Answer:
Step-by-step explanation:
Given
See attachment for dataset
Solving (a): Percentage to accept
The percentage to accept are flea collars that range between 14mg to 16mg (inclusive)
From the attachment, we have:
--- Number of 14mg to 16mg
So, the percentage to accept is:
Solving (b): Collars to reject
In (a), we have:
The number to reject is then calculated by subtracting the collars to accept from the total (this is called complement rule)
So, we have:
<em>11 will be rejected</em>
Answer:
ΔDBE≅ΔQAP (by RHS criteria)
Step-by-step explanation:
Given that, , , ⊥
and ⊥
⇒∠PAQ=90° and ∠EBD=90°(definition of perpendicular lines)
Its given that PB=AE,
subtracting AB on both sides,
we get: PB-AE=AB-AE
⇒PA=EB (equals subtracted from equals, the remainders are equals)
Therefore, ΔDBE≅ΔQAP (by RHS criteria)
conditions for congruence:
- ∠DBE=∠QAP=90°(right angle)
- PQ=ED(hypotenuse)
- PA=EB(side)
So, ∡D=∡Q(as congruent parts of congruent triangles are equal)
Uh we don’t know how to help with this answer we need more context sorry :(
Answer:
The rectangle is a parallelogram.
Step-by-step explanation:
Parallelograms are shapes with two pairs of parallel sides.
The rectangle is the only shape that meets those requirements.
Answer:
The mean is 4.
Step-by-step explanation:
Mean simply means average. To do so, just add up all the numbers and divide by the amount of numbers present.
2 + 5 + 5 + 6 + 7 + 1 + 2 = 28/7 = 4
