I need an operation, sweetheart. Are you looking for a sum, difference, what?
THE TRIANGLE EQUALS 6....................
Answer:
$7.08
Step-by-step explanation:
59 cents = 1 sq ft
? = 12 sq ft
To get from the 1 to the 12 we multiply by 12, so we must do the same to the 59 cents.
0.59 * 12 = 7.08
Therefore, the cost of 12 sq ft is $7.08.
Please mark brainliest if possible and have a nice day.
Answer:
a. 0.9049
b. 0.2297
c. 0.8473
Step-by-step explanation:
Given U = 46.7, SD = 1.75
and Z = (U - X)/sd
(a). We want to find P(X<=49)
P(X<=49) = P(Z<= 49-46.7/1.75)
= P(Z<= 1.31)
= 0.90490
~= 0.9049
(b) P(X>=48) = P(Z>=48-46.7/1.75)
=P(Z>=0.7429) = 1 - P(Z<=0.7429)
= 1 - 0.77035
= 0.22965
=0.2297
(c) The required probability is given by P(U±2.5).
P(46.7±2.5) = (44.2<= X <=49.2)
= P( 44.2<= Z <= 49.2)
= P(44.2 - 46.7/1.75 <= Z <= 49.2- 46.7/1.75)
= P( - 1.4286 <= Z <= 1.4285)
= P(1.4285) - P(-1.4285)
= P(1.43 ) - P(-1.43)
= 0.92364 - 0.07636
= 0.8473
Answer:
area : 63.9
b : 14.2
write equation of area of a triangle
Step-by-step explanation:
area:. 1/2 × B x H
solve for H : H= _2x_area_
B
Substitude values : _H = _2×63.9___
14.2.
Evaluate : H = 9
