Palace help me solve these two equations 14, 15

IrinaVladis [17]

14)

check the picture below... so.. is just a semi-circle and a rectangle, nothing fancy, get their area, sum them up.

15)

so... the voter turnout, is referring to, what's the percentage that voted, which year has the highest percentage... well, we simply check the percentage of the value provided from the total eligible voters, keeping in mind that, all eligible voters are the 100%

so.. for 1944

$\bf \begin{array}{ccllll}
amount&\%\\
------&----\\
86,607,000&100\\
47,976,670&x\\
\end{array}\implies \cfrac{86,607,000}{47,976,670}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 47,976,670}{86,607,000}\implies x\approx 55.39583405498$

for 1984

$\bf \begin{array}{ccllll}
amount&\%\\
-----&-----\\
167,727,000&100\\
92,659,000&x
\end{array}\implies \cfrac{167,727,000}{92,659,000}=\cfrac{100}{x}
\\\\\\
x=\cfrac{100\cdot 92,659,000}{167,727,000}\implies x\approx 55.2439380660239$

1. A certain manufacturing process to build phone batteries results in the production of defective batteries at a rate of 5% (0.

lesya [120]

Answer:

0.5 ; 0.475 ; 0.689 ; 0.4013

Step-by-step explanation:

Given that:

Rate of production of defective batteries p = 0.05

Number of batteries produced (n) = 10

The expected number of defective batteries = mean = n * p = 10 * 0.05 = 0.5 batteries

Variance of defective batteries :

Var(X) = n * p * q ; q = 1 - p

Hence,

Var(X) = 10 * 0.05 * 0.95 = 0.475

Standard deviation (X) = sqrt(variance) = sqrt(0.475) = 0.689

Probability that atleast 1 battery is defective :

Using the binomial probability function

P(x ≥ 1) = 1 - p(x = 0)

= 1 - q^n

= 1 - 0.95^10

= 1 - 0.59873693923837890625

= 0.40126306076162109375

= 0.4013
