Yoshi is making blueberry muffins. He needs 1 1/4 cups of blueberrie to make 1 batch pf muffins. How many cups will he need to m

AURORKA [14]

Answer: $3\dfrac{1}{8}\ \text{cups}$

Step-by-step explanation:

Given

Yoshi need $1\frac{1}{4}$ cups of blueberries to make 1 batch of muffins

convert mixed fraction to fraction

$\Rightarrow 1\dfrac{1}{4}=\dfrac{5}{4}$

i.e. $\frac{5}{4}$ cups are required for 1 batch of muffins

for $2\frac{1}{2}$ batch or $\frac{5}{2}$ batch it is given by

$\Rightarrow \dfrac{5}{2}\times \dfrac{5}{4}\\\\\Rightarrow \dfrac{25}{8}=3\dfrac{1}{8}\ \text{cups}$

A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?

Bumek [7]

Answer:

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft

For Normal distribution with mean u 400

taurus [48]

Answer:

Step-by-step explanation:

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".

Solution to the problem

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

Where and

We are interested on this probability

And the best way to solve this problem is using the normal standard distribution and the z score given by:

If we apply this formula to our probability we got this:

And we can find this probability using the normal standard table or exce:
