Two friends shop for fresh fruit. Elena buys a watermelon for $7.45 and 3 pounds ofcherries. Taniy buys a pineapple for $3.35 an

Scrat [10]

Let's use the variable E to represent the total value spent by Elena and T to represent the total value spent by Taniy.

If Elena spent $7.45 plus the cost of 3 pounds of cherries, the expression for the amount she spent is:

$E=7.45+3p$

Taniy spent $3.35 plus the cost of 2 pounds of cherries, so the expression for the amount the spent is:

$T=3.35+2p$

To find how much more Elena spent, let's subtract both expressions:

$\begin{gathered} E-T\\ \\ =7.45+3p-(3.35+2p)\\ \\ =7.45+3p-3.35-2p\\ \\ =4.1+p \end{gathered}$

Therefore the answer is 4.1 + p.

A rectangular prism has a length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm. A similar prism has a length of 14.7 cm,

solong [7]

They are each multiplied by a factor of 3.5
You can calculate this by taking the length of the similar prism and divide it with the first prism 14.7/4.2 = 3.5
Do this with the width and height to be sure
20.3/5.8 = 3.5
33.6/9.6 = 3.5

A multiple choice test has four possible answers for each question. Let X be the number of correct responses in a test of 100 qu

dimulka [17.4K]

Answer:

a. 4.33.

Step-by-step explanation:

If there is only one correct answer out of four alternatives, the expected proportion of correct answers is p =0.25

Sample size (n) = 100 questions

The standard deviation of a proportion 'p' is given by:

$s=\sqrt{\frac{p*(1-p)}{n} }$

Applying the given data:

$s=\sqrt{\frac{0.25*(1-0.25)}{100}}\\s=0.0433$

If X is the number of correct responses in 100 guesses, the standard deviation of X is:

$\sigma = n*s=100*0.0433\\\sigma = 4.33$

The standard deviation of X is 4.33 questions.
