In the number 913,874 which number digit is in the ten thousands place?

2 answers:

6 0

The digit 3, because if you start from 4 and say tenth, 7 and say hundredth, 8 and say thousandth, then 3 must be ten thousandth.
Hope this Helps ;)

Slav-nsk [51]

She walked three more dogs per day, so that means 3 dogs x 7 days. 21 dogs total that week. Subtract that from this week's total. 35-21=14. That would be 14 dogs that week, which is 7 days, so 14/7=2. She walked two dogs per day last week.

Answer:

The percentage of students sudy 34 hours or more is 0.62%

Step-by-step explanation:

The Normal Distribution

The bell curve or normal distribution is frequently used to model the probability of natural random events. The normal distribution $N(\mu,\sigma)$ is characterized by two parameters:

$\mu$ is the mean value

$\sigma$ is the standard deviation

The study times in hours for the final exam is modeled as a normal distribution N(24,4). We are required to find the percentage of students study 34 hours or more, or P(X>34).

The values for the cumulative probability are given by tables or digital means like Excel where we can get the left-tail or P(X<Xo). To compute the right-tail or P(X>Xo) we use this relation

$P(X>Xo) =1-P(X$

The Excel formula to find the left-tail cumulative probability is called

NORM.DIST(x,mean,standard_dev,cumulative)

To solve the question, we used:

NORM.DIST(34,24,4,TRUE)=0.9938

Thus:

$P(X>34) =1-P(X$

The percentage of students study 34 hours or more is 0.62%

For circle H, JN = x, NK = 2, LN = 3, and NM = 6. Solve for x.

Advocard [28]

Answer:

The value of x is 9 ⇒ C

Step-by-step explanation:

In a circle, if two chords intersected at a point inside it there are four segments created, two in each cord, the products of the lengths of the line segments on each chord are equal.

Let us use this rule to solve the question

In circle H

∵ Jk and LM are chords intersected at point N inside the circle

∴ The created segments are JN, Nk, and LN, NM

→ By using the rule above

∴ JN × NK = LN × NM

∵ JN = x and NK = 2

∵ LN = 3 and NM = 6

→ Substitute these values in the equation above

∴ x × 2 = 3 × 6

∴ 2x = 18

→ Divide both sides by 2 to find x

∴ $\frac{2x}{2}=\frac{18}{2}$

∴ x = 9

∴ The value of x is 9
