Answer:
375 sweaters sold, 125 sweaters did not sell
Step-by-step explanation:
A percent is the piece of the whole or total. 25% decrease means the total of 500 sweaters must be decreased by 25% or 1/4. We multiply 500 by 0.25 and get 125. This means that 125 less sweaters sold then expected. To find the number of sales which did occur we subtract 125 from 500.
500(0.25)=125
500-125=375 sweaters sold
Theoretical probability is what we expect to happen, where experimental probability is what actually happens when we try it out. The probability is still calculated the same way, using the number of possible ways an outcome can occur divided by the total number of outcomes.
Answer:
her grandson would be 7 and her granddaughter would be 5.
Step-by-step explanation:
their ages together is 12. we divide that by the two grandchildren, and adjust it to where they are to years apart.
12÷2=6
6+6 + adjusted = 5 and 7.
to fact check 5+7=12, and 7 is two numbers above 5.
Answer:
89.8 feet
Step-by-step explanation:
In ΔBCD, the measure of ∠D=90°, the measure of ∠B=75°, and DB = 93 feet. Find the length of BC to the nearest tenth of a foot.
We would solve the above question using Sine rule
The formula is given as:
DB/sin D = BC/sin B
93/sin 90 = BC/sin 75
We cross multiply
sin 90 × BC = 93 × sin 75
BC = 93 × sin 75/sin 90
BC = 89.83 feet
Approximately BC = 89.8 feet
