Answer:
A
Step-by-step explanation:
Here, we want to select which of the options is greater than Ryan’s decimal but less than Sarah’s
Ryan shades 70 out of 100 so his decimal will be 70/100 = 0.7
Sarah shades 80 out of 100, so his decimal will be 80/100 = 0.8
So we want a decimal greater than Ryan’s but less than Sarah’s
Let’s take a look at the options
The first option would be 70/100 = 0.7 + 4/100 = 0.7 + 0.04 = 0.74
We can see that this is greater than 0.7 but less than 0.8
So, this is our answer
Answer:
Step-by-step explanation:
For this case we have a linear model given by:
Where X= represent the height.
Y= represent the beats per minute
And the slope is given by 
and the intercept 
We have the mean for x and y given also 
And in order to find the best predicted value we just need to replace the value of X= 65, and we got this:
If we want a confidence interval for the response variable when the predictor variable is x, is given by this formula:
And if we replace we got this:
But for this case since we don't have the deviation we can just express it like this.
Answer:
10
Step-by-step explanation:
Square root of 100 is 10
Yes it is.
2(5/8)=(2*5)/8=10/8
10(1/8)=(10*1)/8=10/8

In △ABD and △ACD, we have
DB=DC ∣ Given
∠ADB=∠ADC ∣ since AD⊥BC
AD=AD ∣ Common
∴ by SAS criterion of congruence, we have.
△ABD≅△ACD
⇒AB=AC ∣ Since corresponding parts of congruent triangles are equal
Hence, △ ABC is isosceles.
