Answer:

17 cm

Step-by-step explanation:

P=2L+2W

L=22, P=78 we want to find W

78=2(22)+2W

78=44+2W

34=2W

W=17 cm

Consider the following cumulative probability distribution.

Marat540 [252]

The solution $P(x \leq 4),p{x= 3), p(2 \leq * \leq 4)$ is mathematically given as

$P(2 \leq X \leq 4)=0.84$
P(X=3)= 0.17

$P(2 < =X\leq 4)=0.53$

<h3>What is the solution $P(x \leq 4),p{x= 3), p(2 \leq * \leq 4)$ ?</h3>

Generally, the equation for the Probability of P(X=3) is mathematically given as

$P(X=3) = P(X \leq 3)-P(X\leq 2)$

Therefore

$P(X=3)= 0.65-0.48$

P(X=3)= 0.17

$P(2\leq X\leq 4) = P(X\leq 4)-P(X\leq 1)\\\\\\P(2\leq X\leq 4) = 0.84-0.31'$

$P(2 < =X\leq 4)=0.53$

$P(2\leq X\leq 4)=0.84$

Given: △ACE, BD∥AE<br><br> Prove: BA/CB=DE/CD<br><br> Drag

gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

Angle 4 = angle 1 and angle 3 =angle 2 Corresponding angles for two parallel lines BD and AE

Triangle AED ||| BDE Angle angle congruent

... By compendo and dividendo

Thus proved

Since two lines are parallel we have corresponding angles equal and also

sides will be proportional in similar triangles

Using that and adjusting compendo and dividendo we get the desired result

HELP ME! Look at the stem-and-leaf plot. What is the mode of the numbers?

S_A_V [24]

Given:

The stem-and-leaf plot or a date set.

To find:

The mode of data set.

Solution:

From the given stem-and-leaf plot, we get the numbers of the data set.

64, 67, 70, 70, 71, 75, 76, 78, 78, 80, 82, 82, 88, 91, 93, 94, 97, 98, 100, 100, 100

Mode of a date set is the most frequent value.

In the given data set the most frequent value is 100 with frequency 3.

Therefore, the mode of data set is 100. Hence, option A is correct.

Complete the proof for me please, I need help

Naya [18.7K]

Answer:

See explanation for answers

Step-by-step explanation:

Reason 1) Given from the problem statement(because it says that B is the midpoint of AC)

Reason 2) Because B is the midpoint of AC

Reason 3) Given frome the problem statement(because it says that AB/cong CD)

Reason 4) Because two lines congruent to each other have the same length

Reason 5(You didn't explain well)) BC=AB=CD, so BC=CD(Specific reason: Transitivity of equality)

And we're done!
