Mrs Adams baked some muffins. Carl eat 2/5 of the muffins and John eat 25. How many muffins were baked?

Mathematics

Dennis_Churaev [7]3 years ago

Answer:


Well, how many were left over? Mrs. Adams has a muffin factory and made 1 million muffins. Carl ate 2/5 or 40% or 400,000 muffins, and John ate 25. 599,975 muffins were shipped for sale. That meets the stated requirements.


Hence, we have to guess there were supposed to be no muffins left over.


In that case, Mrs. Adams baked 125/3 muffins, Carl ate 2/5 of them = 50/3, leaving 75/3 = 25 for John.



Step-by-step explanation:

x muffins baked, 2/5 eaten by Carl, 3/5 left to be eaten by John, who ate 25 before running out.


3/5 x = 25

x = 25 × 5/3 = 125/3 = 41 + 2/3


Or, Start with x muffins. Carl ate 2/5 x, leaving 3/5 x. John ate 25 with zero left over. So 3/5 x = 25.


(x - 2/5 x) - 25 = 0

3/5 x = 25

x = (5/3) × 25 = 125/3.

4. The diagonal of a rectangle is 13cm. The breadth is 5cm. Find it's length. *​
Citrus2011 [14]

Answer:

The length of the rectangle is

12

c

m

and the area of the rectangle is

60

c

m

2

.

Explanation:

By definition, the angles of a rectangle are right. Therefore, drawing a diagonal creates two congruent right triangles. The diagonal of the rectangle is the hypotenuse of the right triangle. The sides of the rectangle are the legs of the right triangle. We can use the Pythagorean Theorem to find the unknown side of the right triangle, which is also the unknown length of the rectangle.

Recall that the Pythagorean Theorem states that the sun of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

Since the length of the side is a measured distance, the negative root is not a reasonable result. So the length of the rectangle is

The area of a rectangle is given by multiplying the width by the length.

A student wanted to estimate the number of chocolate chips in a commercial brand of cookie. He sampled 100 cookies and found an
m_a_m_a [10]

Answer: A. (8.4,12.6)

Step-by-step explanation:

Confidence interval(\mu) is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

, where n is the sample size

\sigma = Population standard deviation.

\overline{x}= Sample mean

z_{\alpha/2} = Two tailed z-value for significance level of \alpha.

Given : Confidence level = 99% = 0.99

Significance level = \alpha=1-0.99=0.01

By standard normal z-value table ,

Two tailed z-value for Significance level of 0.01 :

z_{\alpha/2}=z_{0.005}=2.576

Also,

n=100

\sigma= 8

\overline{x}=10.5

Then, the required 99% confidence interval for the average number (\mu) of chips per cookie :-

10.5\pm (2.576)\dfrac{8}{\sqrt{100}}\\\\ =10.5\pm 2.0608\\\\=(10.5-2.0608,\ 10.5+2.0608)=(8.4392,\ 12.5608)\approx(8.4,\ 12.6)

Hence, the 99% confidence interval for the average number of chips per cookie = (8.4,12.6)
