The answer would be 15%

You find it by taking 10,000 and subtracting 8,500 to get $1,500.

Now just take $1500 and divide by the actual amount (10,000) and get 0.15 (15%)

A shop sells chocolate, vanilla and strawberry ice creams. 45% of the ice creams sold are vanilla, and 1/4 are strawberry. What
Mamont248 [21]

Answer:

30%

Step-by-step explanation:

Since we want percentage, we need to convert 1/4th to percentage first.

We will divide, get decimal, and then multiply by 100 to get percentage.

1/4 = 0.25

0.25 * 100 = 25%

Now, we can say:

45% + 25% + chocolate = 100%

70% + chocolate = 100%

chocolate = 100 - 70 = 30

Chocolate = 30%

Open Brains data. SETUP: Some people believe that first born subjects have different intelligent (different IQ test). Given the
melamori03 [73]

Answer:

the test I will perform is d. ​​Two-sided t-test

Step-by-step explanation:

When we are to compare between different data, critical regions occur on both sides of the  mean of a normal distribution,they are as a result of two-tailed or two-sided tests.

In such tests, consideration has to be given to values  on both sides of the mean.

for this question, it is expected to compare weather it is true that first born have different intelligent or not, weather to accept a null hypothesis or reject.

For example, if it is  required to show that the percentage of metal, p, in a

particular alloy is x%, then a two-tailed test is used,  since the null hypothesis is incorrect if the percentage  of metal is either less than x or more than x.
