Answer:

a. $\frac{3}{4}$ teaspoons

Step-by-step explanation:

You didn't show in the image that each batch makes 12 cupcakes, but I remember that from the other problems of yours that I helped with.

We know that each batch is 12 cupcakes and we want 36 cupcakes. This means that we will have to triple the recipe.

This means that we can triple the value of baking powder which is $\frac{1}{4}$ tsp

$\frac{1}{4} *3=\frac{3}{4}$

A tire company finds that the lifespan for one brand of its tires is normally distributed with a mean of 47,500 miles and a stan

Illusion [34]

Answer:

42580 miles

Step-by-step explanation:

Mean = $\mu = 47500$

$\sigma = 3000$

The manufacturer does not want to replace more than 5% of the tires

$P(X\leq x)=5\%$

$P(\frac{x-\mu}{\sigma}\leq \frac{x-47500}{3000})=0.05$

By using normal table values :

$\frac{x-47500}{3000}=-1.64$

$x=(-1.64 \times 3000)+47500$

$x=42580$

Hence the approximate number of miles for the warranty is 42580 miles

arsen [322]

Answer:

576

Step-by-step explanation:

First off, we can use the area of a kite formula, (D1*D2)/2 to get the area of one side of the kite, which is simplified to 18 * 32 : which gets us 288. But because we are looking for the area of the front and back side, we multiply 288 by 2- getting the final answer of <u>576</u>.
