Answer:
| 573 |
Step-by-step explanation:
The product of a 1×2 matrix and a 2×1 matrix will be a 1×1 matrix. The value of the only term will be the dot-product of the row of the first matrix and the column of the second matrix.
P = | 17·27 +19·6 | = | 573 |
Answer:
See below.
Step-by-step explanation:
Part A:
triangle QPR and triangle PSR are similar
Part B:
Triangle QPR is a right triangle with right angle QPR.
Triangle SPR is a right triangle with right angle PSR.
Angle QPR of triangle QPR corresponds to and is congruent to angle PSR of triangle PSR.
Angle R of triangle QSR corresponds to and is congruent to angle R of triangle PSR.
The similar triangles by AA Similarity are
triangle QPR and triangle PSR
Part C:
QR/PR = PR/SR
16/PR = PR/4
PR² = 16 * 4
PR² = 64
PR = 8
Answer:
s = -4 ± √31
Step-by-step explanation:
Given 4
+ 32s = 60
divide by 4 throughout
s = -4 ± √31
Answer:
The frequency table is attached below.
Step-by-step explanation:
Given the total number of candies in the box = 18
Frequency table is used to list the occurence of a thing or product and it helps to calculate and sort down easily.
<u>Contains caramel</u> <u>Do not contain caramel</u> Total
<u>Contains chocolate</u> 10 2 12
<u>Do not contain </u> 3 3 6
<u>chocolate</u>
Total number of candies as per the frequency tablr = 12 + 6 = 18 which tallies with the given data.
