Answer:
x= 1/2 and x= -3
Step-by-step explanation:
Let's solve your equation step-by-step.
2x2+5x−3=0
Step 1: Factor left side of equation.
(2x−1)(x+3)=0
Step 2: Set factors equal to 0.
2x−1=0 or x+3=0
x=
1
2
or x=−3
Answer:
t = -1.862, df = 399, p > 0.05
Step-by-step explanation:
The null hypothesis is the statement which is test for its validity. The decision to accept or reject the null hypothesis is based on the test statistics value. In the given question the null hypothesis is H0 = 34. There is one sample t-test for the testing of null hypothesis. The null hypothesis will be same for each type of one sample t-test. The null hypothesis assumes that the difference between the true mean and comparison value is zero.

135 times because 675 divided by 5 is 135. you would divide the number of her heart beats by the number
Answer:
0.00673
Step-by-step explanation:
As each of the 10000 leaflets has equal chance on landing into 1 of the 2000 blocks, this means each leaflet has a probability of 1/2000 to land on the 1st block, 1/2000 to land on the 2nd lock, 1/2000 to land on the 3rd block, and so on.
The probability that a particular block will receive no leaflet is chance of each leaflets to land on the other 1999 blocks, which has a chance of 1999/2000. For all 10000 leaflets to happen like this independently, then the total probability is
