r-ruslan [8.4K]

Answer:

a) Kylie has 8 marbles

b) 7 Cylinders

c) 17 carrots

d) 8 marbles belong to Shauntay

Step-by-step explanation:

5. Identify the type and subtype of each of the fol-

lowing problems.

a. Shawn has 15 marbles, which is 7 more marbles than Kyle has. How many marbles does Kyle have?

Shawn = 15 marbles

S = K + 7

15 = K + 7

K = 15 - 7

K = 8 marbles

Kylie has 8 marbles

b. Tiffany has 12 blocks, 5 of which are cubes and the rest cylinders. How many blocks are cylinders?

T = 12 blocks

Cubes = 5

Cylinders = the rest

12 blocks = Cubes + Cylinders

Cylinders = 12 - Cubes

Cylinders = 12 - 5

Cylinder = 7

c. Peter had some carrots. After he ate 3 of them, he had 14 carrots left. How many carrots did Peter have before?

Number of carrots Peter has before

= Number of carrots he ate + Number of carrots he has now

= 14 + 3

= 17 carrots

d. In a bag of 17 marbles, 9 marbles belong to Kelly and the rest belong to Shauntay. How many marbles belong to Shauntay?

Total number of Marbles = 17

Kelly = 9 marbles

Shauntay = ?

Total = Kelly + Shauntay

Shauntay = Total - Kelly's marbles

= ( 17 - 9) marbles

= 8 marbles

8 marbles belong to Shauntay

A 98% confidence interval for the mean of a population is to be constructed and must be accurate to within 0.3 unit. A prelimina
BaLLatris [955]

Answer:

n = (\frac{2.326*1.7}{0.3})^2= 173.73

And the value for n rounded up would be n = 174

Step-by-step explanation:

We have the following info given:

s= 1.7 previous estimation for the deviation

ME=0.03 the margin of error desired

Conf =0.98 represent the confidence

The Margin of error is given by:

ME = z_{\alpha/2} \frac{\sigma}{\sqrt{n}}

If we solve for the value of n we got:

n= (\frac{z*\sigma}{ME})^2

For this problem we know that the confidence is 98% so then the significance level would be \alpha=0.02 and the critical value would be:

z_{\alpha/2}= 2.326

And replacing we got:

n = (\frac{2.326*1.7}{0.3})^2= 173.73

And the value for n rounded up would be n = 174
