You have to use your area equations.like basex height
Answer:
X=1 because 2+5=7 then X=1 cause 1*2=2
Step-by-step explanation:
Answer:
<h3>Each of the given pairs is not a solution to the given equation.</h3>
Step-by-step explanation:
Put the x and y values in the equation 4y = -7x + 5 and check the equality of the left and right side of the equation.
A. x = -5 and y = 0
L = 4(0) = 0
R = -7(-5) + 5 = 35 + 5 = 40
L ≠ R
B. x = -3 and y = 4
L = 4(4) = 16
R = -7(-3) + 5 = 21 + 5 = 26
L ≠ R
C. x = 1 and y = 3
L = 4(3) = 12
R = -7(1) + 5 = -7 + 5 = -2
L ≠ R
D. x = 2 and y = -2
L = 4(-2) = -8
R = -7(2) + 5 = -14 + 5 = -9
Answer:
0.9544
Step-by-step explanation:
We are given that mean=18 and standard deviation=1 and we have to find P(16<X<20).
P(16<X<20)=P(z1<Z<z2)
z1=(x1-mean)/standard deviation
z1=(16-18)/1=-2
z2=(x2-mean)/standard deviation
z2=(20-18)/1=2
P(16<X<20)=P(z1<Z<z2)=P(-2<Z<2)
P(16<X<20)=P(-2<Z<0)+P(0<Z<2)
P(16<X<20)=0.4772+0.4772=0.9544
The probability that the height of a tree is between 16 and 20 feet is 95.44%
