Answer:1800 words
Step-by-step explanation:
Multiply how many words per minute she types by how many minutes she types. In this case 60x30=?. The easy way to do this is drop the 2 zeros and do 6x3=18. In the original equation we dropped the 2 zeros. Now we add them back on the back of the 18 and get 1800.
Answer: A
<u>Step-by-step explanation:</u>
CD bisects ∠BCD and ∠ACD, so
∠BCD = ∠ACD
5x - 20 = 3x - 2
<u>-3x +20</u> <u>-3x + 20</u>
2x = 18
<u>÷2 </u> <u> ÷2 </u>
x = 9
∠BCD = 5x - 20 = 5(9) - 20 = 45 - 20 = 25
∠BCD + ∠CDB + ∠DBC = 180°
25 + 90 + ∠DBC = 180°
115 + ∠DBC = 180°
<u> -115 </u> <u>-115 </u>
∠DBC = 65°
Answer:
All of these could do this.
Step-by-step explanation:
Normal distribution is a form of probability distribution that is symmetric about the mean, to depict data near the mean are more frequent in occurrence than data far from the mean. Normality of data can be measured by either power or the Shapiro-Wilk test.
Some ways of testing the normal distribution of data are by:
i. Histogram, which is a data visualization that shows the distribution of plotted sample data. The frequency of occurrence per value in the data set determines its distribution.
ii. Interpretation of the shape.
iii. Probability plot of the data, e.g Box Plot, QQ Plot etc. If the dots fall exactly on the black line, then a given sample of data are normal. If not, otherwise.
iv. Calculating interquartile range (IQR), which is a measure of variability. Sample of data are normally distributed when the interquartile range (IQR) is 1.34896.
Therefore, all the given methods could be used to determine if the data is normally distributed.
