Answer:

2 1/10

Steps:

You need both fractions to have the same denominator, you get 6/10 and 5/10

Subtract your fraction:

6/10 - 5/10 = 1/10

Then your whole numbers:

3 - 1 = 2

Then put your answers together:

2 1/10

Tom [10]

Answer:

log₅(3125) = 5

Step-by-step explanation:

Given:

log₅(3125)

Now,

using the property of log function that

logₐ(b) = $\frac{\log(b)}{\log(a)}$

thus,

Therefore, applying the above property, we get

⇒ $\frac{\log(3125)}{\log(5)}$ (here log = log base 10)

now,

3125 = 5⁵

thus,

⇒ $\frac{\log(5^5)}{\log(5)}$

Now,

we know from the properties of log function that

log(aᵇ) = b × log(a)

therefore applying the above property we get

⇒ $\frac{5\log(5)}{\log(5)}$

⇒ 5

Hence,

log₅(3125) = 5

Barbara sells iced tea for $1. 49 per bottle and water for $1. 25 per bottle. She wrote an equation to find the number of bottle

Sedbober [7]

The correct option is The Barbara equation did not consider the number of bottles of water.

Given,

The selling price of iced tea is $1.49 per bottle.

The selling price of water is $1.25 per bottle.

Equation written by the Barbara,

$1.25x+1.49=100$

Here in this question Barbara multiply the selling price of bottle with the number of bottle using the coefficient x, But she did not use any coefficient for the bottle of water. The correct equation is,

$1.25x+1.49y=100$

where<em> y </em>is the number of water bottle sold to earn the profit of $100.

Hence the correct option is the Barbara equation did not consider the number of bottles of water.

Height of Dutch Men. Males in the Netherlands are the tallest, on average, in the world with an average height of 183 centimeter

trapecia [35]

Answer:

a) $P(X$

$P(z$

b) $P(X>195) =P(Z>\frac{195-183}{10.5})=P(Z>1.143)$

$P(z>1.143)=1-P(Z$

c) $P(173$

$P(-0.953$

d) $P(\bar X >190)=P(Z>\frac{190-183}{\frac{10.5}{\sqrt{1000}}}=21.08)$

And using a calculator, excel ir the normal standard table we have that:

$P(Z>21.08)=1-P(Z$

So for this case we expect anyone with a heigth higher than 190 cm in a random sample of 1000.

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Part a

Let X the random variable that represent the heights of a population, and for this case we know the distribution for X is given by:

$X \sim N(183,10.5)$
