I have 7 hundreds 3 ones 12 tens and 8 tenths. What number am i?

What's 2 + 2 x 10?<br><br> !0 x 1,00 = ?<br><br> 1,000 x 1,00,00=?

iragen [17]

Answer: 2 + 2 x 10 = 22

10 x 100 (?) = 1,000

1,000 x 10,000 (?) = 10,000,000

Step-by-step explanation:

For A, (2 + 2 x 10), you need to multiply first, 2 x 10 = 20. Then, you must add 2, which equals 22.

For B, which is (10 x 100, I think) you will multiply the top number by the bottom number, let’s say 100 is on the top. You will line thin up, 100 x 10. You will need to multiply 0 times 100, which is 000. You will then need to move over a slot, and then times 100 by 1. After doing that then you add your numbers, which gives you 1,000.

For C you do the same steps you used for B.

A researcher wants to study the relationship between salary and gender. She randomly selects 297 individuals and determines thei

padilas [110]

Answer:

The researcher cannot conclude that salary and gender are dependent.

Step-by-step explanation:

A dependent variable is a variable, for example "Salary" that depends on an independent variable, e.g. "Gender." Salary is the dependent variable while gender is the independent variable. This means that the value of salary changes in relation to the gender and not vice versa. Two variables become dependent if they change based on another independent variable that is operating on them. In this research, the researcher is not trying to measure gender but the relationship between salary and gender. To achieve her purpose, she shows that salary depends on gender and not that gender depends on salary.

Two step equation; 0.7t - 3.2 = 1.7

Kaylis [27]

0.7t = 1.7+3.2

0.7t = 4.9

0.7t/0.7 = 4.9/0.7

t=7

There are 50 students in a calculus class. The amount of time needed for the instructor to grade a randomly chosen midterm exam

natta225 [31]

Answer:

14.46% probability that the instructor can finish grading in 4 and a half hours

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal probability distribution

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.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .
