Lia is cooking.She needs 2 3/4 cups of flour and 4 3/4 cups of cornmeal.Lia wants to bake sure she has a bowl big enough to hold

Sholpan [36]

Answer:

Lia needs $7\frac{2}{4}\ cups$ of flour and corn meal.

Step-by-step explanation:

Given:

Amount of flour needed = $2\frac{3}{4} \ cups$

$2\frac{3}{4} \ cups$ can be Rewritten as $\frac{11}{4}\ cups$

Amount of flour needed = $\frac{11}{4}\ cups$

Amount of Corn meal needed = $4\frac{3}{4}\ cups$

$4\frac{3}{4}\ cups$ can be Rewritten as $\frac{19}{4}\ cups$

Amount of Corn meal needed = $\frac{19}{4}\ cups$

We need to find the total amount of of flour and cornmeal she needs.

Solution:

Now we can say that;

the total amount of of flour and cornmeal she needs is equal to sum of Amount of flour needed and Amount of Corn meal needed.

framing in equation form we get;

the total amount of of flour and cornmeal she needs = $\frac{11}{4}+\frac{19}{4}=\frac{11+19}{4}=\frac{30}{4}\ cups\ \ OR\ \ 7\frac{2}{4}\ cups$

Since Answers are not given:

Kindly chose the answer which contains below data.

Hence Lia needs $7\frac{2}{4}\ cups$ of flour and corn meal.

What’s the correct answer for this?

ololo11 [35]

As you can see in the picture, this is 6-8-10 right triangle.

One of angles is 90° so you can find others

$\tan( \alpha ) = \frac{opp}{adj}$

8/6 = 4/3

6/8= 3/4

tan-1(4/3) = 36.9 °

tan-1(3/4) = 53.1 °

tan<R= 53.1 °

Hope this helps ^-^

The scores on a Psychology exam were normally distributed with a mean of 67 and a standard deviation of 8. Create a normal distr

Trava [24]

Answer:

(a) The percentage of the scores were less than 59% is 16%.

(b) The percentage of the scores were over 83% is 2%.

Step-by-step explanation:

Let the random variable X represent the scores on a Psychology exam.

The random variable X follows a Normal distribution with mean, μ = 67 and standard deviation, σ = 8.

Assume that the maximum score is 100.

(a)

Compute the probability of the scores that were less than 59% as follows:

$P(X$

$=P(Z$

*Use a z-table.

Thus, the percentage of the scores were less than 59% is 16%.

(b)

Compute the probability of the scores that were over 83% as follows:

$P(X>83)=P(\frac{X-\mu}{\sigma}>\frac{83-67}{8})$

$=P(Z>2)\\\\=1-P(Z$

*Use a z-table.

Thus, the percentage of the scores were over 83% is 2%.

(c)

It is provided n = 160 students took the exam.

Compute the probability of the scores that were over 75% as follows:

$P(X>75)=P(\frac{X-\mu}{\sigma}>\frac{75-67}{8})$

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

The percentage of students who received a score over 75% is 16%.

Compute the number of students who received a score over 75% as follows:

$\text{Number of Students}=0.16\times 160=25.6\approx 26$

Thus, the number of students who received a score over 75% is 26.

VARVARA [1.3K]

Answer:

53:2 Im sure.

Ratio is a comparison of two quantities. Online Simplifying ratios calculator is a ratio simplifier that simplify ratios in to its simplest form. For that ones should know the greatest common factor of both numerator and denominator. And then divide these two by the common factor. By using ratio in simplest form calculator one can simplify ratio from the high value to lower value in an easy way.
