WILL GIVE BRAINLIEST! <br>What is the answer for question (iv)? <br>please help! ​
Leviafan [203]

Step-by-step explanation:

\triangle ABC \sim \triangle ADE... (given) \\\\\therefore \frac {AC}{AE} = \frac {BC}{DE}.. (csst) \\\\\therefore \frac {5}{5+2x} = \frac {x+3}{4x+1}\\ \\ \therefore \: 5(4x + 1) = (5 + 2x)(x + 3) \\ \therefore \:20x + 5 = 5x + 15 + 2 {x}^{2}  + 6x \\ \therefore \:20x + 5 =2 {x}^{2} +  11x + 15 \\ \therefore \:2 {x}^{2} +  11x + 15 -2 0x  - 5 = 0\\  \therefore \:2 {x}^{2}  - 9x + 10 = 0\\ \therefore \:2 {x}^{2}  - 5x   -  4x+ 10 = 0\\ \therefore \:x(2x - 5) - 2(2x - 5) = 0 \\ \therefore \:(2x - 5)(x - 2) = 0 \\ 2x - 5 = 0  \:  \: or \:  \: x - 2 = 0 \\ x =  \frac{5}{2} \:  \:  or \:  \: x = 2 \\ x = 2.5 \:  \: or \: x = 2 \\ x = 2.5 \: is \: largest \\  \\  \frac{A(\triangle ABC)}{ A(\triangle ADE)} =  \frac{AC ^{2} } {AE^{2} } \\  \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} =  \frac{5 ^{2} } {(5 + 2x)^{2} } \\  =  \frac{25}{(5 + 2 \times 2.5)^{2} }  \\  =  \frac{25}{ {10}^{2} }  \\  =  \frac{25}{100}  \\  \\  \frac{A(\triangle ABC)}{ A(\triangle ADE)} =  \frac{1}{4}  \\

A certain drug treatment cures 90% of cases of hookworm in children.18 Suppose that 20 children suffer- ing from hookworm are to
Anni [7]

Answer:

Step-by-step explanation:

Here X the no of children suffering from hookworm treated and recovered is binomial because

a) Each child is independent of the other

b) There are only two outcomes

c) The probability for any child to recover is constant as 90% = 0.9

X is Bin (20,0.9)

a) Prob that all 20 will be cured

=P(X=20)=0.9^{20} \\=0.1216

b) Prob all but 1 will be cured=P(x=1) = 20C1 (0.9) (.1)^{19} \\=1.8(10^8)

c) Prob exactly 18 will be cured

=P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852

d) Prob exactly 90% will be cured.

=P(X=18)\\=20C18 (0.9)^{18} (0.1)^2\\= 0.2852

Solomon can buy four sodas for $6 how much would 6 sodas cost
Bad White [126]

Answer:

6 soda's will cost $9.

Step-by-step explanation:

4 soda's costs $6.

Find the amount 2 soda's will cost. Divide 2 from both sides.

(4)/2 = 2

(6)/2 = 3

2 soda's will cost $3.

Now, solve for the cost for 6 soda's by multiply 3 to both sides.

2(3) = 6

3(3) = 9

6 soda's will cost $9.
