Answer:

$1182.65

Step-by-step explanation:

(8.5/100)×$1090

(85/1000)×1090

$1853/20

=$92.65

thus, $1090+$92.65

=$1182.65

Answer: a= -9

Step-by-step explanation:

a+ (−4) = −13

a - 4 = -13 (the 4 becomes -4 as when it comes to + or - it is always -)

    a = -13 +4  (when you switch the side -4 becomes +4)

    a= -9

The likelihood of 8 occurrences in a period of 10 minutes is around 0.091 or 9.1%.

According to the Question

A Poisson distribution issue exists here. The Poisson distribution is a discrete probability distribution that quantifies the likelihood of a certain number of events occurring at a certain average rate, regardless of the interval between occurrences, in a given amount of time or space.

The following formula determines the likelihood that x will occur in a Poisson distribution with parameter λ :

P(x; λ) is equal to x / (λx * e(-λ))!

where

λ = the average number of occurrences within the specified time period.

λ in this situation is 4.2. (the mean number of occurrences in 10 minutes).

In order to determine the likelihood of 8 occurring in 10 minutes:

P(8; 4.2) = (4.2^8 * e^(-4.2)) / 8!

⇒ P(8; 4.2) = 0.091 or 9.1%.

When a number is randomly selected from the set of consecutive integers, it has a 3/4 chance of being divisible by 1995.

A branch of mathematics called probability theory determines the likelihood that an event will occur or that a statement is true. A chance is a number between zero and 1, where 1 denotes certainty and about 0 denotes how probable an event is to occur. The possibility or chance that a specific event will occur is expressed numerically as a probability. Probabilities can also be expressed in percentages ranging from 0% to 100% or as numbers between 0 and 1. the proportion of occurrences among all equally likely alternatives that lead to a certain occurrence relative to all possible outcomes.

given

99-20+1 = 80 potential outcomes.

Now, a number that may be divided by 12 must include the digits 2*2*3.

The realisation that c(c21)(21) = c(c1)c(c+1) is the same as c3c3 is perhaps the trickiest.

The latter statement indicates that you indeed have a group of three consecutive integers that are divisible by 12. Every three consecutive integers must be divisible by three, according to a rule.

The main question is how many of the numbers you choose are divisible by 22=4 22=4.

In this scenario, c can either be 21, 23, 25, 95, 97, 99, so 99212 9921/2 + 1 = 40 OR 20, 24, 26, 92, 96, so 96204 9620/4 + 1 = 20.

Thus, 40+2080 = 60/80 and 40+20/80 = 40/80

60/80 = 3/4

When a number is randomly selected from the set of consecutive integers, it has a 3/4 chance of being divisible by 1995.

Answer: A confidence interval is a range of values that is likely to contain the true population value with a certain level of confidence. To determine a 95% confidence interval for the percentage of people who prefer Candidate A, we can use the following formula:

(Sample proportion) +/- (Margin of error)

The margin of error can be calculated using the formula:

Margin of error = (Critical value) * (Standard deviation)

The critical value is a factor used to compute the margin of error. The critical value for a 95% confidence interval is approximately 1.96. The standard deviation is calculated as:

Standard deviation = √((Sample proportion) * (1 - Sample proportion) / (Sample size))

Plugging in the given values:

Sample proportion = 80% = 0.8

The required amount each type of solution to make mixture are  120 ml of 25% acid and 80 ml of 50% acid.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The letter "%" stands for it.

A liquid mixture known as an acidic solution is created when water and hydrogen ions react. The Brnsted-Lowry theory states that whereas bases "receive" hydrogen protons, acids "give" hydrogen protons. Different solutions have different levels of acidity.

Let there be (200 - x) ml of 50% acid and x ml of 25% acid.

200*0.35 = 0.25x+0.5(200-x)

0.25x +100 -0.5x = 70 

30 = 0.25x 

x=120

Let W be the width of rectangle.

then, length of the rectangle is W + 6 .
