0.09+0.025)=(0.066,\ 0.116)

Hence, the 99% confidence interval for the difference between the color blindness rates of men and women= (0.066,0.116)

son4ous [18]

total income= 2R-C-2P

R= omoun tof rent paid by each tenant = $700

C= cable bill = $100

P = Phone bill = $50

Replace the values:

Total income = 2(700)-100-2(50)

total income= 1,400-100-100 = 1,400-200= $1,200

Total income =$1,200
