Answer:
Step-by-step explanation:
Given the decimal value 588.55
The ones digit value is 8
The tens digits value is 80
Taking the ratio
The ones digits/the tens digits = 8/80
The ones digits/the tens digits = 1/10
The ones digits = 1/10 * the tens digits '
Hence the value of the ones digit is 1/10 of the value of the tens digit.
Option C is correct
Answer:
the mango cost 1.75$ each and the peach 0.75$
Step-by-step explanation:
M= mango
P=peach
we know that Hudson spend 16$ buying 7 mangos and 5 peaches. So we can write the equation
(1) 16=7M+5P---> (2)P=(16-7M)/5
and we know that Austin spend 14.50 buying 4 mangos and 10 peaches.
we write the equation
(3)14.50=4M+10P
and we replace the P with the equation (2)
14.5=4M+10*(16-7M)/5
14.5=4M+2*(16-7M)
14.5-32=4M-14M
M=1,75$
and now we replace M in eq. (2)P=(16-7*1.75)/5=0.75$
Answer:
3/5
Step-by-step explanation:
Given
Number of women in the math class = 7
Number of men = 9
Total = 9 + 7 = 15
Probability of selecting a man at random to come to the board and show solution to a math problem
= number of men/total number of persons in the class
That’s
9/15
Divide both the numerator and denominator by 3
3/5
The probability of picking a man student is 3/5
6(2x-11)+15=21
12x-66+15=21
12x=21-15+66
12x=72
x=72/12
=6
This is the answer and way of solving
Hope this helps
All the best
Answer:
Option ii is right
Step-by-step explanation:
Given that according to the U.S. Department of Education, approximately 57% of students attending colleges in the U.S. are female.
(Two tailed test at 5% significance level)
Test statistic =1.42
Here since proportions we use Z test
p value = 0.156
(ii) P-value =0.156
