Answer:
Step-by-step explanation:
PQRS is a parallelogram with QR = 6 cm, QT = 3 cm and ∠PSR = 115°.
a). By the property of a parallelogram,
"Diagonals of a parallelogram bisect each other"
QT = TS
QS = 2(QT)
= 2(3)
= 6 cm
b). "Adjacent angles of a parallelogram are supplementary"
m∠PSR + m∠SRQ = 180°
115° + m∠SRQ = 180°
m∠SRQ = 65°
c). Since, SQ = SR = 6 cm
m∠QSR = m∠SRQ [Opposite angles of the equal sides of an isosceles triangle]
m∠QSR = 65°
By applying triangle sum theorem in ΔQSR,
m∠SQR + m∠QRS + m∠QSR = 180°
m∠SQR + 65° + 65° = 180°
m∠SQR = 50°
Answer:
45820
Step-by-step explanation:
the "10" means adding 1 zero to "4582" in place value
Hundred Thousand= 4
Thousand= 5
Hundred= 8
Tens= 2
Units= 0
Answer: 34 but I’m not 100% sure but that might be right
Answer:
A - 220
B - 205
Step-by-step explanation:
29% of 759 is 220.11, round down so it stays 220.
27% of 759 is 204.93 round up so it becomes 205.
bonus:
44% of 759 is 333.96 round up and it becomes 334.
to check your work, add 220, 205, and 334 and its 759. thats how you can be sure its correct.
hope this helps :)
Let p be 0.831 denote the percentage of defective welds and q be 0.169 denote the percentage of non-defective welds.
Using the binomial distribution, we want all three to be defective.
