A cake recipe suggests a cooking temperature of 325 degree Fahrenheit if the batter is less than one inch thick and 350F if the

bija089 [108]

The first step is finding the height of the cake. The formula for the volume of a box: Volume= length x width x height. So given the volume and length and width: 100= 9 x 11 x h. 100=99h and solve for h. h= 1.01 inches so the batter is more than one inch thick. That means that the matter needs to be baked at 350 degrees Fahrenheit. The formula to convert from Fahrenheit to Celsius: T(C)= (T(F)-32) x (5/9). So (350-32) x (5/9) = 176.667. Rounded to the nearest whole number is 177 degrees celsius.

Debi walks laps around the mall for exercise during the winter months. The table represents the number of steps recorded on her

MariettaO [177]

Answer:

The correct option will be: b. One lap around the mall is equal to about 2,425 steps.

Step-by-step explanation:

Here, we will just find the slope of the line representing Debi’s data. For that, we will take any two data from the table in form of point like $(x,y)$

Lets take two points as $(0, 1875)$ and $(2, 6725)$

Formula for finding the slope is: $m= \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$ , where $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ are two given points.

Here, $x_{1}= 0 , y_{1}= 1875 , x_{2}=2 , y_{2}=6725$

So, plugging these values into the above formula, we will get......

$m= \frac{6725-1875}{2-0}=\frac{4850}{2}=2425$

That means, one lap around the mall is equal to about 2,425 steps.

The weight of a small Starbucks coffee is a normally distributed random variable with a mean of 330 grams and a standard deviati

just olya [345]

Answer:

Weights of at least 340.1 are in the highest 20%.

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 330, \sigma = 12$
