6 0

Answer:

45

Step-by-step explanation:

Since this is only three terms

Find the three terms and add

j=1   3(1)^2+1 = 3+1 =4

j=2   3(2)^2+1 = 3(4)+1 =13

j=3   3(9)^2+1 = 27+1 =28

The sum is 4+13+28 =45

Suppose KLMN ~ PQRS. Find the value of x.
arlik [135]

Complete question is attached.

Answer:

B) 8

Step-by-step explanation:

In this question, KLMN ~ PQRS. This means they are similar shapes.

From the image, we could denote that:

KL ~ PQ

LM ~ QR

Given that:

KL = 12

PQ = 30

QR = 20

LM = x

To find x, let's use tge expression:

\frac{KL}{PQ} = \frac{LM}{QR}

=  \frac{12}{30} = \frac{x}{20}

Cross multiplying, we have:

12 * 20 = 30x

240 = 30x

To find x, let's divide both sides by 30.

\frac{240}{30} = \frac{30x}{30}

8 = x

x = 8

The correct option is option B.

nika2105 [10]

Answer:

attached below

Step-by-step explanation:

Attached below are the Venn diagrams

A :  48 < X < 52   cm

B : 9 < Y <  11 cm

a) A

b) A ∩ B

c) A' ∪ B

d) A ∪ B

e)  for events to be mutually exclusive it means that both events can not occur simultaneously i.e. A ∩ B = 0

the process would not be successful hence the process would not produce parts with X = 50 cm and Y = 10 cm
