Mhm.... Word problems.. So! Angle Side Angle :) proving that 2 triangles are equal.
You need to prove that DC is equal to BA. Now....
DB == AC.
which you can subtract BC from both sides!
DB-BC = AC-CB. leaving you with DC= AB

Now by Side Angle Side, The angles are =, 2 sides are equal, means the 2 triangles are equal :) If the triangles are equal, the 2 remaining sides must be equal

The length of needles produced by a machine has standard deviation of 0.04 inches. Assuming that the distribution is normal, how

Lana71 [14]

Answer:

The sample size is $n = 87$

Step-by-step explanation:

From the question we are told that

The standard deviation is $\sigma = 0.04 \ inches$

The precision is $d = \pm 0.005 \ inches$

The confidence level is $C =$ 98%

Generally the sample size is mathematically represented as

$n = \frac{ Z_{\frac{\alpha }{2} } ^2* \alpha^2 }{d^2}$

Where $\alpha$ is the level of significance which is mathematically evaluated as

$\alpha = 100 - 98$

$\alpha = 2$ %

$\alpha = 0.02$

and $Z_{\frac{\alpha }{2} }$ is the critical value of $\alpha$ which is obtained from the normal distribution table as 2.326

substituting values

$n = \frac{2.326 ^2* 0.02^2 }{0.005^2}$

$n = 87$

rodikova [14]

With 6.75 cups of yogurt , we can make 4 bowls of fruit dip.

Step-by-step explanation:

We have ,Themba has 6.75 cups of yoguri and needs to make 5 bowls of fruit dip. Each bowl uses 1.5 cups of yogurt .

With 1.5 cups of yogurt:

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (6.75 - 1.5 = 5.25) cups of yogurt. Number of bowls of fruit dip = 1.

With another 1.5 cups of yogurt:

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (5.25 - 1.5 = 3.75) cups of yogurt. Number of bowls of fruit dip = 2.

With another 1.5 cups of yogurt:

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (3.75 - 1.5 = 2.25) cups of yogurt. Number of bowls of fruit dip = 3.

With another 1.5 cups of yogurt:

With help of 1.5 cups of yogurt one bowl of fruit dip is made. Now we are left with (2.25 - 1.5 = 0.75) cups of yogurt. Number of bowls of fruit dip = 4.

Now, Another bowl of fruit dip couldn't be made because we have only 0.75 cups of yogurt ! So, with 6.75 cups of yogurt , we can make 4 bowls of fruit dip.
