Answer:
john's age= x + 5
his sister's age= x
x + 5 + x = 150
2x + 5 = 150
2x = 150 - 5
2x = 145
x = 145 ÷ 2
x = 72.5
so, 72.5 + 5 = 77.5
john's present age is = 77.5
his sister's present age is = 72.5
Answer: 95% confidence interval would be (0.555,0.745).
Step-by-step explanation:
Since we have given that
n = 97
x = 63
So, we get that
At 95% confidence interval , z = 1.96
so, Margin of error would be
So, interval would be
Hence, 95% confidence interval would be (0.555,0.745).
<span>Label the place value 12 354.897
=> the given numbers are mixed number. We have the whole number which is 12
354 and the decimals which id 897.
Now, Let us label each digit’s place values:
1 – ten thousands = equals to 10 000
2 – thousands = equals to 2 000
3 – hundreds = equals to 300
5 – tens = equals to 50
4 – ones = equals to 4
.8 – tenths = equals to 8/10
.09 – hundreds = equals to 9/100
.007 – thousands = equals to 7/1 000</span>
