Answer:
Option B is correct
36 pizzas were topped with vegetables
Step-by-step explanation:
Let x be the number.
As per the statement:
At a pizzeria, the ratio of pizzas topped with meat to pizzas topped with vegetables was 4:3 on Saturday.
The ratio of pizza topped with meat to pizzas topped with vegetables = 4 : 3
then;
the number of pizza topped with meat = 4x
and
the number pizza topped with vegetables = 3x
It is also given that the pizzeria made a total of 84 pizzas that day.
Substitute the given values we get;
Combine like terms;
Divide both sides by 7 we get;
12 = x
The pizza were topped with vegetables = 3x = 3(12) = 36
therefore, 36 pizzas were topped with vegetables
Answer:
10 + 0.8 + 0.006 = 10.806
Step-by-step explanation:
Pick any two decimal numbers. The third one will be the difference between 10.806 and the sum of the two numbers you picked.
For example, choose 938.2 and 3.0055. Their sum is 941.2055. Then the third number that will make the sum be 10.806 is ...
10.806 -941.2055 = -930.3995
So, your three numbers could be ...
{938.2, 3.0055, -930.3995}
Answer:
$0.85
Step-by-step explanation:
2 juice pouches- $2.50
3c+2.50=5.05 (c is for bags of chips)
3c=5.05-2.50
3c=2.55
c= $0.85
So one bag of chip is $0.85
Answer:
The critical t values are -1.746 and 1.746.
Step-by-step explanation:
Given information:
The weight of a USB flash drive is 30 grams and is normally distributed.
Population mean = 30
Sample size = 17
Sample mean= 31.9
Standard deviation = 1.8
Significance level, α=0.10
Null hypothesis: 
Alternative hypothesis: 
It is a two tailed test.
The t-critical values for a two-tailed test, for a significance level of α=0.1 are -1.746 and 1.746.
Therefore the critical t values are -1.746 and 1.746.
Percent means per one-hundred
300(10/100)=30
So 30 of the 300 workers were satisfied with their benefits.
