Answer:
-15.
Step-by-step explanation:
The temperature dropped 3°c every hour.
So, the change in temperature every hour = -3°C.
Total number of hours for which the temperature were changed =5.
Thus, the total change in temperature = change for an hour x total number of hours,
= -3° x 5
= -15°.
Answer:
3x-4(4) =65
3x-16 =65
3x=65+16
3x=81
x = 27
Step-by-step explanation:
HOPE THAT THIS IS HELPFUL. HAVE A GREAT DAY.
Answer:
<em>0.08192</em>
Step-by-step explanation:
Given 50, 20, 8, ...
The sequence is geometric in nature
The nth term of the geometric sequence is exoressed as;
Tn = ar^{n-1}
a is the first term = 50
r is the common ratio = 20/50 = 8/20 = 2/5
n is the number of term = 8 (since we need the 8th term)
Substitute
T8 = 50(2/5)^{8-1}
T8 = 50(2/5)^7
T8 = 50(128/78,125)
T8 = 0.08192
<em>Hence the 8th term is 0.08192</em>
47 degrees
Work:
90+43+x=180
133+x=180
-133 -133

Hi,thank you for posting your question here at Brainly.
Probability is a numerical value that represents a fraction of a whole. Since there are 4 samples indicated in row X, then there must be 4 probabilities corresponding to each. The sum of all those probabilities must equal to 1. With this information, we could already find the missing probability.
Summation of P = 1 = 0.40 + 0.20 + 0.20 + x
x = 1 - 0.4 - 0.2 - 0.2
x = 0.2 <-- missing probability
