Which are partial products for 68 × 43?

blagie [28]

Partial products are the products obtained during the intermediate stages in order to complete a multiplication process.

Consider 68 $\times$ 43, we have to determine the partial products in this.

Now, $68 \times 43$

Expanding this, we get

$(60+8) \times (40+3)$

= $(60\times 40) +(60 \times 3) + (8 \times 40) + (8 \times 3)$

= 2400 + 180 + 320 + 24

= 2924

Hence, $8 \times 40=320$ and $8 \times 3 = 24$ are the required partial products in the product of 68 and 43.

So, Option 3 and 4 are the correct answers.

Carlos conducts a study comparing the performance of individuals on the first quiz in each of two classes taken in the first ter

podryga [215]

Answer:

-0.46

Step-by-step explanation:

We have small sample sizes n1 = 9 and n2 = 9. $\bar{x}_{1} = 85.11$ , $\bar{x}_{2} = 86.56$ ; $s_{1} = 7.47$ , $s_{2} = 5.75$ .

$s_{p}^{2} = \frac{(n_{1}-1)s_{1}^{2}+(n_{2}-1)s_{2}^{2}}{n_{1}+n_{2}-2} = \frac{(9-1)(7.47)^{2}+(9-1)(5.75)^{2}}{9+9-2} = 44.43$

Because Carlos conducts a study comparing the performance of individuals on the first quiz in each of two classes taken in the first term of their freshman year, the hypothesis null is $H_{0}: \mu_{1}-\mu_{2} = 0$ , then, the observed t-value is

$t=\frac{(\bar{x}_{1}-\bar{x}_{2})-0}{s{p}\sqrt{1/n1+1/n2}} = \frac{-1.45}{6.67(0.47)} = -0.46$
