There are markings given in the diagram.

(Angle) ∠A and ∠D are =

(Side) AC and DB are =

(Side) In a trapezium, the opposite sides are equivalent, meaning AB and DC are =

So you got side, angle, and another side.

You can form the SAS (Side-Angle-Side) similarity theorem.

You can also use the reasons above to make a Statement-Proof table

Solve the equation 3y-9x=-3

ipn [44]

This equation can have a number of solutions. Typically when solving a two-variable equation, you are looking for the slope intercept form of the line. In this case that is:

"The manager for State Bank and Trust has recently examined the credit card account balances for the customers of her bank and f

yuradex [85]

Answer:

$P(X = 4 ) = 0.1876$

$P(X \le 4) = 0.8358$

Step-by-step explanation:

From the question we are told that

The proportion that has outstanding balance is p = 0.20

The sample size is n = 15

Given that the properties of the binomial distribution apply, for a randomly selected number(X) of credit card

$X \ \ ~ Bin (n , p )$

Generally the probability of finding 4 customers in a sample of 15 who have "maxed out" their credit cards is mathematically represented as

$P(X = 4 ) = ^nC_4 * p^4 * (1 - p)^{n-4}$

=> $P(X = 4 ) = ^{15}C_4 * (0.20)^4 * (1 - 0.20)^{15-4}$

Here C stand for combination

=> $P(X = 4 ) = 0.1876$

Generally the probability that 4 or fewer customers in the sample will have balances at the limit of the credit card is mathematically represented as

$P(X \le 4) = [ ^{15}C_0 * (0.20)^0 * (1 - 0.20)^{15-0}]+[ ^{15}C_1 * (0.20)^1 * (1 - 0.20)^{15-1}]+\cdots+[ ^{15}C_4 * (0.20)^4 * (1 - 0.20)^{15-4}]$

=> $P(X \le 4) = 0.8358$

11^2^3x=983298f+0220.2^2(38) <br> whats x.

Mazyrski [523]

Answer:

x=1638831.492383738758729e+23f+0

Step-by-step explanation:

(1123)(x)=983298f+(220.22)(38)

Step 1: Divide both sides by 8.954302432552374e+23.

8.954302432552374e+23x

8.954302432552374e+23

983298f+1842545.52

8.954302432552374e+23
